I did some searching and didn't see any promising threads on this subject. My wife is allergic to bananas. I just brewed a hefe-weizen this week. I'm wondering if the same chemicals that produce the banana flavor and aroma are what she is allergic to, or if it's something intrinsic to the banana itself. Because she doesn't care for most of my homebrews, and I've been trying to do styles more to her liking, but it would be a shame if the one I made for her she can't drink anyway. Does anyone know anything about this?
