Many people perceive green tea and as a medicinal product, because it has a property to reduce blood pressure, being hot and raise it if the drink is cold. Green tea has proven properties to reduce cholesterol levels, combat fatty sediments, stimulate the work of the immune system, etc.
As you know, tea, whether it is green, black or white, is all the same tea. The difference only in its processing and storage. If you go to a specialized store, you can see many varieties, both green and black tea. The taste of tea is changing from strong to gentle due to the technology of production when choosing raw materials - kidneys, young green top leaflets or completely rided leaves. The highest quality tea is obtained from the first sheets of tea bush.
It is believed that the most useful and demanded teas are grown in China and produced in Japan. If we compare green and black teas, and rather the technology of their manufacturing, then in the production of green tea, more delicate processing of leaves is used, therefore in green tea is much more benefit than in black.
Fermentation and Further Tea Processing
The fermentation of tea depends on whether it will be black or green, red or white. Fermentation of tea is the degree of oxidation of tea leaves during their drying. It is believed that the less fermented tea, the more preserves the original herbal taste, the aroma of fresh greenery and useful substances.
From further processing of tea leaves (twisting) depends, how long its natural properties will retain and how high quality it will be boiled. Further drying of tea is needed to remove moisture residue, after which the finished tea product appears dark color, resistant aroma and soft taste. Store such tea only in hermetic opaque packaging.
Useful properties of green tea

- Microelements: potassium, copper, iodine
How to brew green tea
The preservation of the beneficial properties of the tea depends on how much we can brew it correctly.

- Take one teaspoon of tea at the rate of one middle cup and pour it into the kettle
- Fill tea with purified water, which is not brought to a boil (somewhere 80 degrees) and brew no more than three minutes - this is the first welding
- Fill hot water a second time, but now insist for 30-40 seconds longer than before
- This brewing of the same portion of green tea can be carried out up to 5-7 times and its properties do not deteriorate. It is said that the third welding is the most useful and tasty with this preparation of green tea.
Second way
- For tea cooking, we use a porcelain or clay kettle and a pile
- In the kettle we fall asleep dry tea at the rate of one teaspoon for a portion
- Pour strongly hot water and after insisting a couple of minutes
- Pour tea in the pile
- Cut the teapot from the food
- We repeat this manipulation several times
With this brewing tea "breathes" - is saturated with oxygen and cool down a bit. After 5-7 transfusions from the kettle in the pile and back, the tea lay down on the cups and enjoy the drink.
It is said that the invigorating effect of tea has after a two-minute brewing, but if you brew it 5 minutes, then tea becomes soothing. If you brew tea for longer than 10 minutes, then you can get a bitter welding.

This tea is cheerful and has a more sparing effect on the nervous and cardiovascular system, as it contains less caffeine. Green tea contributes to a better absorption of milk and is distinguished by a soft and pleasant taste.
But drinking such a drink is recommended only 30-40 minutes after meals. This is due to the fact that the milk protein, connecting with the enzymes of tea, is able to break the digestive process.

Nevertheless, if you like the taste of green tea with milk and this drink does not cause discomfort, then drink it to health!
