In January, Seventh Son Brewing and Rockmill Brewery teamed up to create a collaboration Belgian stout. The partnership has resulted in not one, but three variations on a beer they're calling Urban Cowboy-all of which come out this week. Rockmill's version is available on store shelves, while Seventh Son unveils its Urban Cowboy at a release party at the brewery tonight at 7 p.m.

The idea was to let each brewery show off its unique style. Each brewery started with the same base recipe, then added minor variations. Rockmill started with a base pilsner malt, their yeast and Belgian rock candi sugar. While Seventh Son used their own pale ale malt as a base, adding a blend of their house and Rockmill yeast, and then an American-made Belgian candi syrup.

At tonight's release party, guests will be able to buy both Urban Cowboy iterations, plus Urfa Cowboy, a third version infused with Urfa chilies and cacao nibs by Seventh Son.

Last night, I had a chance to sample Rockmill's version-bottled in true Rockmill style with a cork and a cage. It drank like a stout; creamy and smooth and without the usual thickness. It had just enough bite with a slightly sweet finish. I'm looking forward to trying the other three in the lineup. –Beth Stallings
