I choose this kind of sencha for medical reasons. When i looked what sencha to chose, i found that this particular sencha has more cachetins than the other.s I believe it is true and will help me to fight with my health problem. I brew it as recommended...if i brew more time it is certainly getting bitter, which means i got max catechins which is my goal.
Advantages: I should add that O-Cha.com prises are affordable, much better than the other sites I checked.
