Tell you why the hand-brewed coffee is so weak. What is the reason for the weak taste of hand-brewed coffee?

Here, the feeling of "light" coffee taste is mainly reflected in the difference between bitter taste and liquid roundness. The bitter taste of coffee is easier to understand. The term "body" is used in the professional evaluation of the roundness of the liquid, which refers to the difference in the pressure of the coffee liquid on the inner wall of the oral cavity. A more intuitive understanding is the difference in feeling when we drink water, milk and syrup. This difference is mainly caused by the different contents of water, oil, lactose and other components in the liquid.

To illustrate the problem, start with the difference between the coffee beans used in the cafe and the hand-made coffee beans you buy.

Most of the coffee beans used in the cafe are blended beans, that is, robusta beans from different producing areas are mixed with Arabica beans according to a certain proportion. Robusta is used to make instant coffee, canned coffee, liquid coffee and other industrial production of coffee beans, low price, characterized by bitter taste, ordinary flavor, but rich in oil.

Arabica is recognized as a kind of high-quality coffee beans. with the rise of the third boutique coffee wave that emphasizes the unique flavor of different producing areas, Arabica single beans are more and more sought after by senior coffee lovers because they can show delicate coffee flavor. hand extraction has become the best way to taste Arabica beans. Although the oil is not as rich as Robbosa beans, it is better than Robbosa beans in aroma, flavor and sour balance, and the price is much higher.

Blending coffee beans of different producing areas and varieties in different proportions can not only obtain more stable quality but also better control the cost.

So the difference in oil content of different coffee beans is one of the reasons why you feel that hand-brewed coffee is not as rich as Italian coffee.

Hand-made coffee beans are also available on the market, but you may still think this kind of coffee is "lighter" than the one you bought.

It also starts from the degree of roasting of coffee beans. In general, the more roasted coffee beans are, the more bitter they taste and the more fully the oil is released. Most coffee shops use Italian-roasted coffee beans, while coffee beans that emphasize high-quality hand-made coffee are generally roasted moderately or lightly, so the Italian coffee beans in the cafe are more bitter and greasy than those roasted by hand in Arabica.

Next, you have to pick up the differences in the way of extraction. I believe that when you walk into the cafe, the first thing that catches your eye is a variety of eye-catching Italian coffee machines.

The working principle of these coffee machines is that the espresso liquid containing oil is extracted instantly by high temperature and pressure. One serving of Espresso is only about 30ml, while hand-brewed coffee needs to add pure hot water with different 200--350ml. The significant difference in water content between the two different extraction methods is also an important reason for the difference in taste.

In addition, hand pulping usually needs to be filtered with flannel or filter paper, which inevitably takes away some of the oil in the coffee while filtering the coffee grounds.

You must think it tastes bad to make coffee by hand when you see it here. But the result is just the opposite. what about the rich taste experience of flowers, fruit, caramel, chocolate and so on in their own hand-brewed coffee?

This is because when the concentration of the liquid is very high, our taste buds become slow to the subtle taste sensation, just like the espresso Espresso extracted by machines. If it were not for supporting the swollen eyelids caused by all-night overtime (actually all-night TV shows or games), I am afraid few people would be willing to drink it directly. And a cup of powdered water can really bring a colorful taste experience than just the right hand-made boutique coffee.
