When it comes to your ideal drinking situation, would you prefer your favorite drink to be as good as possible or mild and tasteless? We bet the answer is pretty obvious.

An essential component for the best taste is the material from which the mug is made. Although there are many different types of drinking vessels, from plastic to metal to paper, the material you choose will affect the flavor of your coffee. This is why ceramic coffee mugs dominate the taste test and are clearly superior to alternative materials.

Why does coffee taste better from a ceramic mug?

The first thing to know about enjoying a drink is that presentation plays a crucial role in how the drink tastes. There are many studies proving that presentation affects taste, and you’ve no doubt experienced it firsthand. Every time you go to a restaurant, the food doesn’t just plonk onto your plate. It is carefully arranged and organized, which better represents a quality and flavorful meal. Like ceramics for coffee.

It’s human nature to perceive quality in context, and using a ceramic mug usually means you’re enjoying a more comfortable environment. Compare it to a paper cup. From where you use it (home, office, at a local coffee shop) to where you go, drinking from ceramic coffee mugs feels like a better experience because of the associations you make with your mug their weight, texture and insulating properties. On the other hand, a paper cup is temporary and disposable and will most likely be used in new settings or unique situations like an out-of-state business meeting.

While perceived taste quality is important, there is also objective improvement. For taste, ceramic is the best choice. Why does coffee taste better from a ceramic mug? Because ceramic is a solid and neutral material, it neither absorbs nor releases aromas, so the coffee tastes exactly as it should. Our sense of taste is complicated, to say the least. For one thing, the flavor characteristics cannot simply be narrowed down to sweet, sour, salty, and bitter. Much of what we think of as taste is really smell – so ceramic, with its neutral properties, really is the best choice.

Other types of cup materials

There are many other types of mug materials, but why don’t they taste as good as ceramic? Let’s examine some of the different types of mugs and what they are made of.

plastic

Plastic might seem like a good choice due to its light weight and convenience, but over time the material actually absorbs odors and flavors, making your coffee taste bad. It’s probably not a big deal if you only drink one type of liquid from your plastic cup, but even different types of coffee can get absorbed into the porous plastic and your drinks will taste bad over time.

paper

Arguably the worst way to drink coffee is from a paper cup. When you heat paper, especially treated paper that a coffee cup is made of, it can start to smell. This will surely interfere with an ideal drinking experience.

What’s more, not only does coffee taste better from a ceramic mug, but it’s also a much more sustainable way to enjoy your drinks.

Stainless steel

While stainless steel is extremely durable and good for outdoor trips, it can add flavor to your coffee. It doesn’t absorb flavor, but since many companies use cheap materials, surfaces can slowly leach into the drinks. Also, there are more than 1,000 compounds in coffee that can react oddly with metal, so you could end up with some odd-tasting notes.

Glass

While glass also offers a neutral taste similar to ceramic, it’s not quite as good at providing the optimal coffee experience. Because ceramic retains heat better than glass, your coffee will stay warm much longer. And because coffee changes flavor as it cools, you can enjoy the deliciousness longer by keeping it as hot as possible.

Social media users have shared posts advising drivers to pour hot water on their car’s windshield to defrost it faster. This claim is wrong.

Reuters fact check. REUTERS

Examples can be seen here and here.

A post here says, “Pour hot water on your windshield and it will defrost faster, thanks later.”

A winter storm hit the United States this week, leaving normally warmer states unprepared for the cold. The weather has closed COVID-19 vaccination centers and hampered vaccine supplies (here).

The American Automobile Association (AAA) and Automobile Association (AA) both advise against using hot water on a windshield because the glass can crack or shatter due to the sudden change in temperature (here, here).

Instead, the AAA recommends starting the engine, setting the heater to “defrost,” setting the airflow to recirculation, and setting the temperature control to full heat. When the ice melts, drivers can use a plastic scraper, windshield wipers, a squeegee, or a soft brush to remove the ice from the glass (here).

Glass companies across the country also advise against using hot or warm water on windshields in cold temperatures (here, here, and here).

VERDICT

NOT CORRECT. Pouring hot water over a car’s windshield at low temperatures can damage it and cause it to crack or shatter from the sudden temperature change.

This article was produced by the Reuters Fact Check team. Read more about our fact-checking work here.

At what temperature does glass break? Glass bottles and jars are not normally affected by ambient, refrigerated or warm temperatures. However, high heat (>300°F) and excessive thermal cycling can cause glass to chip or shatter. Glass is a poor conductor of heat and rapid changes in temperature (approximately 60°F and above) can cause stress cracks in the glass, which can eventually crack. When heated, thin glass begins to crack, typically breaking at 302–392 °F.

When a glass container is placed on a very hot heat source (e.g. 500°C), it can gradually lose its shape, going from a permanently solid form to a plastic state.

In general, glasses should not be heated in the microwave or oven. Ordinary glass jars can break or explode in the microwave. Some glass containers are made of heat-resistant materials and can withstand microwaves. Consumers can find the “Microwave Safe” mark on the bottom of glass products intended for use in microwave ovens. However, when heating glass containers in the microwave, secured lids should never be used.

Glass can break when exposed to freezing temperatures. This can happen because the contents freeze and its expansion causes the jar to break (if the cap doesn’t come off).

Why does hot water break? It is not the hot water that breaks the glass, but the sudden change in temperature that exerts internal stresses on the material. If these changes occur suddenly, they create internal stresses that lead to the rupture of the container. Glass is a poor conductor of heat and therefore does not tolerate excessive temperature fluctuations. Normally it tolerates around 45 °C. So, for example, if the application requires a temperature of 90ºC for pasteurization, it is necessary to gradually increase the temperature of the environment in which the container is located. This method avoids problems even with the sterilization process that reaches 130°C. Specially shaped containers (handled glasses, sharp edges, oversized containers, etc.) require an even more step-by-step process.

Why do some bottles bounce off the ground without shattering after falling from a great height while others shatter? Whether or not a glass container breaks depends not only on the type of impact, but also on the thickness and distribution of the glass and the degree of hardening.

What does “shatterproof glass” mean if the glass then breaks? This is a “current” term that is not entirely accurate. It refers to glass that has undergone a specific process called “tempering” that brings the object to a temperature of around 600°C and then suddenly cools it (with cold air distributed according to the thickness of the glass), resulting in controlled increased tensions arise within the object. In practice, a layer of tensile stress is created, bounded by two layers of compressive stress, giving the object increased resistance. The resulting molecular structure allows the glass to shatter into very small particles in the event of a strong impact, which cannot cause any damage.

You have selected your favorite origin from your favorite roaster, bought your coffee and brewed it perfectly. It seems like there is nothing left but to pour it into a mug and enjoy.

However, choosing the right vessel – and the right material – is more important than you might think. In order to be able to enjoy your cup to the fullest, you should make sure that the material you choose does not negatively affect the taste of the coffee.

To find out how some of the most common materials can affect the flavor of your coffee, I spoke to Silvio Chang, a certified Q-Grader and co-founder of Unseen Select Co.

Why material is important

Most takeaway coffees are served in disposable cups. In the UK alone, 2.5 billion of these are used every year. Its production uses an estimated 1.5 billion liters of water. While many of these cups are recyclable, only 1 in 400 ends up being properly recycled.

Consumers around the world are more aware than ever of the impact their purchases have on the environment. As a result, many people are switching to reusable options. But which material is best?

While preferences vary, there are a few key things that make a coffee drinking material good. Ideally, it should be lightweight, durable and retain heat well. It’s also important that it doesn’t affect the flavor of your coffee by trapping lingering aromas in the material itself or creating its own distinctive, undesirable flavor.

We compared four of the main materials used to make coffee mugs — glass, stainless steel, reinforced plastic, and ceramic — to see how each affects the flavor of a cup of coffee.

Glass

Few materials are as visually appealing as glass. It’s elegant and attractive, and you can enjoy looking at your drink as you consume it.

If your mug is made of tempered, heat-resistant glass, it won’t splinter or break no matter how hot your coffee is. If you choose a double-walled glass mug, it’s also comfortable enough to carry in your hand anywhere. Glass is also generally very easy to recycle.

Silvio says that while glass cups don’t affect the flavor of the coffee, “they don’t retain heat as well as ceramic cups.” Since the temperature of the coffee affects its taste, you should take care to keep your coffee hot but not over-brewed while you drink it.

Research shows that flavors and aromas are harder to detect below 50°C, which means you want to keep your coffee above that threshold for as long as possible.

Tempered glass mugs and mugs are also often more expensive than ceramic, plastic, or steel mugs. And while glass mugs look great in the kitchen or coffee shop, it’s a less-suited material for people who want to take coffee with them on the go.

Stainless steel

Stainless steel is practically indestructible. Unlike glass, it retains heat well because metal is a natural conductor of heat. It’s also relatively easy to clean.

Although it can be visually appealing, grease and fingerprints will show up very easily on stainless steel.

Stainless steel also has a strong metallic taste that can affect the taste of your coffee and other beverages. Although this will not wash away, it may fade with time and use.

Silvio notes that while stainless steel is generally very strong, it becomes porous over time. This means it absorbs residual oils from the coffee you drink from it, causing it to take on specific flavors and smells over time.

He adds, “The acidity in coffee can cause stainless steel to break down over time, releasing microscopic particles of potentially toxic substances like nickel.” While this probably won’t pose a major health concern for most people, Silvio does recommend that people only use stainless steel cups and bottles for water instead of coffee.

plastic

Because it’s cheap and easy to manufacture, reinforced heat-resistant plastic is often used to make coffee cups, bottles, and mugs. While plastic isn’t as strong as stainless steel, it’s good for hot coffee.

However, plastic cups are often less durable than cups made from other materials, such as plastic. e.g. stainless steel.

In addition, over time, plastic can absorb unpleasant odors and aromas that affect the taste of your coffee. Silvio says: “Even if you don’t notice it the first time, you will eventually notice that your coffee tastes different.”

Finally, plastic is also notoriously bad for the environment and can be difficult to recycle in some regions. Even if you buy a plastic cup and reuse it multiple times, it can end up in landfill.

pottery

Ceramic drinking vessels are very popular because they are cheap, light and retain heat well. They also don’t affect the taste of the liquid they contain, making them ideal for coffee.

Ceramic mugs are also generally leak-proof and hold their color and design well. Silvio says, “Ceramic is still the best option when it comes to coffee” as it has all the positive qualities of other materials without the disadvantages.

“It’s eco-friendly, but it’s the same as stainless steel, which is also non-porous and heat-resistant.” The different qualities of ceramic drinking vessels prompted Silvio to introduce the WOKY bottle to a wider market.

Silvio says that with the WOKY “you get the best taste from your coffee, you can carry it around and it stays hot”. Because it’s all-ceramic, it won’t affect the flavor of your coffee and is safe for dishwasher and manual cleaning.

“The WOKY bottle is the first on the market to be made entirely of ceramic; It’s not just a ceramic liner. A lot of bottles use a ceramic coating that peels off, or stainless steel as part of the mouthpiece,” Silvio tells me. He adds that since the bottle is made entirely of ceramic, it can also be used and reused for juice, milk, tea or even fizzy drinks.

“We see that there are many stainless steel thermos bottles on the market and many people use them for their coffee. But you also hear a lot of people complain about a “strange metal taste” and how difficult it is to clean up afterwards.

“With WOKY, we have completely combined your favorite coffee mug and your travel thermos flask.”

To fully enjoy your coffee, you need the right tools. This includes everything from brewing to drinking the end product.

There is a whole range of materials to choose from. While some are more visually appealing or retain heat better than others, your priority should be choosing a sustainable option that will keep your coffee warm and tasting as good as possible.

The forms are variable, but the meanings converge on prototypes.

In 1973, Labov showed how this works with a cup and mug in a classic series of experiments.

Labow, Wilhelm. 1973. “Word boundaries and their meaning” in R. Fasold (ed.), Variation in the Form and Use of Language: A Sociolinguistics Reader. Georgetown University Press, 1983.

To summarize the relevant points, no, cup and glass are not the same in English. Yes, a plastic cup can be called a glass depending on the context.

Not all coffee mugs have to be chunky ceramic pieces bought as a souvenir or given as a gift at a corporate event. In fact, there are many design-oriented mugs out there. One of the most popular variants is the glass coffee mug, which gives you a crystal-clear view of your hot drink.

Yes, you can drink coffee or tea from a glass mug. But it can’t be just any glass – make sure any glassware you use for hot liquids is borosilicate glass, which is stronger and can hold hot liquids without breaking. Another consideration when buying a glass mug is that it is double walled. This will help insulate your drink so it doesn’t get cold too quickly. The rest really depends on your preferences – each mug is a slightly different size and style, so it totally depends on how much coffee you pour each morning.

You don’t have to use these just for coffee, either. The beauty of a glass mug is that unlike other, more chintzy coffee mugs, you’ll want to use it for other drinks as well. Here are four of the best on Amazon.

1. Eparé Glass Coffee Cups When it comes to glass coffee cups, you can’t go wrong with this set from Eparé. The 12-ounce duo has a double-walled design — great for keeping your drink hot and your fingers safe from burns — and is made from hand-blown glass. Its design also prevents condensation, so you don’t need a coaster when you put in some ice water. And because it’s made of borosilicate glass, it can take a beating and is perfectly dishwasher safe. Glass Eparé Coffee Mugs: $34.95

2. Brew to a Tea Insulated Glass Coffee Mug If you’re looking for a set of glass coffee mugs for yourself and other coffee drinkers in your family, then Brew to a Tea’s range is the best place to start. It includes four cups, each holding 16 ounces of liquid — more than any other cup on this list. Like any good mug, it’s made from borosilicate glass, so it can take a beating and won’t break. Plus, it won’t scratch or chip easily either, so it will look good for years to come. However, if you’re just looking for a cup or two, this package might be a bit over the top. Brew to a Tea Insulated Glass Coffee Mug: $39.99

3. Kitchables Coffee or Tea Glass Mugs If you want to deviate a little from the traditional coffee mug look, then the Kitchables pack is the way to go. It consists of two glass coffee mugs, both of which are slightly taller and slimmer than your run-of-the-mill offering. And they don’t sacrifice functionality either, as both can hold 15 ounces of coffee or tea, which is significantly more than the 12-ounce norm. Most importantly, they are very durable and can easily be put in the microwave or dishwasher. Kitchables Coffee or Tea Glass Mug: $29.99

There’s nothing like a hot cup of coffee in the morning. But if you’ve brewed too much, you might be wondering if you can put hot coffee in a fridge before heading to work.

In general, you can put hot coffee in the fridge for storage or cooling. However, it should be stored in an airtight container to prevent it from oxidizing or absorbing flavors from the fridge. Remember that coffee does not stay fresh indefinitely and should be used within four days.

While coffee tastes perfect in the fridge, what you intend to do with it is also important.

For example, if you need to store coffee for several days, it is best to use one type of container. However, if you just want to cool it down quickly, you’ll need a different container and methods.

Let’s take a look at each of these scenarios and see what your best options are.

Can you put hot coffee in a fridge?

It’s perfectly fine to put your coffee in the fridge as long as you keep it in a sealed, airtight container.

People usually ask this question because they are

I’m not sure what effect the fridge will have on their coffee

not sure if hot coffee can negatively affect their fridge or the food stored there

In both cases there should be no problems. But let’s look at each scenario individually to see exactly what’s going on.

Coffee that is not stored properly can lose its flavor quickly

One of the main reasons people put coffee in the fridge is to preserve its flavor.

Oxygen in the air breaks down the acids, oils, and sugars that give coffee its flavor and aroma. This is why coffee loses its flavor so quickly after brewing.

Storing your coffee in the fridge is one way to preserve the flavors, but of course there’s oxygen in the fridge too!

Because of this, you should seal your coffee in an airtight container to limit the oxidation process.

It’s best to get a glass jar with a lid to keep your coffee safe in the fridge. (We use Mason Jars, which you can find at local stores or on Amazon.)

Coffee can absorb flavors in the fridge if left unsealed

Coffee is known to absorb odors. And since many of us have refrigerators stocked with leftovers and other items, there’s a good chance your coffee will take on unwanted flavors if it’s not sealed properly.

But beyond that, you also want to use the right type of container to store your coffee.

For example, plastic containers tend to absorb odors that are very difficult to eliminate. And if you pour your coffee in plastic, any odors that cling to the container will end up in your drink.

In comparison, glass does not absorb odors, so there is no risk of your coffee absorbing odors.

Hot coffee won’t hurt your fridge

It is generally recommended not to put hot food in the refrigerator. You may be wondering if it’s okay to put hot coffee in the fridge.

When it comes to groceries, there are a few reasons you might not want to put them in the fridge:

hot food can significantly increase the temperature of your refrigerator,

There is a risk that the food will already be in your fridge and will be heated

Your device has to work much harder to bring the temperature back down

But a carafe of coffee won’t significantly affect the temperature of your fridge, so you don’t have to worry about any of these issues when putting coffee in the fridge.

How long does coffee keep in the fridge?

If you store it in a sealed, airtight container, you can expect your coffee to last up to 4 days.

By sealing coffee in an airtight container, you limit oxidation and flavor loss. But the fact is that water also contains oxygen. So, over time, the brewed coffee slowly oxidizes itself.

And after 4 days, many of the coffee’s acids, oils and sugars are broken down.

The taste of your coffee will deteriorate if it is reheated

One last thing to note is that reheating your coffee will degrade the flavor of your coffee.

While refrigeration preserves the flavor for as long as possible, the reheating process changes the flavor profile and chemical composition of the coffee

Break down aromatic substances in coffee

increase acidity

As a result, the coffee loses much of its original taste and becomes much more bitter.

However, if you really want to warm up your coffee, it’s best to heat it on the stovetop over low-medium heat. Essentially, slower heating results in fewer chemical changes.

What is the best way to cool down hot coffee?

The best way to cool down hot coffee quickly is to put it in an ice bath or add coffee ice cubes to the drink. Using any of these methods, your coffee should reach room temperature in about 10 minutes.

To find out, we tested different methods of cooling hot coffee. Namely:

Give coffee an ice bath

Adding coffee ice cubes to hot coffee

put hot coffee in the freezer

with a device like the Cold Wave Beverage Chiller

Our goal in these experiments was to take a cup of hot coffee and see how long it would take to reach room temperature.

Below you can see our results.

Pro tip: Stainless steel is a better conductor of heat than glass, ceramic, or plastic. So if you use a stainless steel cup, your coffee will cool down much faster.

Cool coffee with an ice bath

Cooling hot coffee with an ice bath takes about 10 minutes.

For this process you need:

hot coffee

a non-insulated mug (preferably stainless steel)

a bowl of ice and water

a spoon

We started by pouring freshly brewed coffee into the cup and taking its temperature (we use a probe thermometer you can find on Amazon).

We then placed the cup of coffee in a bowl of ice and water and let it sit for a few minutes, stirring occasionally.

After about 10 minutes we checked the temperature and found that it was colder than room temperature.

The ice bath method is our favorite method of chilling coffee quickly, but it has a downside. If you don’t have an automatic ice maker, you’ll need to freeze or buy ice cubes.

Using coffee ice cubes to cool brewed coffee

Cooling your coffee with ice cubes takes about 10 minutes.

However, this method requires you to freeze some coffee beforehand.

After brewing our coffee, we poured it into a cup and took the temperature.

We started by adding half a cup of ice cubes to the hot coffee. However, after about 5 minutes the ice cubes had melted but the coffee didn’t reach room temperature.

We then added the other half of the ice cubes and after a few more minutes the coffee was below room temperature.

In total, it took about 10 minutes for the coffee to cool down.

This is another quick way to cool coffee. However, the downside here is that it took a whole bowl of ice cubes to chill our coffee.

FYI: An alternative to using coffee ice cubes is to use reusable ice cubes. You can find reusable ice cubes on Amazon or at your local store.

Put your coffee in the freezer

It takes about 40 minutes to chill the coffee in the freezer.

To start, we poured freshly brewed coffee into our stainless steel pot and measured the temperature.

We then placed a spoon in the hot coffee to dissipate the heat from the coffee. And immediately put the coffee in the freezer.

After 10 minutes we checked the temperature and found that the coffee was still relatively hot. We then returned every 10 minutes to check the coffee and found that it had reached room temperature after a total of 40 minutes.

While putting coffee in the freezer is the slowest method, the upside is that you don’t need ice cubes, bowls, or frozen coffee.

If you’re not in a hurry to cool your coffee, this might be a good option for you.

Chill your coffee with a cold wave beverage cooler

Another option is to purchase a device like the Coldwave Beverage Chiller.

Here’s a short video showing how this device can chill your hot coffee in minutes!

The central theses

You can refrigerate coffee, but it should be sealed in an airtight glass container to prevent oxidation and aroma absorption.

You can chill hot coffee in about 10 minutes by giving it an ice bath or adding frozen coffee.

Trying to chill your coffee in the freezer can take up to 40 minutes.

There are devices like reusable ice cubes or the ColdWave Beverage Chiller that can chill your coffee quickly.

Cheers coffee lovers!

Best mugs for serving coffee

Coffee experts believe that the coffee drinking experience is greatly enhanced by the choice of cup/glass you choose. For example, Italians believe that the small white cup is perfect for an espresso. The white contrasts with the rich, dark coffee. Here is a list of our picks for the best coffee mugs.

We look at a variety of beverages and brewing techniques. You can read our article on types of coffee to remember the variety of coffee drinks. A kettle is a handy gadget to warm up the coffee cups.

If you have a lot of storage space in your kitchen, you can surely treat yourself to the best coffee mug for every coffee drink. If you’re short on space some of the drinks can easily be doubled and work just as well.

​Here’s our pick of the best coffee mug shapes illustrated so you can see what we mean.

Clicking on the image or the text below the image will take you to a shopping page.

1. Espresso cups (demitasse cups)/Café Bombon cups

Demitasse means half a cup and the espresso cup size is ideally between 60-90ml. White is the classic color for serving an espresso. There are some classic shapes – designed to let the intensity of the aromas and flavors reach your nose and mouth at the same time.

For a more contemporary look, glass and colorful mugs work well. The transparency of the glass reveals the espresso and its three components – crema, body and heart. If you want to taste the delicious Spanish café bombon, then glass cups are a must so you can see the layers of this coffee.

The real reason your coffee might taste different in a to-go mug

If you drink a cup of coffee at home every day, you know that the to-go mug you prepare for on the go just doesn’t taste the same. Blame the morning rush and lack of time that keeps you from enjoying your coffee at the leisurely pace you would at home if you are allowed, but there’s something about a coffee to go that just isn’t the same .

You could use the exact same brewing method for your to-go mug—using the same coffee beans, the same brewing time, the same brewing equipment, and even measuring the water temperature. However, the coffee in a to-go mug is a bit disappointing. If you are facing a similar problem, you are not alone.

A Reddit user asked a similar question a few weeks ago, after which another user said that Charles Spence, an experimental psychologist at Oxford University, has a scientific explanation for this strange problem. According to Spence, the number one reason coffee doesn’t taste the same in a to-go mug is because you can’t smell it. Considering how important smell is to the enjoyment of food and drink, the lid on your to-go mug prevents you from perceiving the coffee aroma, which you would normally do when drinking coffee from a mug at home.

Choosing a coffee mug is a very personal decision. While you might have a variety of mugs, chances are you have one that you prefer above all others. Typically, a favorite mug is an aesthetic matter, but there are other factors that can come into play when choosing a mug. If you are looking for a new favorite coffee mug, here are the glass and ceramic choices from a thermodynamic and ecological point of view.

Ceramic retains heat better than glass

When it comes to keeping your coffee warm, ceramic outperforms glass. In addition to heat loss through evaporation, which depends on the shape of the mug and the surface area of ​​the coffee exposed to air, your coffee cools as the mug itself extracts heat through conduction and loses it through convection. In both areas, ceramic loses heat more slowly than glass.

Conduction is heat loss through the direct contact of two materials, one of which is colder than the other. Because ceramic is more porous than glass, conduction in ceramic mugs occurs more slowly. The small air pockets trapped in the ceramic act as insulators and slow down the conduction process.

Convection is heat loss through contact with air. Once the mug initially heats up, it loses heat through convection. This in turn causes it to extract more heat from the coffee through conduction. Ceramic has a higher specific heat (~900 J/kg.K) than glass (~800 J/kj.K), which means that ceramic loses heat through convection at a slightly slower rate than glass. A ceramic mug should lose heat by convection about 11.1 percent slower (100 – (800 J/kj.K / 900 J/kj.K)) than a glass mug of the same shape and size.

In short, unless you’re a scientist, a ceramic mug will keep your coffee slightly warmer than a glass mug.

Locally recycled glass is the most environmentally friendly

Deciding whether glass or ceramic has an ecological advantage is not as simple as comparing their heat losses. Both have advantages and disadvantages.

On the one hand, glass can be recycled, but ceramics cannot. (Technically, some ceramics can be “downcycled” and incorporated into other ceramic products, but downcycling results in a poor quality ceramic that isn’t typically used in mugs). This means that glass has a clear advantage over ceramic when comparing the environmental impact.

On the other hand, ceramic does not weigh as much as class and therefore requires less energy to ship. While the difference in weight between a glass mug and a ceramic mug might seem negligible, when shipping hundreds or thousands of mugs, even a fraction of an ounce adds up.

The best choice for the environment would be to buy a glass mug made from locally-sourced recycled glass. This takes advantage of recycling glass without the trade-off of using more fuel to transport it over long distances. If you can’t find a mug made from locally recycled glass, you’ll have to decide whether recycled glass or lighter-weight ceramic is better for the environment.

The next time you come across a mug you like, don’t just think about a mug’s aesthetics. Consider how the mug is affecting your coffee drinking and the environment. A cup says a lot about a person. Yours should reflect you well in all three areas: aesthetics, thermodynamics, and environmental sustainability.

We Italians often drive bartenders crazy with the strangest requests. But after the big diatribe between the supporters of “normal” coffee and those who can’t do without their decaffeinated one, there’s another one right away.

This is exactly what separates those who love their coffee in a cup and those who only drink their coffee by the glass. In this article we will discuss the differences between these two ways of tasting one of Italy’s excellences.

The history of coffee in a glass

Every type of coffee, from the classic espresso (Link) or cappuccino to the more unusual ones like the Marocchino coffee, has a story.

Coffee in a glass is no exception. Although this custom has spread throughout Italy in recent years, its origins seem to be rooted directly in the capital. Incidentally, in the south of Rome it has been popular for some time to order a glass of coffee at the bar.

Whether trend or real tradition, here we tell you everything you need to know about coffee in a glass.

Coffee in a glass: the reason for the choice

Nowadays, we hear (and say) more and more often “an espresso by the glass, please” at the bar. But what are the reasons why this is preferred to the classic coffee in a cup?

The glass and the elegance of the coffee

If you love coffee in all its different shades, you must choose to drink your coffee from a glass because looks matter too and coffee is no exception. The transparent aspect of this type of small glass brings out the elegance of the hazelnut color of an Italian espresso much better than porcelain coffee cups. This way the eyes can enjoy the sight of the coffee before the taste buds enjoy the taste! But there is a downside to this choice: the glass actually has poorer insulating properties, so your coffee doesn’t stay hot for as long.

The properties of the glass beaker.

According to those who love their coffee in a glass, the conical shape of the glass allows the coffee to form a higher and denser foam at the top, allowing the Italian espresso to retain all its organoleptic properties. The narrow rim of the special tall narrow glass also offers a comfortable and delicate feeling on the lips.

Why some prefer to drink their coffee in a cup

The cup is an object that we are used to seeing every day today. But few know its secrets: from the material, to the shape, to the temperature to which it should be heated.

The porcelain coffee cup

The coffee mug is made of porcelain, but do you know why? This material responds evenly to temperature changes, is resistant and neutral to contact with alkalis and acids and its heat insulating ability allows the coffee to cool down more slowly.

The shape of the cup

Every type of coffee has its matching cup. For espresso, it should be thicker to keep the coffee hotter for as long as possible, and the mouth of the cup should also be narrower to reduce surface tension and keep the froth longer. However, the bottom of the cup should be homogeneous and rounded to level the froth.

For the cappuccino you need a particularly thick cup that can retain the heat; we also recommend a cup that is slightly wider at the top so that you can lift the espresso better when pouring in the frothed milk. This way it is easier to create latte art designs which are now very popular everywhere.

And do you prefer your coffee in a traditional cup or in a glass? You should try both and find out which one is best for you.

There are few things in life more irritating than a glass coffee mug. Well, maybe people who wear Caucasian skates who think they’re somehow fooling everyone into thinking that instead of a foot, they have some kind of Ken doll nub with a razor-sharp blade popping out of it. Or maybe even those rare, emotionally privy men who, just before sipping a small, sensible sip of fair trade Argentinean mate on-the-go from an eco-conscious thermos, whisper confidently to a friend, “We you’re pregnant.” Or maybe even full-grown adults People who wear head-to-toe plush tracksuits and bring real, real pillows on two-hour bus flights from New York to Charlotte because the slightest prospect of not being comfortable will trigger an existential spiral they’ll never get out of will recover.

Yes, perhaps the jar isn’t the worst of the worst, but nonetheless its nature proves the existence of dark, cataclysmic forces bent on suppressing truth, beauty, and common sense in this world.

Because let’s face it, glass coffee cup lovers, who are you kidding? Are you so curious about your coffee that you absolutely have to keep an eye on it? Do you really need the Drinkware version of a 24/7 motion and sound sensitive baby monitor? Are the guessing games too much for you? Does seeing the exact coffee level ease the pain of having to choose between tangible, empirical knowledge and the utterly unfathomable idea of ​​belief that exists deep within the muddy sludge of your baboon DNA?

And if it isn’t, then what? What lies behind such an unbearable choice? During your studies abroad, did you ever have a delicious little cappuccino served from a tall glass mug in a cute little cafe by the Trevi Fountain while the bells rang and night fell over the Eternal City? Did you giggle wiping some sudsy cream from your nose as the Vespsas whizzed by and the Roman teenagers played grab-ace and suck-face as you wrote in your Moleskine hope journal about never coming back, that you were a citizen? the world now? And then, three months later, you returned to your childhood home in suburban Maryland in your summer scarf and culottes, and you yelled at your mom for not realizing how empowering it was to pay $200 to learn how to make gnocchi hand-rolling under the Tuscan starlight?

Is that it? Is your glass coffee mug the lifeline to the idea of ​​what could have been? Do you sometimes sit in your kitchen early in the morning and stare at her and think, “I have class. Just like this mug.” and then down a can of Monster Energy, hop in your Impreza and set off for a hard day’s work at the local dog food specialty company?

Or are you a little batcher? A solubility-conscious Chemex-4-lyfe-baller yelling at specialty coffee conventions about the ideal pH balance in a cold-brew mug? Are you a big dog in the Aeropress world? A shot caller? A big-dick chain swanga rocking to the sound of Peruvian ocarina tracks on Sunday mornings while you pound the ones and twos on a proper moka pot?

Despite all this, the fact remains that glass mugs retain heat by convection a little faster than ceramic mugs. That’s fact. Glass is also easier to source and recycle locally than ceramic. Fact. And one last fact:
