I just wanted to give shout out to this stuff. Since i'v been using it no problems with beer, no off flavors, and so easy to use. I was nevous about the foam at first but i never fear the foam now rack right on top of it. Now if i didn't see that beautiful foam i would get worried. Star san best sanitizer in my opinion. Never fear that beautiful foam. 2 Mugs up for star san !!!!!!
