Beechwood Aged
A method to complete the lagering process quickly by allowing a greater surface area of yeast to be exposed to the circulating beer.
Although touted prominently in Anheuser-Busch advertising, beechwood aging is not like wood or barrel aging in that the purpose is not to add flavor or complexity to the finished product. In fact, the beechwood is boiled extensively in sodium bicarbonate before use to remove any flavor.
