I heard this story a while ago and am trying to figure out if its true or not. Rumor has it that Thirsty Dog's 12 dogs of Christmas ale used to be the Great Lakes Christmas Ale. When the brewmaster of Great Lakes left, he took the recipe for Great Lakes Christmas ale with him to Thirsty dog brewing company and used it to make 12 dogs of Christmas. Since then Great Lakes has been recreating the recipe for its Christmas ale each year. However, I can't find anything on the internet to support this claim. Has anybody heard of this story and care to elaborate?
