From what I have read this beer was made long ago, but the store I work at just started carrying it about a month ago. I have heard a few different numbers, but 17.5% seems to be the popular suggested abv on this one. All I can say is soy-sauce and a ludicrously bitter chocolate flavor. Carbonation? I think not. I don't think I'll be buying another bottle, no matter how interesting the beer might be.
