A connection of mine on a different site asked if anyone was familiar with a tea called Gyokucha. It's a Japanese tea that looks somewhat like Gunpowder. He wanted to know if it was a kind of Japanese tea that's trying to be a Japanese version of Pinhead. He is the CEO of a tea company in Japan, and says that while he and his people were discussing it, they noticed that the rolled leaves were about the size of peanuts, so they started munching on them. He also mentioned that doing that wasn't a good idea if you're sensitive to caffein. Can anyone tell me anything about this tea?
