Precautions:

(a), can't brew for too long

If the brewing time is too long, tea polyphenols, lipids and aromatic substances in tea will automatically oxidize, which will not only make the tea soup darker in color, worse in taste and lower in aroma, but also lose its tasting value; Moreover, because vitamin C, vitamin P and amino acids in tea are reduced due to oxidation, the nutritional value of tea soup is also greatly reduced. At the same time, because the tea soup has been put on hold for a long time and is polluted by the surrounding environment, there are many microorganisms (bacteria and actinomycetes) in the tea soup, which is very unsanitary.

(2) Don't brew too much time.

Generally, there is basically no tea juice after brewing for 3-4 times. According to relevant tests, the water content of the first tea soup is 50%, the second tea soup is 30%, the third tea soup is 10%, and the fourth tea soup is only 1-3%. Repeated brewing will also leach some harmful components in tea, because trace harmful elements in tea are often leached at the end.
