What is the thickness of Body and alcohol in coffee? how to make better Body in roasting or brewing?

What is Body?

Let's start with the basics: Body is the texture of coffee. In the Professional Barista Handbook, Scott Rao defines it as "the weight or fullness of a drink in the mouth".

Although Body is an element of taste, it is worth noting that there may be differences. In the coffee dictionary, Maxwell Collonna-Dashwood wrote: "it's interesting to consider that you might encounter a light body with sticky taste or a large fuselage with juicy taste."

Body is not something we taste, but a feeling we feel. However, it will affect the overall flavor of coffee. This is because flavor is a combination of many factors-taste, aroma, texture, sound and even visual effects.

In my experience as a barista, Body is one of the three things coffee drinkers have been looking for (as well as bright acidity and clear flavor).

Body insoluble science

If we want to emphasize Body, we need to know how it is produced. That means talking about extraction. This is the process of extracting flavor and aroma compounds from dry coffee to water and becoming our favorite brewing coffee.

In the process of extraction, substances can be divided into soluble substances and insoluble substances. A soluble substance is a substance that can be diluted in water. On the other hand, insoluble substances are solids and oils, which remain suspended in liquids rather than dissolve. They are like protein molecules and some coffee fibers. These insoluble substances-especially oil-increase Body.

Why are some coffees fuller than others?

There are many factors that determine why one particular type of coffee has more Body than another. Some coffee varieties prefer ​​ to Body. The same is true for specific coffee processing methods, brewing methods and filters. And you can control the baked profile to produce more Body.

Now let's take a look at some of these factors, from raw beans to the final drink.

If your Body is strong, there are three options: accept its low level of Body; try to highlight Body; by processing, baking, brewing or mixing it with coffee to make Body healthier.

Washed coffee has a finer taste: it is clearer and cleaner than it tastes. As for nature, you can expect a bigger, more round Body.

The natural ingredients of honey and pulp are also related to Body. Generally speaking, the more mucus left on the cherry, the more Body you will get in the cup. Black Honey Coffee stands out for its syrup sweetness.

How to embody Body through baking

You can roast raw coffee to emphasize the size or dilute it, depending on what you think of specific coffee beans.

First of all, let's clarify one thing: deeper baking is usually associated with more Body. But, as Barista Hustle's Matt Perger points out, the color of beans and the development of baking are not always linked. Baking is a complex combination of many factors, and a good roaster will control the heat throughout the baking process to enhance its desired profile.

In particular, Sweet Maria's, a green coffee supplier, emphasized its ability to manipulate Body by controlling the duration of the first rupture. If you do it right, the first tensile crack will increase Body. "the taste of syrup is related to the feeling of specific carbohydrates, and carbohydrates will be released more as the first crack extends," they said on their blog. "

In addition, Rob Hoos explains in the Flavor characteristics of Coffee that if the roaster also extends the Maillard reaction, it may lead to more melanin production. This, in turn, means more Body.

Keep in mind, however, that if you overbake, the baking speed may stop and then bake. This will produce a flat dough drink. You need to weigh all the different reactions that take place inside the coffee beans to create the best roasting effect for each type of coffee.

How to make a good body

Because the oil forms the wine body, the amount of oil allowed into the final glass by the cooking method and filter can have a huge impact on the wine body. There are many differences between these cooking methods.

Manual brewing methods are often described as sitting scales with high body and low definition at one end and high definition and low body at the other end. For example, the French media is famous for its image. On the other hand, dumping is usually related to clarity. AeroPress is known for its flexibility: you can brew according to your mood to enhance Body or clarity.

One of the reasons why the French kettle is famous for its body is its metal filter. Paper traps a lot of oil in coffee, while metal allows them to pass through. Compared with the French kettle, Chemex is famous for its cleanliness in brewing, thanks to its thick paper filter. If you can choose either a metal filter or a paper filter, your taste will be more flexible in the final brewing.
