Yeah, it's black. Green tea tastes a lot more vegetably, but I for one prefer it. If you find the taste off-putting, try an oolong. It's semi-fermented, so it's basically halfway between green and black. There is a lot of variety between them too, so you can get one that is closer to green, or closer to black.
In other news, I'm nearly out of matcha, and I think that I may end up freaking out. I can't make it to the Asian market until Friday, and I sure as hell am not going to pay $30 for a 30g tin.
