Long time reader/lurker, and first time poster.
Thought I'd chime in and say that I have tried 100% wheat, and its one of my best drinkers. I used 100% red wheat, and Kellerweiss that I cultured from the bottle. I do BIAB so I didn't need the rice hulls. The taste is a little different than with a portion of barley (at least in mine) in the sense that the beer is much richer. I'm not sure why, but process wise I seem to get slightly less (from normal 75% down to 70%) efficiency with this brew. But, I don't know if that is common with large wheat bills or just my own quirk. I really love the rich taste of the beer though. Definitely try it if you like.
