Prohibition and Beer

The Great Experiment

The Eighteenth Amendment to the United States Constitution, ratified in 1919 and enforced beginning January 17, 1920, banned the manufacture, sale, and transportation of alcoholic beverages. The Volstead Act defined "intoxicating liquor" as anything above 0.5% ABV. American brewing, which had reached over 1,300 breweries by 1914, was effectively destroyed overnight.

Before Prohibition

Pre-Prohibition American brewing was diverse and regional. German immigrant brewers had established thriving operations in every major city: Anheuser-Busch and Lemp in St. Louis, Pabst and Schlitz in Milwaukee, Yuengling in Pottsville, Rainier in Seattle, Anchor in San Francisco. Each region had distinctive local breweries producing a range of styles: dark lagers, bocks, cream ales, steam beers, and porters alongside the increasingly popular pale lagers.

Survival Strategies

Of 1,300+ pre-Prohibition breweries, approximately 750 attempted to survive through alternative products:

Near beer — legal 0.5% ABV beer. The process was absurd: brew real beer, then dealcoholize it, destroying most flavor. Brands like Bevo (Anheuser-Busch), Famo (Schlitz), and Pablo (Pabst) sold poorly. Malt extract and syrup — sold ostensibly for baking, with a wink. Cans featured instructions for making bread that, if followed carelessly, might accidentally produce beer. Ice cream and dairy — Yuengling pivoted to ice cream (still sold today). Anheuser-Busch produced a yeast-based food supplement. Soft drinks — several breweries produced sodas and mineral water.

The Devastation

When Prohibition ended on December 5, 1933 (ratification of the Twenty-first Amendment), only about 160 breweries reopened. The others had sold equipment, lost expertise, or gone bankrupt.

The Post-Repeal Landscape

The surviving breweries faced a transformed market:

Consolidation — smaller, underfunded breweries could not compete with the national giants who had survived on alternative revenue. Decade by decade, the number shrank: 750 in 1935, 400 in 1950, 150 in 1965, 89 in 1978. Homogenization — to appeal to the broadest possible market (including consumers who had grown up without beer during Prohibition), breweries converged on a single style: light, inoffensive, adjunct-heavy pale lager. Adjunct usage — corn and rice replaced a portion of barley malt, lightening body and flavor while reducing cost. This was partly economic and partly taste-driven: a generation raised on sweet sodas preferred lighter, less bitter beer.

Lost Heritage

Prohibition erased America's brewing memory. Regional styles, family recipes, local yeast strains, and brewing knowledge accumulated over a century vanished. The diverse, vibrant pre-Prohibition beer landscape was replaced by a bland monoculture that persisted for fifty years.

The Long Shadow

Every aspect of American beer culture after 1933 was shaped by Prohibition: the three-tier distribution system (brewer, distributor, retailer — mandated to prevent the pre-Prohibition tied-house abuses), state-by-state licensing complexity, cultural ambivalence about alcohol, and the consolidation that reduced American brewing to a handful of identical products.

The craft beer revolution that began in the late 1970s was, in many ways, a recovery from Prohibition — a century-delayed restoration of the diversity, regionality, and quality that Prohibition destroyed.
