How not to drink green tea?
Now you know who is contraindicated in green tea. However, it should be noted that before buying this product, you need to pay attention not only to its harm, but also how to use it correctly.

Brewing process
Making any tea drink, including green one, is called brewing. To do this, take about 2 g of dry matter and fill it with about 100 ml of boiled water.
It should also be noted that the brewing process can vary significantly depending on what kind of product you purchased. For example, high-quality tea uses a large amount of dry leaf, which can be brewed several times in a short time.
The preparation time of the drink and the water temperature are also different for different varieties of tea. The highest brewing temperature is 81-87 ° C, and the longest time is 2-3 minutes. As for the smallest value, it is 61-69 ° C and 30 seconds respectively.
As a rule, low-quality tea is brewed at higher temperatures and much longer than high-quality. It is from this observation that you can determine which product was sold to you in the store.
Finally, I would like to add that if green tea is brewed for too long and in boiling water, it will become astringent and bitter, regardless of its variety and quality.
