How often do y'all do this? I don't do it often, but those times that I do really crystalize that I prefer (e.g.) amber beer X to amber beer Y.
few times a year. Blind tasting is the only way to get the truth out. Made me realize how much I dislike local beers, because they stood out like crazy in a lineup of other IPA's, for example.
I would have to not know what the beers were I was tasting for it to be a true test.. But I've never done it, so I think I will try!
