Not as Yerba Mate flavor as I expected. I was hoping to do all 12 of these at once, but it's not going to happen since we can't really move them with us. I'm hoping to find 8-12 in NY, and just may cry without finishing this series.
Anyway, for the beer, it was not overpowering but it wasn't what I'd decide to have if there was a pending apocalypse which I presume must involve zombies.
Check out the brewery's site for more info.
See if it's distributed near you and what others think at Rate Beer.
