Barrel Aged Beers represent the height of a brew masters talent and passion. The impartation of long-term wood aging on fine beer makes for the most complex expression possible in terms of the aroma, taste, mouth feel and finish of these special beers. Barrel Aged Beers are truly a connoisseur's choice. The Spiegelau Barrel Aged Glass is the result of a two year development project in partnership with the brew masters of four of the world's great producers of Barrel Aged Beer: Great Divide Brewing Company of Denver, Colorado; Green Flash Brewing Company of San Diego, California; Uinta Brewing Company of Salt Lake City, Utah and Cigar City Brewing of Tampa Bay, Florida. We hope that you enjoy using this glass for your most special beers!
