Not bad but not great. The first time I tried this, I was using way too much leaf, and it was so vegetal and astringent that I could barely finish the cup. Today, I actually followed directions, and it was much lighter, and much less like drinking a glass of seaweed puree. i don’t have a good way to check the water temp here at work, so I’ve been winging it – I have noticed that the hotter the water I’ve used, the stronger both in flavor and in astringency.
I think this would work for you if you like strong, simple green teas.
