3 Floyds just released their collaboration with Surly at the brewery for $15 a bottle (750 ml). Limit two per person. See description below. "This collaboration beer between Surly and Three Floyds can best be described as an Imperial Brett IPA fermented with the unique strain of yeast Brettanomyces Lambicus. This yeast creates earthy barnyard notes along with pineapple-cherry pie aromas and flavors. Of course with the "IPA" style it's hopped heavily. Simcoe and Chinook are the culprits for the "Cat peed on the Christmas tree" aroma." Cheers!
