Busch Ice, introduced in 1995, undergoes an exclusive ice-brewing process, which takes the beer to a temperature below freezing. The ice crystals are then removed giving the beer its sweet, smooth finish and higher alcohol content.
Ice beer (Eisbock) was first brewed in Germany by accident during an unseasonably cold year. The bock beers brewed for spring froze, concentrating the flavor and increasing the alcohol content. Surprisingly the “new” beer was a hit and ice beer was born.
