Drinking tea in moderation has a certain medical and health care effect on human body. Has effects in refreshing mind, relieving fatigue, promoting digestion, diminishing inflammation, sterilizing, preventing and treating intestinal infectious diseases, preventing heatstroke, quenching thirst, and promoting fluid production.
There are many kinds of tea products on the market. According to the classification and processing of commercial tea, there are seven kinds of tea sold in China: black tea, green tea, scented tea, oolong tea, pressed tea, Pu 'er tea and yellow tea. All these teas are made from fresh leaves, buds and shoots of tea trees. Different processing methods make different kinds of tea.
1, there are two kinds of black tea: one is strip tea, also known as Kung Fu black tea, including political Kung Fu and Tan Yang Kung Fu; One is broken black tea. It is divided into four processes: withering, rolling, fermentation and drying.
2. Green tea processing is divided into three processes: enzyme fixation, rolling and drying.
3. Yellow tea processing can be divided into four processes: enzyme fixation, rolling, yellowing and drying. The yellowing process is the key process to form the characteristics of yellow tea. If there is no process of turning yellow and blocking green, it cannot be called yellow tea.
4. Pu 'er tea is green tea after preliminary processing, mainly produced in Yunnan Province. Fermentation is the key to the processing of Pu 'er loose tea. After processing, the taste of Pu 'er tea is not bitter or astringent, and the caffeine content can be increased from 4% to about 5.5%.
Oolong tea is a semi-fermented tea, which is mainly produced in Wuyishan area of Fujian, followed by Minnan area of Fujian and Chaoshan area of Guangdong. The processing method of oolong tea is quite different from that of black tea and green tea, and it has the following requirements: (1) Tea should not be picked too early or too tender; (2) Oolong tea must be dried; (3) adopting the technology of combining "turning green" with "cooling green" to make the tea reach the semi-fermentation level; (4) The baking process of oolong tea is particular.
6. Scented tea is made of the best tea leaves and mixed with rich and fragrant flowers. It smells of flowers and tea.
7. Pressing tea is to steam loose tea, knead it and put it into a model for pressing. Regular and even shape, easy to transport. The soup is bright red and the leaves are brown and red.
In the face of numerous tea production enterprises and brands, as well as tea products with great differences in product quality, consumers should pay attention to the following points when purchasing tea:
First, correctly buy new tea and identify old tea. As the nutritional components of tea changed during storage, the sensory quality of tea became worse with the extension of storage time. Therefore, when shopping, buy the recently produced tea, that is, buy new tea and buy less old tea.
Second, correctly purchase spring tea and identify summer and autumn tea.
Spring tea is the best quality green tea in a year, because its buds are full, its color is green, its leaves are soft and its white hair is exposed. Compared with summer and autumn tea, spring tea has fresher taste, stronger aroma and more obvious health care function. In addition, there is generally no harm of pests and diseases during the growth period of spring tea, so there is no need to use pesticides, and tea pollution is less. The contents of amino acids and vitamins in summer tea are obviously reduced, which makes the contents of anthocyanins, caffeine and tea polyphenols in summer tea increase obviously, so the taste is bitter. Autumn tea has light taste, low aroma and yellow leaves. Therefore, when purchasing tea, we should carefully distinguish between spring tea and summer and autumn tea, and choose spring tea correctly.
Third, correctly distinguish famous tea from ordinary tea:
1, West Lake Longjing Tea is produced in Xihu District, Hangzhou, Zhejiang. Tea is flat, tender, neat in color, even in width, yellow-green, smooth to the touch, with one bud, one leaf or two leaves, the bud is longer than the leaf, generally less than 3 cm long, the bud leaves bloom evenly, without pedicels and fragments, and it is small and exquisite.

Golden and bright color, fresh aroma, light yellow tea color and sweet and refreshing taste. After brewing, it looks like buds are rushing to the water, standing upright, and then slowly sinking into the bottom of the cup, shaped like a group of unearthed bamboo shoots and like an upright silver needle. The fake silver needle smells like grass, and the silver needle will not stand up when it is soaked.
6. Qimen black tea is produced in Qimen County, Anhui Province. Tea leaves are brownish red in color, cut into 0.6 ~ 0.8 cm, with strong taste, strong alcohol and freshness. Fake tea generally contains artificial pigments, which are bitter and light in taste and irregular in leaf shape.

The leaves are as heavy as iron and as beautiful as Guanyin, mostly spiral, green in color and green in pedicel, with natural orchid fragrance. The soup is clear and golden in color, mellow and sweet in taste, slightly bitter at the entrance, and then turns sweet. When brewing, it spreads at the bottom of the leaves, with green and red edges, plump and bright, and every tea has tea branches. The fake tea leaves are slender and thick, with no green and red edges. After soaking for three times, the leaves have no fragrance.
Four, product packaging labels should be complete, some famous teas have regional protection signs, pollution-free tea and organic tea have national recognition signs on the packaging, choose varieties suitable for your own taste and buy products you need.
Five, choose the products of well-known enterprises with large scale and good product quality and service quality. Due to the strict quality control of raw materials, advanced production equipment, high management level and guaranteed product quality in large-scale production enterprises.
6. When consumers taste tea, (1) first look at the shape of the tea. Generally, high-grade strip tea has delicate raw materials, fine workmanship, tight rope, exposed seedlings and large quantity; Low-grade strip tea has coarse and old raw materials, extensive workmanship and loose rope. Generally, the color of high-grade tea is fresh and smooth, while the color of low-grade tea is dry, lacking luster or heavy and old-fashioned, with mixed colors; Old tea is insipid. High-grade tea should be stripped of tea leaves and non-tea inclusions, while low-grade tea is allowed to have some tea tip inclusions, but non-tea inclusions are never allowed. Smell the aroma, high-grade tea is fragrant, fresh and lasting; Mid-range tea smells high, but it doesn't last long; Low-grade tea has a low fragrance and is often heavily smoked. If there is a smell of smoke, rancidity, mildew, burnt smell, old fire, etc., it is inferior tea, and serious cases should be regarded as deteriorated tea. (2) Distinguish whether the taste of tea soup is pure, dense, turbid, strong, fresh, pure, bitter and irritating. The entrance of tea soup is slightly bitter, the aftertaste is sweet, and the bitter taste is the worst. Generally, broken black tea is rich in flavor, fresh and refreshing, and green tea with delicate raw materials is sweet and mellow. Kung fu black tea should be fresh, sweet, tender and refreshing, or fresh, strong and sweet. Oolong tea should be mellow and sweet. (3) Look at the color of the soup. Generally, the color of high-grade green tea soup is light green and bright, so is apricot green and bright, so is black tea red and bright, and golden round is golden and bright.
Tea is a kind of health food suitable for all ages, and all kinds of nutrients are easily absorbed and utilized by human body, so it is a good drink for most people.
Although tea is a good drink, consumers should also pay attention to the following points when drinking:
1, drinking overnight tea has advantages and disadvantages. Overnight tea is not suitable for drinking because most vitamins have been lost for a long time, and protein and sugar in the soup have become nutrients for bacteria and mold reproduction. However, the overnight tea that has not deteriorated has its own magical use in medical treatment. Rich in acid, it can prevent capillary bleeding, such as stomatitis, tongue pain, eczema, gingival bleeding, sores and abscesses, and can be treated with overnight tea. Eyes often shed tears or have bloodshot eyes, and you can also wash your eyes with overnight tea several times a day, with good results. Before and after brushing your teeth in the morning or after meals, you can rinse your mouth with a few mouthfuls of overnight tea, which can make your breath fresh and have the effect of fixing your teeth.
