My SWMBO definitely supports my brewing habit. She is not a huge beer fan, but has her likes... pale ale, wheats, etc. She can't stand the smell of the mash & wort, but since I brew outside, she tolerates it pretty well.

I even go with her on occasion to the craft and scrapbook store (LSBS) which scores big points for sure.
