It's great! I got 20 little black tuo chas (100g) from Stash which I later realized was the most expensive place I could have bought 'em. But I brewed a few cups and I really enjoyed it! It brewed up sort of a mahogany color, dark purplish brown, and it has a taste that I can only describe as "extremely vegetal" .. you have no doubt that what you're drinking is from a plant. But it has no lingering aftertaste, it finishes clean and is very friendly and drinkable. Very pleasant! I even brewed up some for two other people who drank their entire mug-fulls and said it was strange but not bad.
I think green is nicer for casual drinking, because currently it's almost like I have to psych myself up for Pu-erh, but I'll definitely be buying it again (hopefully from a different retailer!)
