I have always, always heard the quote attributed to wine, not beer. "Wine is proof God loves us, and wants us to be happy." I even quoted it several posts up as such.
And there was an anecdote from when Ben Franklin was working in construction as a very young man, and the German workers would always drink beer at lunch because they believed that it made them strong. Franklin, knowing exactly what goes into beer, commented that eating the bread was probably more effective at making you strong, since you're getting more of the grains in bread than in liquid beer, and its cheaper to boot.
