Green tea, with many famous products and high yield, is a kind of tea that consumers like to see and hear. So, how to preserve green tea? Below I will teach you some precautions for the preservation of green tea.

Green tea brewing method

1. Selection of tea set

Glass with good transparency is the first choice for brewing green tea, especially the delicate and precious green tea such as West Lake Longjing and Biluochun. Besides glass, white porcelain teacups are also a good choice. Porcelain tea sets are more elegant in shape, delicate in touch and easier to keep warm than glasses.

2. Water temperature control

The optimum water temperature for brewing green tea is about 85℃, which can be adjusted according to the brewing method, tea variety, season and freshness. Too high water temperature is not conducive to timely heat dissipation, tea soup will be stuffy yellow, bitter, with the smell of cooking soup. After brewing twice, the water temperature can be raised appropriately.

3. Brewing method

There are two common brewing methods of green tea, namely, upper throwing method and middle throwing method. The upward throwing method is to add enough hot water to the teacup at one time, and then add tea leaves when the water temperature is moderate. This method needs to master the water temperature very accurately. The more tender the tea leaves are, the lower the requirements for water temperature are. You can put some tea when the water temperature is 70℃. The investment method is to inject 1/3 hot water after putting the tea, gently shake it to make the tea absorb enough water and stretch it, and then inject it until it is seven minutes full of hot water.

The upper casting method and the middle casting method are suitable for delicate tea leaves, and there is another less used method, namely the lower casting method. Dropping method is different from the first two methods, which is to put tea leaves first, and then pour enough hot water into the teacup at one time. This method is suitable for ordinary green tea with poor tenderness.

4. Brewing time

Green tea is best brewed for three times before drinking, and the taste has begun to fade after the third soaking.

Brewing and drinking of green tea

Green tea is mostly made by picking tender buds and leaves, which has beautiful appearance and ornamental value after being brewed and absorbed. When making cups, you usually choose ones with good transparency and no patterns. When you brew in a glass, you should see Teamo first, then smell the tea, and finally taste the tea. Green tea can also be brewed in porcelain cups. The disadvantage is that you can only overlook te amo, but the taste and aroma are better than those in glasses. When making pots, you usually choose porcelain pots or glass pots.

Brewing green tea requires high water temperature, especially for delicate high-grade green tea. The water temperature is generally controlled between 75-85℃, and the water temperature is too low, so the aroma and taste of green tea are slightly poor, and its taste cannot be brewed. If the water temperature is too high, it is easy to cause the bitterness of tea soup to increase, and the soup is dark yellow, that is, put tea? Did you burn it? . Generally, when soaking in a cup, the ratio of tea to water is 1∶50, and the amount of tea can be appropriately increased or decreased according to the quality and taste of tea.

In addition, green tea pays attention to the way of throwing tea, which is divided into upper throwing method, middle throwing method and lower throwing method. Different cups are used for the same kind of tea, and the tea is poured in different ways, so its taste, aroma and other endoplasmic substances are also different. About the brewing of green tea. In life, the highest temperature at which a heated water dispenser can boil water is about 87℃, and green tea can be brewed directly. If boiling water is heated by hand-soaking and other appliances, it should be cooled for a period of time after boiling, and then brewing should be started when the temperature drops to about 80℃.

Matters needing attention in the preservation of green tea

Avoid humidity.

Green tea is a porous hydrophilic substance, so it has strong hygroscopicity and moisture regain. When storing green tea, the relative humidity is 60%, and when it exceeds 70%, mildew spots will occur due to moisture absorption, and then acidification will occur.

Avoid high temperature

The optimum storage temperature of green tea is 0-5℃. If the temperature is too high, amino acids, sugars, vitamins and aromatic substances in tea will be decomposed and destroyed, which will reduce the quality, aroma and taste.

Shan Zhi sunshine

Sunlight can promote the oxidation of green tea pigments and esters, and can decompose chlorophyll into pheophytin. Green tea is stored in glass containers or transparent plastic bags. Their internal substances will react chemically after being irradiated by sunlight, which will make the quality of green tea worse.

Four bogey oxygen

Chlorophyll, aldehydes, esters and vitamin C in green tea are easily combined with oxygen in the air. The oxidized green tea leaves will make the green tea soup red and deep, and the nutritional value will be greatly reduced.

Five terrible smells

Green tea contains macromolecular palmitase and terpenoids. This substance is extremely unstable in nature and can absorb odor widely. Therefore, when tea leaves are mixed with odorous objects for storage, they will absorb the odor and cannot be removed.

Health care function of green tea

1. anti-aging

Catechin is the essence of green tea, which can significantly improve the activity of SOD in human body, scavenge human oxidative free radicals, and prevent the harm of free radicals to human body, thus contributing to anti-aging.

2. Reduce blood lipids

Catechin can reduce the cholesterol content in blood and reduce the occurrence of arteriosclerosis. Flavonoids in green tea can resist oxidation, thus reducing the incidence of cardiovascular diseases. It is an essential product for daily health care of patients with hypertension, hyperlipidemia and diabetes.

Lose weight and lose weight

Theophylline and caffeine in green tea can reduce the accumulation of fat and have no destructive effect on probiotics in human intestines. Drinking green tea to lose weight is safe and reliable, and does not harm the body.
