I know that we've got several guys on the forum who are getting married soon and this thread was inspired by them. I know how to work a picnic tap. It took me 1 pour to realize that I screwed up. The second pour was fine. I've made beer for weddings and the guests don't seem to get it. I have roommates who have been shown at least twice, and yet they still mess it up about once a week. Snap it on, snap it off, or you get foam. Is the best way to deal with crowds to have a designated person on those taps to make sure the guests aren't just drinking foam? Can you get away with pouring a dozen beers at a time and walking away for a while?
