Which beers contain wheat?
You can try checking out this website, http://www.progressivegrocer.com/progressivegrocer/profitguides/beer/v2/news/new_products.jsp. They have an online beer guide, which tells you both the new and old beers that are available. Not only does it give you that information, but it also gives you the ingredients (flavors) that each beer contains, as well as how its brewed, etc. So in there you should be able to find which beers contain wheat.
