InBev (then known as Interbrew) bought the Bass labels back in 2000.  The original Bass brewery itself in Burton-on-Trent is now a MolsonCoors facility and the Bass brewed and marketed in the UK is done at other breweries (Marston does the cask ale, the bottles/cans there come from an  A-B-InBev-owned brewery in the UK).
 
Besides Bass Ale, A-B-InBev is now also brewing Beck’s Beer (another InBev-owned brand) at it’s Baldwinsville, NY brewery.  The new Beck’s labels (some German-brewed packages are still on shelves in many markets) say “ORIGINATED IN BREMEN, GERMANY” and in smaller print “PRODUCT OF THE USA – BRAUERIE BECK & CO – ST. LOUIS, MO”
 
AB-InBev also brews some Alexander Keith brands in the US at Baldwinsville for the US market.  Keith’s is a Labatt-owned brand, and Labatt is yet another AB-InBev-owned brewing company.
 
Those with longer memories than the suits at AB-InBev will recall that Anheuser-Busch filed complaints with regulators back in the 1970’s when the Miller Brewing Company began brewing Lowenbrau under license in the US.
