I know all the brew books say to use a sterile fluid (alcohol) in the airlock during fermentation, but I only see this being an issue in certain situations. As long as the airlock fluid isn't being introduced into the fermenter, I don't see the big deal.... especially with a constant outflow of CO2. I've always used plain tap water in my airlocks and have never had a problem.
Anyone interested in convincing me to change my evil ways?
