How does coffee rookie taste the flavor of hand-brewed coffee? Is the tea in boutique coffee astringent?

"isn't tea sweet?! "" the feeling of tea is astringent. "" isn't the taste of tea? "the article is inspired by life, and the above conversation is a topic that Qianjie baristas recently heard three friends whispering about for a while.

Before you understand the sense of tea

First, let's learn about the astringency.

Astringency belongs to oral touch. The appearance of "astringency" is that polyphenols in food show themselves in the mouth, giving the mouth a sense of roughness. A strong sense of roughness can be a sense of dryness, will stay in the mouth for a long time, and will affect your experience when you taste the next food. Astringency is annoying, but we still need to divide astringency into two groups: negative astringency and positive astringency.

Negative astringency is irreversible. For example, the coffee variety itself has too much chlorogenic acid, which will be degraded into quinic acid during baking. Quinic acid is a phenolic acid and non-volatile, so it can not be smelled through the sense of smell, but it tastes bitter and has a strong sense of astringency. For example, coffee beans are not completely dehydrated in the roasting process, and the moisture in raw beans will affect the heat transfer, so it is easy to appear that the beans are ripe, but the bean core is still unripe, so it tastes like herbs and has a green and stinging feeling. '

The positive astringency is the layering that enriches the coffee. For example, the slightly astringent taste of citrus peel, clean acidity and slightly astringent skin can remind us of eating endocarp (the layer of flesh) when eating grapefruit pulp, which is slightly bitter in sour and sweet, not objectionable and sweet.

What kind of experience is the feeling of tea?

First of all, we drink tea has an obvious bitter taste, in many cases is the quality of the tea itself / excessive extraction during brewing to release too much tea polyphenols resulting in bitter taste. With high-quality tea and proper cooking, the tea will be filled with the unique aroma and sweet taste of the tea variety after passing through the mouth.

For example, when we taste green tea, green tea itself retains a lot of tea polyphenols, all the mouth will have a rough (slightly astringent), fresh aroma. At the same time, you will also feel the fishy smell of seaweed food, which is called the taste of purpose (fresh taste, a special taste brought by amino acids).

For example, when tasting green tea (Oolong, Tieguanyin, etc.), because it belongs to semi-fermented tea, the tea is smooth, mellow, refreshing, sweet and persistent.

For example, when tasting black tea, because it belongs to fully fermented tea, the tea feels full and solid, the aroma is rich, and the taste of tea is mellow and sweet.

OK, let's go back to the flavor of coffee ~ in fact, the sense of tea we drink in coffee is not comparable to that of drinking tea directly. The sense of tea in coffee is often reflected in the aftertaste of coffee and the degree of sweetness in the mouth. It reminds you of a certain aroma / taste / degree of sweetness of tea or tea.

In front of the street, when tasting the washed Yejiaxuefei coffee, you will often feel that the aftertaste of the coffee has the unique flavor of green tea or the fresh aroma of green tea itself.

In tasting the green label coffee of the Jade Manor treated with water, you will feel an obvious feeling of sweetness and lightness, just like drinking Tieguanyin tea, the aroma and aroma are very long-lasting.

When tasting the sun-treated Yunnan Iron pickup Coffee, you will feel that Yuyun has a solid sense of sweetness, like drinking black tea.

The last gossip.

In the world of coffee, the flavor is ever-changing, and everyone's senses are different, and not everyone can feel the sense of tea in the coffee flavor. In foreign countries, there are few descriptions of tea in the description of the flavor of high-quality coffee beans. However, in China, we like to use tea / tea flavor as a flavor description.

On the one hand, Chinese people are "born" familiar with the sense of tea, on the one hand, they hope to let more people slowly change the inherent impression that coffee is only bitter, and let everyone know through the description of tea / tea flavor that fine coffee can be the same as good tea. It has high-quality aroma, clean taste and sweet taste.
