The pub brewer for Goose Island, Jared Rouben, is actually a big Primus fan, so that was the inspiration. It is also a collaboration brew with Longman & Eagle, designed to "cut the fat" in their pork dishes. I'll give it a try next time I hit Goose Island. I really enjoy the work Goose Island has been doing with their Belgians, so I'm sure it's good.
