I thought it would be beneficial to have this discussion.
From my experience there is a huge smack you in your face hops presence with West Coast IPA's as opposed to a more subdued hop effect with East Coast brews. The West Coast has the convenience of the Pacific Northwest "C" hops (Centennial, Cascade, Chinook and Columbus) pine needle and grapefruit.
Whereas the East Coast has some European influences with the use of more crystal malts which leads to more body and darker beers. There is also the combining of American and English hops which are less bitter.
Dogfish Head's founder Sam Calagione states that "ounce for ounce I use as many hops as my Pacific Coast counterparts, including extra-bitter American hybrids such as Warrior and Amarillo."
Being an East Coast guy, I find the availability of West Coast beers to be limited but I am always searching for new examples of my favorite style of beer. I love IPA's, with lots of fresh hops.
What's your take on our American IPA's ?
