Guarana is busting out all over in the States, but before it became par for the course for energy drinks to have it in their ingredients list, guarana was in drinks coming out of Brazil. It was at a Brazilian grocery store (as in one that sells Brazilian stuff--I have sadly not snuck away to Brazil recently) that I came across these two by Matte LeÃ£o. I don't speak Portuguese and these bottles came with very little English on them, so if I make assumptions and get it wrong, don't mock me too viciously.
First up, I tried the Matte LeÃ£o + Guarana. From what I could taste, we're talking mate tea plus guarana. And my reading of the ingredients list seems to support that. And real sugar, so that's good. I don't believe there's fake sugar in here, although it could be on the ingredients list and how would I know? The guarana-laced tea taste was very interesting, especially since it seemed to have a bit of caramel in there as well, and it had a bit of a kick to it. The yerba mate plus guarana combo was a nice one.
If you want a standard guarana drink, then the Power isn't a bad pick. But if you want something a little different and, surprisingly, with more power than the Power, the standard +Guarana variation is the way to go.
