Clone of Sierra Nevada Torpedo Extra IPA, the source of the recipe is http://www.eckraus.com/blog/torpedo-extra-ipa-clone-recipe-all-grain. I changed the recipe for my system. I really like Torpedo Extra IPA, it's a very nice IPA and a great value at Sam's club at around 14.50 a 12 pack. Sometimes it's cheaper than Sierra Nevada Pale Ale, doesn't make sense the IPA has a lot more ingredients to make the beer. Anyway I like it so I'll try this clone sometime.
