The Coors Brewing Company managed to survive Prohibition relatively intact. Years before the Volstead Act went into effect nationwide, Adolph Coors with sons Adolph Jr. , Grover, and Herman established the Adolph Coors Brewing and Manufacturing Company, which included Herold Porcelain and other ventures. The brewery itself was converted into a malted milk and near beer production facility. Coors sold much of the malted milk to the Mars candy company for the production of sweets. Manna, the company's non-alcoholic beer replacement, was a near beer similar to current non-alcoholic beverages. However, Coors and his sons relied heavily on the porcelain company as well as a cement and real estate company to keep the Coors Brewing Company afloat. By 1933, after the end of Prohibition, the Coors brewery was one of only a handful of breweries that had survived.
