Trying to tap into that market would be a difficult task for anyone, even for SABMiller (NASDAQOTH: SBMRY), the world's second largest brewer, which is why it undoubtedly figured that by hooking up with Canada's biggest operator, Molson Coors ( TAP 0.53% ), with 39% of the beer market, it would have an easier time of getting better distribution. Their MillerCoors joint venture was created in 2007 and mainly distributes beer in the U.S. and Puerto Rico, but it also allows Molson to market and distribute certain Miller brands in Canada.
