There are a lot of arguments about if Kvass belongs, but I'd like to bring up and discuss the Japanese Happoshu. I can't find much information the style, but apparently it has to do with alcohol taxation laws in Japan. As such, it's not really a true 'style' of beer, meaning an IPA or pilsner or pale could fall into this taxation bracket. In fact, technically speaking, Kvass would be taxed as a Japanese Happoshu if sold in Japan due to its ingredient list. Further more, Happoshu is referred to as "the non beer beer" in Japanese slang. Personally, I don't mind keeping Japanese Happoshu as apart of the categories (or any of the recently mentioned categories), as it doesn't hurt anything to have an additional style listing aside from perhaps some having a difficult time earning a 'tick' in the style. It also gives a little notoriety to international beer culture.
