Update:04 Dec 2020

  There are many types of China green tea. The bulk of China green tea includes stir-fried green tea, roasted green tea, steamed green tea, and dried green tea. According to the shape of the famous China green tea, there are flat-shaped China green tea, single-bud-shaped China green tea, and straight-shaped China green tea. , Curved strip-shaped China green tea, curved spiral-shaped China green tea, bead-shaped China green tea, orchid-shaped China green tea, and tie-shaped China green tea. Different appearances of China green tea in various poses are its important characteristics. Therefore, the quality evaluation points of China green tea first focus on appearance.

  The shape of the long stir-fried green requires a tight, even, sharp, green color. The green China green tea is still tight and straight, with sharp, sharp, dark green color. The shape of bead tea is required to be round like beads, heavy and even, and green in color. The steamed green sencha has a straight shape and a dark green color.

  The color of the famous China green tea generally requires emerald green, but the common drawback is the color is dark or dark, which is mainly due to insufficient finishing, excessive twisting, or long accumulation time of the product.

  In addition to the quality of China green tea, the internal quality is also very important. The internal quality of China green tea generally requires high and long-lasting aroma. The soup is bright yellow and green, and the taste is strong but not astringent, fresh but not light.

  The common disadvantages of China green tea aroma are the smell of smoke, which is caused by burnt leaves caused by excessively high curing temperature, or the smell of smoke caused by leakage of smoke from the curing machine and dryer. The second is the peculiar smell of ink and plastic, which is polluted by the peculiar smell of packaging material printing ink or packaging plastic. The third is the smell of water and stuffiness, which is caused by the accumulation of tea for too long in the preparation or the baking temperature is too low.

  Generally, China green tea is rich in amino acids and vitamin C. The higher the amino acid content, the better the quality of China green tea. This has been confirmed. The content of vitamin C can be regarded as the quality of China green tea. Indirect pointer. The quality of China green tea is that it is fresh and natural and faithful to the original taste. The tea soup must be sweet and refreshing, and at the same time it has a light green grass or cooked chestnut fragrance.

It is fresh, refreshing and sweet, and most of the ingredients retain the original appearance and are not oxidized. Therefore, China green tea presents the typical characteristics of "green soup, green leaves, fresh and natural".

  For China green tea, the identification of dry tea is particularly effective. For example, Longjing, it is slippery to the touch, grab a handful and sprinkle it down, the good tea party will not spread out in piles. The best color is not emerald green, but slightly yellow. If people want the price of Shifeng Longjing, and the tea is green, then you at least know that this is a fake Shifeng. If China green tea is not well hidden, the color of dried tea will change. These are very obvious. Any tea will be faked. Some dry tea looks good, but it tastes disappointing. But understanding the characteristics of dry tea can at least reduce the chance of being fooled.

  The quality of tea can be evaluated in the four aspects of color, aroma and shape when there is no scientific instrument and method for identification. These four aspects are used to assess the quality of tea, usually by seeing, smelling, touching, and tasting. Look at the shape, color, smell, touch the body, and open the soup.

  Color-different teas have different color characteristics. Fried green in China green tea should be yellow-green, roasted green should be dark green, steamed green should be emerald green, and Longjing should be slightly beige in bright green; if China green tea is dark and dark brown, the quality must be different good. The vapor color of China green tea should be light green or yellow-green, clear and bright; if it is dark yellow or cloudy, it is not a good tea. Black tea should be dark and oily, the soup color is red and bright, some top-grade black tea, the tea soup can form a yellow oil ring around the cup, commonly known as "golden circle"; if the soup color time is dim and cloudy, it must be inferior black tea . Oolong tea is better with a greenish brown color.

  Aroma ---- All kinds of tea have their fragrance, such as China green tea with delicate fragrance, top-grade China green tea with orchid fragrance, chestnut fragrance, etc., black tea with fragrance and sweet or floral fragrance; Oolong tea with ripe peach fragrance, etc. If the aroma is low, it is regarded as inferior tea; the tea with stale smell is stale; the tea with moldy smell is spoiled. Even Kuding tea has a natural aroma. Scented tea attracts tea customers with its strong fragrance.

  Taste-or the taste of tea, the taste of tea itself is composed of bitter, astringent, sweet, fresh, acid and other ingredients. The proper proportion of the ingredients makes the taste mellow and delicious. At the same time, different teas have different tastes. The first-class China green tea has its bitterness at first taste, but the aftertaste is strong, which makes the mouth and tongue healthy; crude and inferior tea is light and tasteless. , And even astringent mouth and tongue. The high-grade black tea has a strong, strong and fresh taste; the low-grade black tea is flat and tasteless. Kuding tea is very bitter in the mouth, but it tastes sweet after drinking.

  Appearance----The quality of tea can be judged on the appearance of the tea, because the quality of the tea is directly related to the fresh leaves of the tea picking, and it is also related to the production of tea. This is reflected on the appearance of the tea. For example, a good Longjing tea is light, flat and straight, and looks like a bowl nail; a good pearl tea has round and tight particles; a good time black tea strips are tight, and the black tea particles are neat and uniform; a good Maofeng tea bud Haduo, bud front and so on.
