I have a basic Malt bill I use and then mess with the hops every time. Sometimes I hop burst, sometimes I'll do the more standard 15, 10, 5 minute additions. Sometimes fwh...you get the Idea. Then I'll adjust the Magnum addition to get the ibus where I want them, usually right at 40 ibus.
90% us pale malt
10% crystal 40
Bittering hop - Magnum
Flavor aroma hops - typically centennial augmented by something else. Right now my mix is zythos and centennial. I really like a three hop combo of centennial, Amarillo and chinook.
