120 Minute IPA is not cheap and it's not easy to get. Dogfish Head releases it several times a year and it sells out quickly. Is it worth the effort of tracking down a 4-pack? It's called an IPA, but at 18% it's not like most IPAs. Does it even taste like an IPA? So many questions about a beer that we've wanted to review for a long time. It was so special that I even wore a tux for the occasion.
