Dogfish Head Craft Brewery of Delaware is known for making some “off-centered” beers, but one of the styles they are still best known for is the IPA. 90 Minute IPA is an Imperial IPA that takes hop additions to the next level. Instead of having early, middle and late hop additions, the 90 Minute recipe, named for the length of the boil, has the brewer continuously add hops throughout the boil.
The result is a hop-forward imperial IPA with enough malt backbone to keep things balanced. Try your hand at brewing the clone and see how it stands up to the real thing!
