So for the last 3 years I make this American Wheat based on the BCS recipe, which is roughly 50% pale malt, 30% rye, and 20% wheat, lightly hopped at 60m and flameout with a combo of Willamette, Centennial, Cascade, Hallertauer, or whatever I feel like, to about 20-25 IBUs. I aim for it to finish around 1.010-1.012, with ABV around 5.5% to 6.0%. It's a nice spring/summer beer. Anyways for my buddies I make a sort of novelty/jokey label touting it as healthy multigrain high-fiber beer, blah blah blah.
So I get to thinking as I brewed it a month ago, what can I add to make it really "multigrain". Obviously I could toss some oat malt or flaked oats in there. But who's put really weird grains in their beers, and what were the results? I'm thinking maybe millet or buckwheat? Flax is a little oily, but? I could do corn; flaked is boring so what about popcorn? Or spelt or bulgur wheat? I'm open to experimentation if it won't totally ruin a batch.
Crazy ideas welcome!
