I. Overview of Green Tea:
Green tea is one of the main tea types in China. Green tea is made by taking the new leaves or buds of the tea plant, unleavened, and made by processing, shaping, drying and other processes. It retains the natural substances of fresh leaves and contains nutrients such as tea polyphenols, catechins, caffeine, amino acids, and vitamins. Green tea is characterized by the rapid elimination of enzymes at high temperatures after fresh leaves are picked, which inhibits the oxidation of tea polyphenols. Therefore, green tea has the characteristics of "three greens": dry tea green, tea soup green, the bottom of the leaf after brewing is also green, and green tea is also named after this.

Sixth, green tea brewing, storage:
【Tea Brewing Three Throwing Method】
1, the order of tea throwing is exquisite
Do you make tea by putting tea leaves first or pouring water first? Or pour half the water and put the tea leaves? Don't underestimate these problems, take green tea as an example, different green teas have different tea throwing methods.
2, the upper projection method: first pour water, and then put tea, let the tea slowly sink.
The upper throwing method is suitable for heavy bones and multi-bud tea leaves, such as famous green teas such as Biluochun and Xinyang Maojian. Due to the weight of the body, the tea leaves will slowly sink on their own after being put into the water, gradually releasing the contents, and the tea attached to the surface is also slowly dispersed in the water, so that the brewed tea soup tastes fresh and will not appear turbid because of too much tea.
3, the middle throwing method: first pour water, about one-third of the container is filled, and then put the tea, wait for the tea to soak for a while, and then inject water. The zhongtou method is generally suitable for green tea such as Longjing. First, pour boiling water into about 1/3 of the cup, when the water is cool to about 80 ° C, put the tea leaves in the cup, and then pour about 80 ° C boiling water from a place along the bowl. When filling water, pay attention to the height of the water column, and you can also control the water temperature. With this brewing method, there is no need to worry about the astringency of fresh and tender green tea due to excessive water temperature.
4, the next throwing method: first put the tea, and then pour water.
Green tea such as Taiping Monkey Kui and Liu An Gua Slice is suitable for brewing with the lower casting method, their leaves are not particularly tender and large, if you want to taste more full, it is best to put the tea first and then pour water.
【Water temperature for green tea】
Many tea friends are accustomed to brewing some fermented tea methods when brewing green tea, directly using boiling water to brew green tea, but the water temperature is a factor that has a great impact on the quality and taste of green tea. Because green tea is made of new leaves and young buds, excessively hot water will cause the tea leaves to be brewed, and the ingredients inside will be sexually altered and lost, which will affect the nutritional value and taste of the tea soup, so the general green tea water temperature is preferably 80 ° C, so that the nutrients of the tea can be perfectly retained.
【Tea set for making green tea】
In fact, when we drink tea, the tea set is also very exquisite, only by using a good tea set, can the charm of the tea itself be released to the greatest extent. Then when we brew green tea, we can use glassware, which can better show us the original taste of the tea soup.
【Green Tea Storage】
As the temperature rises, tea storage becomes difficult. After opening, the tea leaves are easily spoiled and spoiled, so this time the tea pot highlights its role. There are many kinds of tea pots, such as wood, ceramic, stainless steel, and purple sand. Purple sand tea cans have always been called "tea storage artifacts" by industry insiders. Indeed, compared with other materials, purple sand tea cans have better breathability, which is conducive to the later transformation of tea leaves, especially suitable for storing green tea, Pu'er tea, white tea, black tea and so on.
