title_body: What's the difference between a Triple IPA and a Double IPA?
upvoted_answer: A bit obvious, but it's just about more malt and hops (which results in higher ABV and IBU levels, off course).
  
  Particularly, I don't see it becoming a new style, as our palate has a limit when it comes to tasting bitterness and even smelling hop oils. I think we have already reached this limit sometime ago when Imperial IPAs were conceived. So, anything beyond that seems like a silly obsession to me, and probably the best that one can get from a "triple IPA" is to come up with a good Imperial/Double IPA with (maybe) more alcohol, nothing more.
  
  PS: Dogfish's 120 Minute IPA would be a quadruple IPA, then?
