I've recently been involved in an on-going discussion about the cleaning spritzers at craft beer bars. I've always been under the impression that all glasses should be clean and air-dried before being filled with beer. Why are so many bars going to this spritzer to secondarily clean glasses? I realize that not much water is left in the glass after this process, but it seems to me that if I'm paying $8 for a 10oz pour of BA batch 9k at my local bar, i don't want ANY water in my glass. Not to mention most of these spritzers also chill the glass, and typically I'm trying to warm the beer i order before i drink it. Any thoughts? Anyone with industry expertise that can give me an argument to either side?
