The difference separating the first and second breweries is larger than the difference separating #2 and #50 (on both craft and non-craft lists). <...> Put another way, the difference between 41 and 42 is on the order of a few thousand barrels; the difference between 1 and 2 is hundreds of thousands.
Jay Brooks looks at the overall top 50 and notes movement up or down. For example, both Sierra Nevada and New Belgium dropped a spot to #6 and #7, respectively. They were bumped by the rise of North American Breweries to #5. Aren't familiar with them? They're comprised of Dundee, Genesee, Labatt Lime, Magic Hat, and Pyramid. Goose Island fell to 48th from 18th, after selling its production brewery to Anheuser-Busch InBev.
#1 is Anheuser-Busch InBev, followed by Miller/Coors, Pabst (which actually does not own or operate a single brewing facility), Yuengling, and Boston Beer.
Local to me, Flying Dog, of Frederick, Maryland, rose two positions to #48. (Among 'craft' breweries, it sits at 26th.) No Virginia or Washington, D.C. breweries made the list.
