The legendary Boonville beer. The brewers of Anderson Valley had to conjure the High Priestess of Fermentation to help them formulate and create this rare hand-crafted ale. It is luxuriant and smooth, more than a little wild and it's bound to raise your spirits. Open the bottle and greet the High Priestess. You are Worthy. Brewed from malted barley, hops, water, demerara sugar and special trappist yeast. Never pasteurized or sterile filtered. Consistently judged one of the world's finest breweries.
