As promised, here's my original IPA recipe (based on Maui's Big Swell)
8.5 lb pale malt (62.3%)
2.0 lb 40L crystal (15.1%)
1.0 lb 10L crystal (7.5%)
1.0 lb munich I (7.5%)
1.0 lb flaked maize (7.5%)
1.0 oz Cascade
1.0 oz Citra
1.0 oz Magnum
2.0 oz Simcoe (keg hop)
So to step it up to a IIPA, my idea here is to do a small first wort addition, use about 6-9ml hop extract at the beginning and boil for 90 min. Then, as stated above, additions at flameout, whirlpool, dry hop and keg hop. I'll probably boost the base malt % and add some simple sugar (as per morticai's suggestion) to augment the fermentables so I can keep the body on the lighter side and get a little more booze in there.
I want to get just a little more sweetness than normal to balance the hops, alcohol and carbonation (shooting for about 1.080 or so.) So, what is a good target saccrification rest? Thanks for all the suggestions! Keep the conversation going!
