A San Diego man is suing MillerCoors, claiming the company’s Blue Moon beer is not truly a craft beer.

Evan Parent claims MillerCoors deceived him by advertising their product, Blue Moon, as a craft beer produced in a small brewery when in actuality the product is made in large plants, according to the lawsuit.

The product is marketed as “artfully crafted,” but, Parents says, the product does not qualify as a craft brewery product.

“What this case is really about is people think they're buying craft beer and they're actually buying crafty marketing,” Parent's lawyer Jim Treglio told NBC7.

In the lawsuit, Parent says that despite the fact that MillerCoors has been brewing the beer for the past 20 years, “Defendant [MillerCoors] goes to great lengths to disassociate Blue Moon beer from the MillerCoors name. MillerCoors does not appear anywhere on the Blue Moon bottle,” the lawsuit claims.

By misleading the people who buy the beer, the lawsuit claims, they are able to charge up to 50 percent more for the product.

Parent said he cares about it because he is a beer aficionado and home brewer.

“It matters to me because I'm a craft brew fan...I take care in where I spend my money,” Parent said.

After learning the way the beer was made and marketed in 2012, he stopped purchasing the beer.

“When someone's deceiving me into giving them my money for the wrong reasons that's upsetting,” Parent told NBC7.

The class-action suit was filed in San Diego Superior Court.

A spokesperson for MillerCoors company says the lawsuit lacks merit.
