This past weekend, I was sitting around with a couple of my closest pals offering small talk about our weekly adventures while we drank an assortment of beers keen to one another's liking. As I drank a variety of these beers, most with a strong alcohol content, a curiosity struck my mind. What is the strongest beer that is/was known to man. As soon as I got home from our gathering, I turned to Google to answer the question stuck in my head. The result: the now retired, Hair of the Dog's Dave. Dave is an English Barley Wine with a whopping 29 percent alcohol by volume. It was made in 1994, winning first place at the 1998 Tornado Barley Wine Festival. This high alcohol content was achieved by taking 300 gallons of beer and freezing it two times, creating just 100 gallons.
