DENVER – A California man has filed a class action lawsuit against the makers of “Blue Moon” claiming that he was unaware the product was made by beer conglomerate MillerCoors.

Blue Moon began brewing in Colorado in 1995 and has become one of the best selling beers across the United States. The company has marketed the beer as a Belgian-style wheat ale that is “artfully crafted.”

The lawsuit alleges the beer is mass produced and is not defined as a craft beer because it’s brewed in quantities of several million gallons each year.

The company responded to FOX31 with a statement:

“MillerCoors is tremendously proud of Blue Moon and has always embraced our ownership and support of this wonderful brand. The class action filed against MillerCoors in California is without merit and contradicted by Blue Moon Brewing Company’s 20-year history of brewing creative beers of the highest quality. There are countless definitions of “craft,” none of which are legal definitions. We choose to judge beer by the quality, skill and passion that goes into brewing it. Back in 1995, Keith Villa, Blue Moon’s founder and head brewmaster had to work extremely hard to convince people to try his cloudy, Belgian-style beer. Today, MillerCoors is proud that Blue Moon has invited millions of drinkers to try something new, while helping pave the way for the current explosion of creativity in the brewing community.”
