Black Water Imperial Stout. The dark waters of the Okefenokee Swamp in North Florida have garnered fame as North America's largest blackwater swamp. Named after this ominous place, our imperial stout is born from dark grains and balanced with hops of english ancestry for big flavor in a slow moving way. With a rich, heavy body, and strong overtones of dark chocolate, this is a stout to satisfy the swamper in all of us....especially when the sun goes down.
