MillerCoors is proof that beer can make old foes new friends. Long-time rivals, UK-based SABMiller and US-based Molson Coors put aside their differences to merge their operations in the US and Puerto Rico in a joint venture, MilllerCoors. The #2 brewer in the US operates eight breweries and enjoys almost 30% of the domestic beer market. Its flagship brews are sold under the Coors Light and Miller Lite labels and import brews under Peroni and Molson Canadian. A division, the Tenth and Blake Beer Company, offers craft and import brews, such as Blue Moon, Foster's, and many others. MillerCoors also makes Sparks, a line of brand malt-based beverages. The company is 58%-owned by SABMiller with Molson Coors holding 42%.
