What is coffee extraction?
Let's start with a question: what on earth is a cup of coffee? Simply put, when the water passes through the coffee powder, it dissolves and brings out some of the soluble matter in the coffee powder, and then we get a cup of coffee. In other words, in this cup of coffee, in addition to water, it is taken out of the coffee powder by water.
The other question is, what affects the taste of coffee in a cup of coffee? If you agree with me above, then the answer to this question is that the substances brought out of the coffee powder by water determine the taste of a cup of coffee.
From this, we can also explain today's concept that the process in which water releases soluble substances from coffee powder is called coffee extraction.
About 30% of the substance in coffee powder can be extracted, which intuitively means that in 100g coffee powder, we can extract about 30g. However, not all 30% of coffee is what we need.
Suppose that the substances we extract do not meet a standard, and we cannot fully release the taste of coffee. If we extract more substances than that standard, we will release too many substances. The consequences of these over-extracted substances on the taste of coffee will be disastrous, such as: the taste of coffee will become messy and bitter.
Therefore, a good cup of coffee is to grasp an appropriate amount of extraction, extract that part of the substance we need and not too much or too little extract some substances we do not want, so as to ensure a balanced and delicious taste of the coffee.
The concept of coffee extraction is very important and is the soul of coffee making.
