They also own Sharp's Brewery (of Doom Bar fame) which I never knew: http://www.molsoncoors.com/en/Brands/Signature%20Brands/Doom%20Bar.aspx http://www.molsoncoors.com/en/Brands/Signature%20Brands/Doom... In that case they simply bought the brewery which was already successful and produced a few award winning ales.
