Beard beer is brewed with a yeast created from Brewmaster John Maier's beard. No need to freak out, brewers have used wild yeasts in beer making for centuries. John has had the same old growth beard since 1978 and for over 15,000 brews, so it is no great surprise that a natural yeast ideal for brewing was discovered in his beard. What does bread beer taste like? try it, we think you'll be surprised...
