Green tea is the well -deserved king of my country's six major tea categories. Whether it is the number of tea or the size of the origin, it is the highest in the country. Those who love tea may not drink white tea and black tea, but it is unlikely that they have not touched green tea. In the four major tea production areas, most of them have their own masterpieces of green tea, such as Longjing and Biluochun in the West Lake in the Jiangnan Tea Area, and Liu'an Gua Melon in the Jiangbei Tea Area, are all the top ten famous tea in the country.

Green tea has been killed to remove the odor in fresh leaf raw materials, and then twist and bars. It does not need to be fermented. Among the six major tea, the only green tea production technology is the most concise, and it is a typical non -fermented tea.

The advantage of non -fermentation is that the original essence of the tea can be retained. Camera polyphenols, catechins, chlorophylls, caffeine, amino acids, vitamins and other nutrient content have high nutritional content, tender yellow green green, clear soup, fragrant aroma, fresh entrance, the entrance is refreshing, the entrance is refreshing, the entrance is refreshing, the entrance is refreshing, and the entrance is refreshing. Back to be smooth, most people can accept it.

The four categories of green tea.

Green tea is located in the north and south of the motherland, with hundreds of thousands of varieties, and different production methods. Generally speaking, it can be divided into four categories:

Fried green: This is the most important skill in the process of green tea processing. According to the different operation methods and strength of manual and mechanical operations during the drying process, it can be divided into long -fried green, round fried green, flat fried green, etc. West Lake Longjing is a flat -fried green tea in green green tea.

Baked green: After killing the green, the drying method of drying charcoal is a process. The aroma is generally not as fried, but the quality of the special -grade blue -famous tea is excellent. Among them, Huangshan Maofeng, Taiping Monkey Kui, Liu'an Gua Milk, etc. are all outstanding masterpieces.

Danqing: As the name suggests, use sunlight to dry. This processing technology is mainly concentrated in the two lakes and Guangdong, Yunnan -Guizhou and other places. In particular, green green tea with large leaf species in Yunnan is the most special.

Steamed green: The oldest green tea production technology has appeared in the Tang Dynasty, and it has been passed to Japan and has been retained to this day. Domestic steamed green tea is the most famous with Enshi Yulu in Enshi, Hubei.

The shelf life of green tea.

Green tea has not been fermented, and it will not continue to be transformed after the production is completed. The maximum essence of fresh leaves is retained, especially tea polyphenols, caffeine and amino acids. Among them, the ingredients of tea polyphenols and caffeine retain more than 85%, and chlorophyll content is at least 50%.

Therefore, drinking green tea often can refresh the brain and keep people more energetic energy, especially after lunch afternoon work hours, a glass of green tea makes you full of vitality. More importantly, green tea has strong antioxidant resistance. Young people who often play mobile phones can drink more.

The production cycle of green tea is very long. It can be made in the three seasons of spring, summer and autumn, but the most spring tea is the most. Autumn tea is second, and summer tea is the worst. Green tea pays attention to freshness. It is best to drink it that year. After the New Year, it is Chencha, and the aroma will be much worse.

Generally speaking, the shelf life of green tea is about 18 months, and some tea merchants set themselves for 24 months. However, as far as I personally, the shelf life of green tea is best within one year. Because green tea has not been fermented, no matter how it is stored, it will be exposed to the air and slow oxidation, resulting in yellow and black.

If it is not stored properly, under high temperature, humid, and odor environment, green tea will change color and mold in just a few days, and it is not advisable to continue drinking. Therefore, when the green tea is stored, we must pay attention to the storage conditions.

For family storage green tea, first of all, a good seal must be sealed. Sealing is a prerequisite for all storage. Without sealing, tea will be quickly oxidized. Secondly, green tea should be stored at low temperature and placed in the refrigerator. Especially during the summer high temperature period, color will change color within 7 days in normal temperature environment. Again, moisture -proof and anti -light is critical. Water, humidity and light will also promote the deterioration of green tea oxidation.

In addition, it is necessary to remind everyone that the shelf life of green tea is only its best drinking period, not its last drinking period. If the tea is well preserved, you can continue to drink for two or three years of green tea. If it is not stored properly, the green tea of ​​two or three months is placed in room temperature, which will also change color and deterioration.

All in all, green tea must be kept at low temperature and density. If you are pursuing fresh and fresh, the new tea is the best choice that year. After a few years of green tea, if you are reluctant to throw it away and save well, there is no problem drinking yourself. Do n’t worry too much.
