Busch Ice has a rich, smooth taste with exceptional drinkability and a slightly sweet finish. Busch Ice undergoes Anheuser-Busch’s exclusive ice-brewing process, which takes the beer to a temperature below freezing. This leads to the formation of ice crystals in the finishing process, which help create its rich, smooth taste. Ice beer is rumored to have been developed by accident in Germany during Oktoberfest celebrations. A particularly cold year froze the celebrated bock beers, which are traditionally brewed for spring, and a new taste was noticed by the drinkers.
