I started to choose my teas lately also based on the fact how I feel after drinking such a tea soup. In case my mind is disturbed, in case I get a rash suddenly on my face, the tongue is somehow stingy, I rather avoid such teas. A clean tea taste is pure and refined. It is like drinking a water out of a mountain spring. The taste is so pure that you feel the cleaness and freshness of it. The overall feeling of the body and mind after drinking such teas is light, slightly exalted and comfortable.
