Busch Ice delivers a sweet smooth finish and higher alcohol content that your average beer. 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. Our History: Busch is brewed with a blend of premium American-grown and imported hops and a combination of malt and corn to provide a pleasant balanced flavor. Since being introduced regionally in 1955 the Busch beer brand family has grown to become the top-selling value beer brand families. Busch Bavarian was the first beer brand Anheuser-Busch introduced following the repeal of Prohibition.
