September 4, 2014 Why is distillate cloudy?

A common distillation question is “why is my distillate cloudy?” As all commercial distillers know, properly made spirits and spirits should be crystal clear. Luckily, there are many ways to avoid haze or “haze”.

But before we go any further, a reminder: Distilling alcohol is illegal without a federal alcohol or spirits license and appropriate state permits. Our stills are designed for legal use only and the information in this article is for educational purposes only. Please read our full legal summary for more information on the legalities of distillation.

Solution #1 – Prevent “puke”.

Over the years we have found that about 99% of the time, distillate cloudiness is caused by a ‘puke’ into the collection vessel. Liquid in the boiler foams up into the column and then drips down through the condenser and drip arm. This is analogous to a pot of water slightly boiling over on a stove. If a distiller finds himself in the middle of a run and notices that the liquid in the receiver is cloudy, that means he probably just threw up! The good news is that this problem is very easy to fix. This can be remedied by lowering the still temperature.

Manage the temperature carefully

Just the right amount of heat must be applied to an alembic to function properly. If too much heat is applied, liquid will boil up into the column and vomit into the receiver, causing the distillate to become cloudy. If too little heat is applied, the distillation process will take much longer than it should.

To determine how much heat to add, a distiller will typically monitor still output to get a feel for what level of output corresponds to a cloudy distillate. They log the temperature input details and always stay below that level. Note that the total volume of liquid added to a still has an impact. A crowded still is more likely to puke.

Solution #2 – Eliminate fusel oils

Another potential source of cloudiness is oil. Fusel oils, which are produced at the end of the distillation process, can cause cloudiness in the distillate. Oils from plant material (when distilling essential oils) can also lead to turbidity. Interestingly, at low concentrations, oil can initially appear crystal clear, but as the liquid cools, it develops a cloudy haze. This is referred to as “chill haze”.

With essential oils, some cloudiness is often unavoidable. For distilled spirits and alcohol, to avoid “contamination”, the master distiller will turn off the still and end the process earlier to prevent fusel oils from entering the collection vessel.

Solution #3 – Use good water to lower the proof

Occasionally alcohol will be clear until “checked”. Proofing is a process distillers use to reduce the ABV of a solution to meet product and regulatory requirements. If clear spirits are “fermented” to 80 proof (40% ABV) and then go cloudy, it is most likely a high fusel oil content issue. However, certain types of tap water can also contribute to this problem. It doesn’t happen often, but if the tap water has a high mineral content, cloudiness may be more likely to occur.

Use filtered water

Most commercial distillers already know that using reverse osmosis water to proof spirits is preferred, but perhaps some don’t. Reverse osmosis water is highly filtered and nearly nutrient free. It is also very “neutral” in taste. This is why distillers use it for proofing, as it doesn’t alter the flavor profile of their product and because it also eliminates the chance of cloudiness forming. Additionally, most commercial distillers use RO water that’s the same temperature as the distillate they’re poofing, which also helps eliminate the possibility of chill haze. when mixing and the water must always be poured into the distillate.

There is a chance that the leftover yeast will burn when heated in a still (distillation), eventually spoiling the taste and smell of your moonshine. Clarification of the wash before distillation minimizes the risk of affecting the organoleptic properties of the distillate. The most commonly used clarifying substances are bentonite (recommended), gelatin, or hibiscus tea, but these are not always on hand. You can clarify the sugar wash with a more accessible substance – citric acid.

Theory. Acidic conditions prevent the yeast from working and cause it to precipitate in the form of sediment at the bottom of the fermentor. It’s easier and safer to create acidic conditions at home by adding citric acid to the wash. But it’s crucial to bring the pH of the liquid to neutral before proceeding with the distillation by slaking excess acid with baking soda or chalk. Otherwise, after distillation, the moonshine will be sour with a vinegar aftertaste.

Clarification with citric acid can only be used for sugar washing because of its aggressive effect on the fragrance. If you want to keep the smell of moonshine, do not use this method of clarification on grain and especially fruit washes.

Clarification Technology

Ingredients for 10 liters of laundry:

Citric Acid – 0.9 oz / 25 grams (1 flat tablespoon)

Baking soda or crushed chalk – 1 tablespoon

The acid can be replaced with freshly squeezed lemon juice. A medium-sized fruit contains up to 5-6 grams of acid.

Step by step guide

Decant the fermented wash by pouring it into another vessel, without touching the layer of sediment at the bottom. Mechanically degas the mash by stirring with a stick or with a drill fitted with a nozzle (in a plastic container only) until the fizzy smell is gone. You can finish the degassing with a drill in 3-7 minutes depending on the volume. The manual way takes much longer.

Warning! You can only clarify fermented washes, as adding acid stops the fermentation and all the sugars that aren’t recycled by the yeast go away. Pre-degassing increases clarification efficiency by 2-3 times.

Have you ever picked up a bottle of whiskey and noticed the liquid inside is cloudy? Or drop ice in a glass of whiskey only to see it cloud over? Don’t worry, this is not a defective product. It is whiskey that is not chill filtered and coveted by enthusiasts.

Unless it’s chill-filtered, any bottle of whiskey that’s diluted with water or left undisturbed at room temperature for a few hours will develop a cloudiness, says former Four Roses master distiller Jim Rutledge. “The vapor eventually turns into ugly, gross-looking solids in the bottle,” he says.

In fact, confused consumers often return those cloudy bottles to the store, says Jefferson’s bourbon founder Trey Zoeller. “As much as I love non-chill filtration, it’s a pain. People find floaters and are unhappy,” says Zoeller. Faced with this problem, most distillers simply choose to chill the filter before bottling.

Chill filtration prevents whiskey from developing haze but can also take away flavor if not done carefully. Former Heaven Hill master distiller Denny Potter explains that chill filtration removes fatty acids, esters and proteins that produce the haze also known as ‘chill floc’ F, forces the whiskey to flocculate and passes it through pressure leaf filter media walk,” says Potter. “This medium removes the cold flakes without changing the color or flavor.”

Some distillers lower the temperature to as low as 10°F during the chilling process, while others use carbon filtration to remove the flakes. But there is a compromise for such a crystal clear whisky; Potter claims that charcoal filtration also removes flavor. Rutledge notes that today’s connoisseurs prefer their whiskey not to be chill-filtered because it reassures them that the flavors have not been removed.

Distillers like MB Roland founder Paul Tomaszewski are staunch advocates of non-chill filtered whisky. “Non-chill filtered whiskey has an intimacy, an added warmth and depth,” he says. “The flavor profile adds layers and is just as bold and untamed as if you’re pouring straight from the cask, which is essentially what you are.”

How to tell if your whiskey is non-chill filtered

Many non-chill filtered whiskeys will announce it on the label. But if you’re unsure, these simple tests can help determine if a whiskey has been filtered for aesthetic reasons.

Shake it up: Swirl the bottle and watch closely as the whiskey trickles down the inside of the neck. Tomaszewski says whiskey that is not chill-filtered often has a cloudy residue.

Fuggedaboutit: According to Tomaszewski, an unchill-filtered whiskey left in a glass overnight will become opaque.

Put in the cold: put the bottle in the freezer. “If you don’t see any cloudiness once the temperature of the liquid drops below 30°F, that’s probably a good indication that the whiskey has been chill-filtered,” says Potter.

The Burden of Proof: According to Rutledge, higher proof whiskeys make chill filtration more difficult to identify. “The more water that’s added to a whisky, the faster the precipitation occurs, so there’s a greater risk of fatty acid precipitation with the lower alcohol content whiskeys,” he says. “I have never seen cloudiness in cask strength whiskey, no matter how long a bottle has been left undisturbed.” Dilute spirits at spirit with water before testing.

The glass on the left is non-chill filtered whiskey at ambient temperature and the glass on the right is the same whiskey with an ice cube added. So why do some whiskeys turn cloudy and others don’t?

The presence of natural fatty acids, esters and proteins in whiskey will cause it to become cloudy as it cools. They are derived from the barley and persist through distillation, but some are also transferred from the casks during aging. These fatty acids, esters, and proteins are soluble in alcohol but insoluble in water, and so upon cooling (or when you add ice!) they clump together as micelles (a spherical arrangement of lipid molecules due to their polarity), giving the cloudy appearance.

People unfamiliar with this phenomenon might think they have an inferior or flawed whiskey and be perceived as a ‘fault’ by many uninformed consumers. As such, it is often removed commercially to enhance the lustrous golden appearance we associate with whiskey. This is done through a process called chill filtration, which lowers the temperature of the whiskey to 0ºC for single malts and -4ºC for blends. The grain whiskey in blends usually has a lower natural concentration of fatty acids and the lower temperature helps with removal. The chilled whiskey is then forced through a series of compact metal screens or paper filters under pressure to remove the cloudy residue.

Whiskeys above 46% ABV (alcohol by volume) do not require chill filtration as the higher alcohol content prevents haze formation. But an unfiltered whiskey at 46% ABV or less will cloud when water or ice is added and when the whiskey is chilled. The solubility of the turbidity particles is not only dependent on the temperature, but also on the ethanol concentration.

Finally, the most important question – is there a difference in taste between chill-filtered and non-chill-filtered whisky? This is quite a controversial subject and is often not mentioned or disclosed on whiskey labels. But if you’re looking to shell out $60 for a bottle of single malt whiskey, consider this. According to a study by German scientist Horst Lüning, no significant difference was found between chill-filtered and non-chill-filtered whiskey. (In case you want to read more – https://www.whisky.com/information/knowledge/science/study-on-the-chill-filtration-of-scotch-single-malt-whiskies.html ) Some experts argue against it that filtration changes the taste and mouthfeel of whisky, but in reality it is difficult to compare as not many distilleries release the same batch of whiskey in chill-filtered and non-chill-filtered form. Whether you like your whiskey cask strength or chill filtered, drink it before the ice melts!

Why is my gin cloudy?

Gin becomes cloudy due to a phenomenon known as louching. Here the alcohol (a solvent) is no longer strong enough to keep the oils (the flavorings) dissolved in the solution. The oils then precipitate, resulting in a white, milky liquid. This can be due to a drop in temperature or the addition of water.

The backstory

Before we delve into the intimate intricacies of gin clouding and sucking, let’s first delve into the fascinating history of one of the most popular alcoholic beverages of all time. As a long-time bartender and spirits enthusiast, the ever-popular gin and tonic with a lime is perhaps one of my favorite drinks, and later on, I sip origin stories.

Although many historians credit Holland as the original inventor of gin and Britain as its primary producer and consumer, India is most credited with creating a classic cocktail of all time, the gin and tonic with lime. In the 1700s, during the British colonization of India, Indian sailors loaded cask after cask of gin onto their boats before setting out on their voyages, unsure of how much to bring.

Throughout the 17th century, particularly in India, there was a great deal of concern about the dangers and risks these sailors were taking in order to potentially contract one of the most widespread and deadly diseases of the day, malaria. The most effective treatment for malaria was thought to come in the form of a substance called quinine extracted from the bark of the Andean fever tree. However, it quickly became apparent that quinine was very bitter and almost impossible to ingest on its own, so it was extracted and mixed into what we now know as tonic water.

The longer these sailors were at sea, the more gin they drank, for moral reasons, of course. Unfortunately, these sailors soon found that they were quickly running out of gin and, after sailing for a while, were almost dry. In a desperate bid to stretch rations, and for the safety and well-being of the crew, the captains began ordering the crew to mix the remaining rations of gin with the quinine, as well as adding an old pirate trick, limes, to combat them Vitamin C deficiency disease, scurvy. When the sailors got safely to shore, a drink was born.

Though diseases once so devastating as scurvy and malaria aren’t quite as common today as they once were, the novelty of the drink and the gin drinker hasn’t changed much. You just got more options.

Why does my gin go cloudy when I add tonic?

You may be wondering why does a clear, transparent liquor like gin suddenly turn cloudy when tonic water is added? This drink mysteriously becomes cloudy when ice or tonic is added because the oil solubility in gin (the measure of how much oil will dissolve in water at a given temperature and pressure) decreases and the once clear and transparent liquid in turned a dull white. In a distilled spirit such as gin, the aromatic compounds or oils found in the botanicals such as juniper berries, lemon peel, and orange peel are absorbed by the spirit in which the botanicals are steeped or evaporated, ultimately leaving trace amounts of these oils associated with the Giving much of the flavor to gin.

Is cloudy gin safe to drink?

Cloudy gin is generally safe to drink and is just a testament to the oils used to flavor the spirit. The cloudiness is almost a good thing, as it proves that what you’re drinking is actually gin or some other spirit that gets its flavor from the distillation of botanicals or other oily flavors.

Now that we’ve covered the basics and cleared up a common question, it’s time to take that knowledge a step further and introduce the gin maker.

Why has my gin turned cloudy when I dilute it?

Most distillers don’t cold filter their gins. However, it is important to distinguish what exactly this process entails. Chill filter is a filter process that cools the gin to around 0 degrees Celsius. This process, in turn, filters out the liquid to remove any extraneous or interfering particles. The problem with the chiller filter method, however, is that most of these offending particles are just the essential oils of the botanicals used in the distillation process. While the chill-filter method of storing and drinking gin is sometimes a standard, mostly cosmetic industry practice, many seasoned gin distillers and drinkers prefer their gin undisturbed and served at or around room temperature. Because the greatest pleasure of a beautiful fine gin comes from the added essential oils, as this is where most of the work, creativity and originality comes from. It’s often the case that most drinkers are trained to drink only clear liquids, so it’s understandable that someone would have some apprehension about their gin being cloudy. But at the end of the day, all it means is that the essential oils present themselves in your jar and there is nothing to worry about.

what is punch

Louching is the official, or more technical, term for when a clear spirit like gin goes from clear to cloudy, milky, or opaque. When water is added to the gin, it instantly turns the gin from clear to cloudy. The more the gin is diluted with water, the greater the chance that the essential oils from the botanicals will come out of suspension and discolor the gin. The type of plant substances used also influences this. The botanicals with the higher oil content, as they begin to be diluted from the concentrate, create a greater likelihood of the gin going bad.

Is sucking a bad thing?

No, gin louching isn’t a bad thing, it’s more a matter of style and taste. Some people, mostly the occasional drinker, can sometimes think sucking looks suspicious, or rather they’ve been trained to see liquid clarity as more appealing and sucking as dirty, but that doesn’t mean there’s anything wrong with the drink is.

How to correct gin louching?

During the initial distillation, the still can make what is known as a “larger head cut”. That is, once the spirit begins to pool in the still, collect the first portion that comes out and discard it. There are many oils at the beginning of the distillation process because the still takes some time to heat up, so the first fraction is distilled many times, and when the vapor hits a cold part of the still, it turns back into a liquid and gives its way energy to heat the still. This process results in a high concentration of early juniper oils that need to be cut or discarded lest they overwhelm the gin. Another thing that can be done is “an earlier tail cut”. Here the distiller does not collect as many heavy oils at the end of the distillation, leaving the distiller with less gin concentrate overall. Diluting the product with less deionized water also corrects gin loching and prevents it from occurring in the first place.

Have you noticed that one or more batches of moonshine come out of the still with a bluish tint? It’s no secret that moonshine should be crystal clear with no impurities. For this reason, experienced moonlighters distil their drink multiple times to purify the contents. However, if the moonshine comes out with a bluish tint, then of course you can worry about what is causing the color change. In this post we will reveal what causes this phenomenon and whether or not it is safe to drink.

Copper Stills and Blue Moonshine

Copper is the material of choice for moonshine stills. Almost every experienced moonshine producer uses copper for their pot stills. Not only is it easy to find, but copper is resistant to contamination and possesses high heat transfer properties. However, copper can also cause moonshine to come out with a bluish tint if not used properly.

Why do copper stills produce a blue colored charge of moonshine? Although not always the case, moonlighters using copper stills can occasionally experience a blue batch. Basically, this is caused by the alcohol vapor corroding the copper metal. As the copper is literally eaten away, fragments get into the Moonshine charge, eventually giving it a bluish tint.

It’s important to note that moonshine made from fruit tends to turn blue. The highly acidic content of the fruit juice causes the copper pipes to corrode faster than normal. If you frequently experience blue bursts of moonshine, avoid using fruit in your porridge.

Can I drink blue colored moonshine?

I’m sure some people have drank blue colored moonshine without experiencing any negative side effects, but this is something you should try to avoid. To be on the safe side, avoid drinking blue moonshine that comes out of your still. I know this is difficult for some people, but you should dump your blue moonshine and throw away the used mash or wort. The copper residues and chemicals that cause the blue color are likely contaminating these ingredients as well. Throw it away and start over just to be on the safe side.

Cleaning your still both before and after a batch reduces the likelihood of bluish moonshine. Run some fresh spring water through your still and scrub it off with a sponge and baking soda. This should help remove loose material and debris on the pipes.

The cloudiness of certain absinthes is due to the addition of water. Spirits such as rum contain water-insoluble components (mainly fennel and star anise) and come out of solution when hydrated with the alcohol, making the drink milky and opaque and cloudy.

Why does alcohol make water white? Water imparts whiteness to ouzo and absinthe through the louche effect. The scientific basis for this is that adding essential oils to water tends to turn the liquid white. It does this by reacting the water with a “hydrophobic” chemical.

Which alcohol turns white with water? In water, absinthe turns into an iridescent white cloud when mixed with water. Yellowish-green liqueur flavored with herbs.

Why does rakı turn white when you add water? Outzo is an oil-in-water emulsion created when water is mixed with Ouzo and other anise-flavored liqueurs and spirits such as Pastis, Rak*, Arak, Sambuca.

Can absinthe be white? Bleue Absinthe is crystal clear and comes straight from the distillery after distillation and reduction. Shortly before bottling, it is distilled and reduced. It is a blanc that turns into green absinthe (“green” in French, sometimes called la fée verte).

Why does raki turn white with water? It is customary to add ice cubes. The milky white color of Rak* comes from dilution with water, just like the louche of absinthe. Because of this phenomenon, the drink is now known as Aslan sütü (lion’s milk).

Why does alcohol make water white? In the presence of ethanol, water causes the fat to emulsify, giving it its characteristic milky color.

Why does alcohol become cloudy? A batch of spirits heavily loaded with tails will turn cloudy once distilled. It is also interesting to note that at lower concentrations, spirits can appear clear at first, but appear cloudy after cooling.

Why does alcohol turn cloudy when water is added? The louche effect results from the fact that alcohol and water both have relatively similar pH values. Therefore, the louche effect is most affected by temperature, as colder absinthe will cloud faster than warm absinthe. The effect of louche becomes more apparent as more water is added.

Can water spoil alcohol? Drinking water dilutes alcohol in the body, while food slows the absorption of alcohol. It is also imperative that the person stop drinking immediately. The process of sobriety takes about an hour per alcoholic beverage consumed.

Why does Pernod become cloudy with water? What makes Pernod cloudy when you add water, and what would happen if the earth stopped spinning? ? The “ouzo effect” occurs when water is added to pastis, altering the delicate chemical balance and altering its appearance.

Why is Sambuca turning white? Sambuca has hydrophobic (water incompatible) oils dissolved in it as it is a mixture of ethanol and water (a more hydrophobic solvent).

What color is pure absinthe? A true absinthe is green In most cases, you shouldn’t judge a spirit by its color, but it can give you some clues. Chartreuse yellow and chartreuse green are the most common colors in craft absinthes, but clear absinthes are also available.

How does white absinthe taste? The taste of absinthe can be described as the taste of black liquorice mixed with a slight smell of herbs. It has primary flavors of anise, liquorice and herbal complexity, making it taste like more than liquorice candy. According to The Wormwood Society, the main flavors of absinthe are aniseed and liquorice.

I still remember my first encounter with absinthe. I was at a friend’s rooftop party on a beautiful day when he pulled out a neon fluorescent bottle out of nowhere and proudly challenged only the most daring of our group to try a shot of the Green Fairy.

Fast forward a few years, and I’ve gotten quite a taste for the herbaceous, complex, and deceptively high-proof spirit. The worst versions smell like liquorice and taste like cough syrup, but many good brands worth trying are now populating store shelves.

If you’ve tried absinthe, you know that while it’s perfectly acceptable (albeit a little intense) to drink the spirit neat, most fans of the stuff prefer to add a little water before drinking. Just like whiskey, water in absinthe can soften harsh edges and even cause aromatic compounds to become more volatile (and therefore tastier).

When you add water to whiskey, the liquids mix and swirl in the glass, but they eventually settle into a uniform blend that is visually almost indistinguishable from the original high proof pour. Add water to absinthe (or ouzo, or several other anise-flavored spirits) and something strange happens: the drink suddenly turns milky.

The Louche: what gives?

I never really thought that this cloudy effect – called louche – was anything particularly remarkable. In fact, if you’ve ever taken chemistry in high school, you’ve probably seen a similar effect practicing titration — adding one liquid to another drop by drop.

If you’ve been titrating in class, or if you’ve added water to absinthe, you may have seen the sequence I illustrated above. The target liquid is initially clear because everything is in solution. If you add a second liquid, a cloudiness will begin to form. That’s because you changed the balance in the system by adding a new player, and suddenly other chemicals don’t want to stay in solution anymore.

As I wrote in relation to fat-washing spirits, alcohol can dissolve both polar (water-loving) and non-polar (oil-loving) molecules. Since aromatic essential oils are non-polar, they can be hung dissolved in alcohol. However, add some truly polar water and the essential oils aren’t so happy and start to come out of solution.

Easy enough right? This is where it gets interesting.

Note the third image in the image above, labeled Precipitation. When a solution becomes cloudy, it’s usually due to chemicals leaching out of the solution. Eventually, these chemicals completely separate from the original solvent. Think of it this way: shake the oil and water very hard and it turns cloudy. However, let it sit for a few minutes and the oil and water will eventually separate. Likewise, you mix coffee grounds with water and the coffee stays cloudy in your French press for quite a while. Let it sit, however, and eventually these bottoms will settle to the ground.

This is how the world of solubility and precipitation works.

Except, my friend, in the case of Absinthe Louche.

As it turns out, when you add water to absinthe, the resulting cloudy mixture stays cloudy and won’t separate further for months. It’s about as weird as throwing a handful of sand into a swimming pool and the pool would be cloudy all summer long.

I don’t just make this stuff up and it wasn’t even cocktail nerds who got upset about it. Scientists call the louche phenomenon the “ouzo effect,” after the popular Greek anise-flavored spirit. Here are some selected quotes from a recent scientific summary of the phenomenon:

…the general belief is that the ouzo limit cannot be explained by classical equilibrium thermodynamics…

…In this context, the definition of “phase diagram” becomes ambiguous…

…the ouzo effect is a versatile way to form nanometric droplets of liquid enclosed in a protective shell…

What they want to say I think is “OMG you broke physics” and also “Your cocktail is nanotechnology”.

I’ve looked through some other literature on the ouzo effect, and as far as I can tell, the phenomenon results from the unique properties of anethole (the essential oil responsible for the aniseed flavor), high-proof ethanol, and water.

In normal situations, an emulsifier or extra energy (like mixing in a blender) is required to keep two normally separate liquids emulsified. For example, proteins in cow’s milk act as emulsifiers, while many nut milks require blending or shaking for the best texture. Researchers still don’t quite agree on why the combination of ethanol, water and some essential oils behaves differently – why an emulsion forms spontaneously without additional energy or an emulsifier.

From what I understand, the structure of the particular molecules in absinthe and other aniseed-flavored spirits allow energy to be transferred in such a way that a milky emulsion is eventually everyone’s favorite state. There are a few theories as to exactly how this works, with debates involving topics such as the “Marangoni Effect”, “Ostwald Ripening” and Brownian Motion all over my head. Regardless of the details, the effect is undeniably observable and repeatable. In fact, the paper cited above, as well as this paper, go so far as to coin a new zone in chemical solubility diagrams, dubbed the “Ouzo zone,” which could have novel applications in food science, nanotechnology, and drug delivery.

So the next time you drink absinthe (or ouzo, pastis, or sambuca), tell all your friends about the crazy science behind every bottle. Then again maybe not.

Vodka has long had a conflicting selling point: All brands promise their vodka is the best, but according to the government’s official definition of the spirit, vodka should be “without any distinctive character, aroma, flavor or colour”. So does that mean that the best vodkas have the least character, aroma, flavor and color? And if so, what the heck are consumers paying for?

A renewed interest in craft spirits — including craft vodka — has helped prove that claim false. Sure, vodka can have character, and not only connoisseurs have noticed that. The Alcohol and Tobacco Tax and Trade Bureau (TTB) also recognized that it may have misrepresented the neutral spirit. And since yesterday vodka is free – the new, changed vodka definition of the TTB officially comes into force.

The TTB’s identity standards used to be: “‘Vodka’ is neutral spirits that have been distilled, or treated after distillation with charcoal or other materials, so as to be without any distinctive character, aroma, flavor or color.” It was short and something ambiguous.

The new definition is both more specific and more comprehensive. “‘Vodka’ is a neutral spirit that can be treated with up to two grams of sugar per liter and up to one gram of citric acid per liter,” the revision begins. “Products intended to be labeled as vodka must not be aged or stored in wooden casks at any point, except when stored in paraffin-lined wooden casks and labeled as bottled in bond… vodka treated and filtered with at least one ounce of activated charcoal or activated charcoal per.” 100 gallons of wine spirits may be labeled as ‘charcoal filtered’.”

As revealed by the federal register, the official identity of vodka was already in the balance. The TTB wanted to change vodka’s “identity standard” as several federal decisions had already necessitated some adjustments. And apparently, since they were already planning to change this anyway, the TTB also “solicited an opinion on whether the current requirement that vodka should be without distinctiveness, aroma, taste or color should be retained and, if that requirement is no longer appropriate to what the appropriate standards should be to distinguish vodka from other neutral spirits.”

Funnily enough, the TTB said it received 12 comments – and a crucial zero of those had to do with its plan to align the definition with previous rulings. Instead, all 12 comments were about the whole tasteless thing, with 10 of those people saying it should go. TBB specifically highlighted a comment from Altitude Spirits stating that the requirement “is no longer appropriate given the variety of base ingredients, aromas and flavor profiles found in the diverse vodka category”.

Meanwhile, only two commenters said the definition should remain unchanged — suspiciously “without explanation,” according to the TTB. And interestingly, two of the commentators who wanted the definition changed believed that the TTB should go even further and finally allow vodka to be aged in wood.

“Based on reviewing the comments, TTB agrees that the requirement that vodka be devoid of distinctiveness, aroma, flavor or color no longer meets consumer expectations and should be removed,” the agency wrote in its decision last month . “Vodka will continue to be distinguished by its specific production standards: vodka may not be labeled as aged and, unlike other neutral spirits, may contain limited amounts of sugar and citric acid.”

Sometimes the older the alcohol gets, the better it tastes. But not all alcohol defies time like this. There are obviously a variety of types of alcohol, and each has its own lifespan that one needs to be aware of.

And each bottle’s mortality clock usually starts ticking when it’s opened. Opened alcohol can expire and spoil. And when it does, the most common effect is a loss of color, flavor, or both.

Keeping track of each alcohol’s shelf life is a crucial part of your bar’s inventory. That way, you won’t serve bunk drinks or bleed money while your bottles die unused. Before you even learn how to get an alcohol license, you should learn how to take care of your alcohol inventory.

Does alcohol expire?

Unopened spirits have an unlimited shelf life. Opened liquor lasts about a year or two before going bad, which means it starts to lose its color and flavor. Do not use fountain drink liqueur unless you use the entire bottle within two years. However, it does not generally become toxic.

As always, use common sense: if you see anything suspicious in your old liquor (like mold or something that’s floating), throw it out. Checking if your alcohol has expired is a valuable part of a bartender’s duties.

Why does alcohol go bad?

So what makes an alcohol bad? There are three main factors that can affect spirit quality over time: light, temperature and air.

Why is light bad for alcohol? Prolonged exposure to daylight can cause alcohol to lose its color. In the case of spirits, changes in color indicate changes in taste. Similarly, changes in temperature can break down an organic molecule called a “terpene,” which changes the flavor of the spirit. Finally, exposure to air can oxidize the liquid, affecting its taste.

That means if you store liquor at a moderate temperature away from direct light, it will last indefinitely. At 30% to 40%, alcohol is not a hospitable environment for bacteria. And when it’s not open, you have virtually no oxidation.

But as soon as you open a spirits bottle, oxidation begins. Because of this, most hard liquors will “spoil” within a year or two. But when we say bad, we don’t mean they mold, become toxic, or curdle. What we mean is that the amount of oxidation degrades the taste and quality to such an extent that you might as well not drink it. But you can if you want.

We recommend emptying the bottle (which is admittedly not easy with some liquor bottle sizes) as soon as possible after opening. Because once you open a bottle, time is not on your side. Keeping to the right standard pours and tracking the number of pours is a great way to avoid waste.

When does alcohol expire?

Does Unopened Alcohol Go Bad?

Most primary (aka “base”) spirits such as whiskey, brandy, rum, gin, tequila, and vodka have an almost indefinite shelf life if left unopened.

That’s because they don’t contain a lot of sugar and aren’t at risk of oxidation unopened. The high alcohol content also makes them particularly inhospitable to bacteria.

Do open liquor bottles go bad?

Once you open spirits bottles (primary liquors like vodka, gin, rum, whiskey, tequila, etc.) they lose certain flavor characteristics over the years. But they will not spoil. If an opened bottle of spirits is nearing its expiration date, you can always use it for happy hour and discount it. You should also try to sell drinks and avoid wasting more expensive top-end spirits.

It is important to note that the less alcohol there is in an opened bottle of liquor, the faster the alcohol will expire. This is because there is more oxygen-rich air in the bottle, which accelerates oxidation and degradation. Try to keep track of the alcohol left and make sure you know how many shots are in a hold.

Now let’s look at each type of ghost.

Does vodka go bad?

No, vodka really doesn’t go bad. If the bottle remains unopened, vodka can be kept for decades. So vodka practically does not expire.

Vodka is a simple, stable spirit. There’s just not much in it. So there aren’t many chemicals that start to break down and get out of control. But no bottle of vodka is perfectly hermetically sealed. There will be some contact with the outside air.

After about 40 or 50 years, an unopened bottle of vodka may have lost enough flavor and alcohol content to be considered expired due to slow, even oxidation. But it could also take 100 years. The point is, for our purposes, vodka doesn’t expire, but it wouldn’t literally last forever.

Once opened, there aren’t many changes. Vodka is a long-lived spirit. The shelf life of opened vodka is about 10 to 20 years. After opening the bottle, the seal is weaker and oxidation is relatively quick. We’re still talking decades until vodka expires, which is why we say not much is changing.

Does whiskey go bad?

Unopened whiskey does not go bad. Unopened whiskey has an unlimited shelf life, but whiskey can expire. You just have to open the bottle.

Most whiskey scientists believe that an opened bottle of whiskey lasts around 1 to 2 years – when half full. Whiskey expires approximately 6 months when it is a quarter full or less. Because the less whiskey in the bottle, the more oxygen it contains. And the more oxygen, the faster the oxidation and the faster the whiskey can spoil.

Does bourbon go bad?

The shelf life of bourbon is not that different from the shelf life of whiskey overall.

A bottle of bourbon doesn’t go bad unopened. You can store it for decades. But once a bottle of bourbon is opened, it takes about 1 to 2 years to go bad. Again, this time frame depends on the amount of whiskey in the bottle.

Does rum go bad?

An unopened bottle of rum doesn’t go bad. Unopened rum can last for decades and decades. But once the bottle is opened, rum goes pretty fast. Seaspirits Distillery, master rum distillers, recommend drinking a bottle of rum within 6 months of opening. There are worse fates.

Does tequila expire?

Tequila does not expire if left unopened like the other ambient spirits. But tequila can go bad.

Once opened, tequila should be enjoyed within a year. How long does tequila last?

Does gin go bad?

Gin can go bad if not consumed within a year or so of opening the bottle. If kept sealed, a bottle of gin can last indefinitely if stored away from direct sunlight and not extreme temperatures.

Unlike vodka, gin relies on the subtle flavors of the botanicals. That means gin has a lot more to lose when it comes to flavor loss. Because of this, gin’s shelf life in open bottles is a fraction of that of vodka, but both are clear spirits.

Does brandy go bad?

Unopened, brandy will not spoil if kept away from heat and light.

After opening a bottle of brandy, there is about 1 to 2 years before the taste and quality deteriorate noticeably.

Do liquors and liqueurs go bad?

Liqueurs and liqueurs like Grand Marnier, Drambuie and Midori will spoil much sooner. That’s because they contain sugar and other volatile ingredients.

If you’re ever confused as to which bottle will expire the fastest, just look at the sugar content. The more sugar an alcohol has, the quicker it will deteriorate, especially if opened.

Many liqueurs and cordials, such as cream liqueurs, can spoil and become undrinkable after a year or more. Even if your bottle isn’t about to spoil, it’s best to store it strictly according to storage guidelines. If opened, they can lose their flavor within a few months.

Check the bottle to see if there are any preservatives. This can help stem the tide of ruin. There may even be an expiration date on the bottle, which is always helpful.

But if you ever see discoloration or buildup in the bottle, it’s best to throw it away. You can give it a quick taste test if you want, but chances are it won’t meet your standards.

Can wine go bad?

Yes, wine can go bad, but many factors play into how bad it goes and when it goes bad. Wine storage conditions, the type of wine, whether it has been opened and how long it is stored. The following times are based on the correct wine storage temperature and wine cellar lighting.

How long does wine keep unopened?

In general, red wine, which retails for around $10-30 in stores, lasts around 2-3 years unopened. Likewise, unopened white wine of similar quality will last around 1–2 years.

You may not want to buy a full case of wine unless you’re going to use up the bottles quickly. If this conflicts with what you’ve heard about aging wine for decades, that’s by design. Wines in these price ranges are designed to be enjoyed straight out of bottling. If a wine is meant to age, that’s built into the winemaking process.

If you are into fine wines that are meant to be aged, they can last for decades unopened. Both red and white wines, although fuller bodied and red wines tend to age better. The best thing you can do if you’re serious about aging wine for years is to figure out the optimal storage conditions and times for that particular wine.

Alcohol-free blenders

For alcohol-free blenders and other perishable items, we recommend adhering to the expiration date printed on the bottles. You often need to keep these in the fridge after opening as well, and it says so on the bottle too. This includes juices.

The ones with the shortest lifespans in your bar are most likely sodas and sparkling water. As anyone knows from their life with fizzy drinks, this stuff doesn’t last long. Use the fizzy stuff as soon as possible after opening.

Because these mixers are part of most popular cocktails, it’s important to make sure they don’t go bad.

Frequently asked questions about the alcohol expiration

Does beer go bad?

Most beers last longer than the expiration date printed on the packaging. If stored at room temperature you can expect beer to last 6-9 months past the expiration date. When stored in a cool place, this period is extended to up to 2 years.

How do you know if the alcohol has gone bad?

You will know if your alcohol has gone bad if you notice a change in color or smell, although this is uncommon.

Can you drink expired alcohol?

After a bottle of alcohol has expired, it’s okay to drink, but the alcohol content will be reduced.

So does alcohol expire?

Yes, your alcohol can go bad. Fast, too, if you are not careful enough when storing. Because of this, it’s important that your bar purchases liquor in the correct quantity and stocks the bar with a full bar liquor list, taking into account usage and denominations.

You also need to store your spirits properly if you intend to sell them through selling spirits online, especially if you are shipping alcohol long distances.

Like everything else in your bar, your alcohol has its own expiration date that you need to be aware of. Always know how many beers are in a keg so you know when you’re running out of keg and not pumping a flipped beer.
