The following is an excerpt from John Palmer's newly updated book How to Brew:
"American IPA is all about hops; typically American 'C' hops such as, Chinook, Centennial and Cascade, but also the new Pacific varieties from New Zealand and Australia with their tropical fruit aromas. The Rushmore IPA recipe below is a West Coast IPA with just enough caramel and Munich malt to add complexity."
