General colors mainly reflect the preservation conditions. If you don't pay attention to avoid light, the tea soup will deteriorate and weaken due to sunlight, and the taste will be boring. Normal oriental leaves should be clear in soup color: green tea is goose yellow, oolong tea is golden yellow, and black tea is dark orange red and Ming Che. If the color is dark and far beyond my description, it is better not to buy it even if the production date is near. In addition to water and tea, there are generally only two kinds of additives for oriental leaves, one is vitamin C and the other is sodium bicarbonate. The former is mainly an antioxidant, similar to dropping a little lemon juice on a fruit slice to prevent discoloration; The latter is to enhance the taste and provide a little refreshing feeling.
