man this kombucha stuff sounds nasty. interesting how it seems like it's originally japanese, kombu being a type of seaweed commonly eaten and cha being tea. but apparently it has nothing to do with japan or seaweed, instead some nasty moldy tea. strange.

oolong tea is low in caffeine and is common in asia as an "evening tea", i.e. it won't keep you up buzzing. it's tasty too.
