What effect does longer steeping times have on caffeine, theanine and catechins?
Longer steeping times result in more ingredients being extracted. If you want more healthy ingredients in your cup, you may want to brew a little longer. The important words are a “little longer”; steeping too long will make the tea bitter. Japanese tea is unique in that ingredients are extracted faster than the other teas. This is because it is processed through rolling and kneading which breaks the fibers in the tea leaves. The broken fibers give up their ingredients easily. Generally, 80% of ingredients are extracted in the first cup with our recommended brewing times. Try adding seconds to your brewing time until the tea becomes too bitter for your taste then remove several seconds. At that brewing time you have probably depleted the leaves of their ingredients.
