The CEO of the world's third-largest beer brewer says this will be a year of transition for his company. Molson Coors, based both in Denver and Montreal, has completed a major acquisition.

Molson Coors traces its roots to some pretty well-known founders. John Molson of Canada's Molson Brewing, Frederick Miller of Miller Brewing and Adolph Coors of Coors Brewing. Those heritage beers are now owned by a company that has dozens of other brews and is looking to expand into new markets around the world.
