More and more craft breweries are joining forces with bands or artists or restaurants to produce specialty beers. Those of you in the Washington DC area may be familiar with the brewery DC Brau. DC Brau has produced two beers in collaboration with the popular ska band The Pietasters. The Hanson Brothers (yes, those Hanson Brothers) teamed up with Mustang Brewery to create a pale ale called Mmmhops (I promise this is true) so it wasn't so unusual to find a brewery teaming up with an ice cream company to try and make one of the greatest possible combinations of all time: brown ale and and salted caramel brownie.
