Dogfish Head founder Sam Calagione was eating pickles from Brooklyn Brine while drinking his 60 Minute IPA one day. The merging of the two flavors gave him an idea. The idea of a beer infused pickle collaboration. After round of beer sampling and hop research, Brooklyn Brine decided on Cascade hop oil. (Oils extracted from the hops leaves.) The pickle company is some pretty cool things with pickles, including barrel fermented pickles made in whiskey barrels.
