In taking a look, I found (according to
http://www.oai.org/firstbuckeye/teams.html), that team 870 is/was sponsored by a brewery (caveat, I have no relation to this team, and the brewery is not on their current sponsor list as shown on TBA).
Team 4293
lists Lone Tree Brewing Company as a $2500-$4999 sponsor.
So, there are a few teams which are sponsored by breweries.
