MADISON, Wis. -- A New York City bar could get in trouble for allegedly selling a Wisconsin beer.

New York State Liquor Authority said its investigators confiscated 50 cases of Spotted Cow from the Mad River Bar & Grille in Manhattan on Nov. 6.

The beer is brewed by New Glarus Brewing Co. in Green County. Brewmaster Dan Carey said the beer isn't licensed for sale outside Wisconsin.

Liquor authority spokesman William Crowley told the Wisconsin State Journal that businesses selling alcohol in New York need to purchase their alcohol through a wholesale distributor. He said the bar could have its liquor license revoked for selling the beer and for not paying the appropriate taxes.

The bar, owned by Michael Mastellone, didn't immediately return a call and e-mail on Wednesday.
