But no matter what tea, the first brewing leaching amount can account for more than 50% of the total soluble substances. The second brewing of ordinary tea is generally about 30%, the third time is about 10%, and the fourth time is only 1-3%. From a nutritional perspective, Vitamin C and amino acids in tea are 80% leached after the first brewing, and more than 95% are leached after the second brewing.

This shows that general black, green, and scented teas are usually brewed three times. Oolong tea can be brewed more times because of the large amount of tea used when brewing; bagged tea processed from black broken tea is suitable for one-time brewing because it is easy to leach.
