biggest "american" brewer?

Now that InBev is buying Anheuser-Busch, the largest US-based brewing company will be... Boston Beer Company (Sam Adams). Miller is now part of London-based SABMiller, and Coors is part of Molson (Pabst is also larger, in some measure, but it's really just a brand name company that has things brewed by Miller). This probably doesn't mean much in the grand scheme of things, but it's interesting.
