title_body: Is overcarbonated IPA an IPA or a different style?
upvoted_answer: I would argue that an overcarbonated IPA is still an IPA. IPAs are characterized by the intense hoppy aroma, a malt backbone, and color. The carbonation level isn't referred to in style guides, generally.

  What I believe you're doing is creating a slightly more sour IPA. With more dissolved CO2 in the beer, you're creating slight amounts of carbonic acid, and acids make things a bit more sour. Seems like a pretty cool variant of an IPA, actually.
