How to distinguish between green tea and black tea, black tea and green tea

1. Green tea: This is the most produced type of tea in China, and its variety ranks first in the world. Green tea has the characteristics of high aroma, mellow taste, beautiful shape, and brewing resistance.

The production process is all through the process of finishing, kneading and drying. Due to the different drying methods during processing, green tea can be divided into roasted green tea, roasted green tea, steamed green tea and sun-dried green tea. Green tea is the most produced type of tea in China, and 18 tea-producing provinces (regions) in the country produce green tea.

China's green tea varieties rank first in the world, with tens of thousands of tons exported every year, accounting for about 70% of the world's tea market. China's traditional green tea, Mei tea and pearl tea, are popular with consumers at home and abroad for their high fragrance, mellow taste, beautiful shape and brewing resistance. 2. Black tea:

The difference between black tea and green tea lies in the different processing methods. Black tea is processed without killing, and withering, so that the fresh leaves lose a part of the water, and then kneaded (kneaded into strips or cut into granules), and then fermented, so that the tea polyphenols contained in it oxidize and turn into red compounds. This compound is partly soluble in water and partly insoluble in water, and accumulates in the leaves, thus forming red soup and red leaves.

There are three main categories of black tea: small black tea, gongfu black tea and black broken tea.

The finished tea is made by picking the young leaves of the tea tree that have been bathed in the morning glow, and there are different types and names because of the different manufacturing methods. The most important key to the preparation method is "fermentation", as a result of fermentation, the tea will gradually turn red from the original turquoise, and the more fermentation, the redder the color; Depending on the amount of fermentation, the aroma will change from leafy to floral, ripe fruit or maltose. Fully fermented tea is called black tea, and the brewed tea soup is vermilion and has the aroma of maltose; And semi-fermented tea, that is, oolong tea.

Oolong tea can be divided into three categories: light fermentation, medium fermentation and heavy fermentation, light fermentation such as Bao Chong tea (clear tea), which is characterized by high fragrance, elegance and golden soup color; Medium fermentation such as Tieguanyin, Narcissus, Frozen Top, etc., the soup color is brown, and the drink is old and heavy, and the "throat rhyme" is more emphasized; The heavy fermentation is like Baihao oolong, the soup color is orange-red, with a ripe fruit aroma. Unfermented tea is called green tea, and the brewed tea soup is turquoise or green with yellow in it, with the aroma of fresh vegetables, such as Longjing, Biluochun, etc.

The color of green tea dry tea is emerald green, the soup color is turquoise, and it is not fermented; Black tea is fermented, oxidized and has black tea pigments, which melt in water.

Needless to say, green tea. The characteristic of black tea is the red leaf red soup, which is the quality characteristic formed after fermentation, the color of the dried leaves is dark, the taste is mellow and sweet, and the soup color is red and bright. There are three kinds of black tea: "Gongfu Black Tea", "Red Broken Tea", and "Small Seed Black Tea", and the famous black teas are "Qi Hong", "Ning Hong", "Yunnan Red" and so on.
