There is nothing better than a cup of delicious coffee. when you pick up a coffee cup or glass to drink, you will first smell the aroma of coffee, followed by a satisfying taste, a lingering finish in the mouth.

If you choose a mug or glass, different shape, size, thickness, and material will affect how you feel about tasting coffee. It may add points to the aroma and flavor, or deduct points.

Is the co-founder and marketing director of KRUVE, a company dedicated to the development of coffee sieves to ensure the most accurate coffee powder thickness. They recently unveiled a new product, KRUVE EQ, which combines two kinds of glass to form a double-layer cup to ensure that the aroma and flavor of coffee are preserved. In order to produce this glassware, Mark and the R & D team studied the relationship between coffee flavor and drinking cups, and this article will suggest how to choose coffee cups.

Why do you have to choose a special cup for coffee?

The general mug is designed for only one purpose, so that people can safely hold hot drinks, so that we can avoid being scalded when tasting hot drinks, but this design has no effect on the flavor addition when tasting.

In fact, many people study whether there is an ideal container shape, size, and material for drinking coffee, but most people don't have so many choices when buying cups, let alone looking for cups of a certain shape, size, and material.

"sometimes we see shopkeepers, baristas or coffee fans drinking coffee from glasses that are not designed to drink coffee (such as wine glasses, whisky glasses), or people who use glasses to drink coffee, and these cups do not enhance the overall sensory experience," Mark said.

Science behind the ideal coffee cup

The study found that the material, size, shape and even color of the drinking container will have different effects on the flavor of the drink.

For example, a 2017 study found a correlation between cup shape and taste, finding that subjects tended to associate narrower cups with stronger aromas, shorter cups with bitterness and intensity, and wider cups with sweeter taste.

Another 2016 study pointed out that they studied bitter drinks (coffee) and sweet drinks (hot cocoa). When subjects drank coffee from cups with 3D printed patterns on the surface, the bitterness increased by 27%. When the subjects drank hot cocoa from a cup with a circular pattern on the surface, it was 18% sweeter.

In addition, according to Fabiana Carvalho's research, pink and round cups are closely related to sweetness, while tulip-shaped cups increase aroma, and so on.

What can a good cup add to coffee?

So we now know the importance of the cup to the experience, but what role does the cup play when it comes to drinking coffee? What is the impact of these designs on coffee? What other types of cups are suitable for us?

When choosing a cup, there are many factors to consider:

The relationship between cup shape and aroma: the design of top space and tilt angle.

The relationship between cup shape and flavor: the surface area and heat preservation effect of liquid contact mouth.

The relationship between cup size and aroma: the diffusion of aromatic molecules in the cup mouth space.

The relationship between cup material and temperature: coffee temperature stability, comfort and durability.

Let's take a closer look at them one by one.

Shape and size of cup

The space at the top of the cup is an often overlooked evaluation item in ordinary coffee shops, and many coffee fans like the aroma of coffee, which will be affected in turn.

"the top space will affect the amount of liquid drunk, which is an important factor in creating space for aroma, while tasting is actually a combination of taste and smell, in which the top space will also affect the olfactory experience. "

Research points out that smell is the main source of taste perception. When the container is narrower / smaller, the same amount of liquid touches the mouth less than the cup with a wide mouth, which reduces the sensory experience of the coffee aroma.

The top space is also affected by the tilt angle, which will affect your tasting experience when the cup is tilted to your lips. The more inclined the angle, the closer the coffee will be to the nose. If there is not too much space at the top of the cup, or if the cup is too small and too narrow, there will not be much room for you to feel the aroma of coffee through the tilt angle.

However, this does not mean that the narrow cup is not suitable for drinking coffee. In fact, it depends on the nature of the coffee you drink. Maybe narrow mouth is the cup suitable for drinking this coffee.

If there is enough space at the top, the narrow cup actually helps to concentrate the aroma of coffee. Use a spherical cup to concentrate and amplify the aroma, or a flute-shaped cup to concentrate the "flavor". In other words, wider cups concentrate aromas and narrower cups make the aroma feel stronger.

In addition, the width of the cup affects not only the aroma, but also different liquid surface areas. The liquid surface area represents the extent to which the coffee is in direct contact with the air. According to Mark, this affects the rate of oxidation, indirectly softening the tannins of coffee, and the rate at which calories are lost.

The larger the surface area of the liquid, in addition to increasing the contact area between the coffee and the air, it will also increase the sweetness and alcohol thickness. due to the accelerated oxidation rate of coffee, this kind of cup is more suitable for drinking coffee, such as Brazil and Sumatra. or medium-deep roasted coffee.

On the other hand, a smaller liquid surface area and a longer shape will slow down the oxidation rate, thus retaining the acidity of the fruit. This kind of cup is usually more suitable for drinking African coffee or medium-and light-roasted coffee. Another key to the shape of the cup is the design of the mouth, which affects the touch of the lips. Although the touch of the lips is rarely mentioned in the oral sensation, it does have a significant impact on the drinker's experience.

Material

Finally, the size of the cup is also important. The more coffee the cup can hold, the slower the cooling rate will be.

Ceramic, wood, paper, metal, plastic, glass, no matter what material the coffee cup is made of, will directly affect the heat preservation effect, temperature stability and durability of the coffee cup.

Ben Put, a well-known barista, says the cooling rate is often overblown and few glass makers know that you pour hot drinks into the glass.

However, when coffee is cooled, it can taste different flavors, which is an important consideration, and the material will directly affect the cooling rate of coffee.

American cup testing champion Ken Selby agrees and stresses the importance of balancing customer experience with coffee temperature, and there are still many stores that can't use the cup correctly. This cup may look attractive, but will it make the drinker hot? Is the material of the cup not thick enough? This will cause the drinker to be unable to concentrate on where he deserves to enjoy, because he will wonder when it will not be too hot.

Mark agrees, citing KRUVE EQ as an example: "We chose silica glass to make this product because of its super heat resistance, and then we decided to use double glass at the bottom of the glass, so that it has thermal insulation to make people comfortable and maintain the temperature of the beverage stable. "

But one of the common complaints about this double glass is that it stays hot for too long, so we design the top of the cup as a single layer so that the coffee cools faster without making the cup hot.

In other words, it's not as simple as a cup made of some material, but how you shape the material to make it into a cup to increase the drinker's experience.

So what does this mean to you as a reader? Whether you are a coffee drinker, a barista or a coffee shop owner, you can have more control over the flavor of the coffee without having to rely on luck like a lottery.

You can experiment on the extracted coffee by adjusting the grinding thickness, brewing time, etc., in order to give play to the best flavor of the coffee. Buy coffee with your favorite flavor, such as the sun in East Africa or fruity coffee in Central America. But you can also choose a cup to compare the same coffee, so that you can taste the coffee in a variety of ways.

If you want to buy coffee, you can skip a cup with a thick wall, or a cup with a small tilt angle, or this shape does not magnify the flavor characteristics of your favorite coffee. Instead, you can choose that the cup is designed to amplify the flavor characteristics of your preferred coffee.

To sum up, choosing a coffee cup is not like choosing the cup that best suits a certain type of coffee, but choosing a cup that can concentrate or magnify some of your favorite flavor characteristics.
