A reconstruction of the American lagers brewed by German immigrant brewers in the mid-to-late 19th century, before Prohibition (1920) interrupted the commercial tradition. Typically 4.5–6.0% ABV, pale gold to light gold. Built on six-row barley (the American-grown malting barley of the era) with 20–30% corn or rice adjunct, firmly hopped with Cluster-type American hops. More flavorful, more bitter, and slightly stronger than the modern mass-market American Lager that descended from it after Prohibition’s interruption weakened the tradition.

Origin
German immigrant brewers established American lager brewing in the mid-19th century, adapting continental lager techniques to American ingredients. They encountered a key problem: the high-protein, six-row barley available in the United States made for cloudy, heavy-bodied beers that didn’t resemble the pale Bohemian and Bavarian lagers back home. To dilute the protein, clarify the beer, and lighten the body, brewers began adding corn and rice adjuncts — a practice that became signature to American lager brewing. The resulting pre-Prohibition style was firmly hopped with American Cluster-type varieties, more bitter and more flavorful than the industrial American Lager that would later descend from it.
Prohibition interrupted the tradition. The Eighteenth Amendment was ratified on January 16, 1919 and went into effect the following year; the Twenty-first Amendment repealed it on December 5, 1933. By the time breweries resumed full operation, over a decade of shuttered capacity, altered consumer tastes, and industry consolidation had reshaped the American Lager profile toward lighter, less bitter, higher-adjunct products. The original pre-Prohibition character effectively vanished commercially. Homebrewers and later craft brewers reconstructed the style from archival recipes and period brewing literature, producing it under the historical-category banner — usually called “Pre-Prohibition Lager” in style-guideline sources and, in homebrew circles, “Classic American Pilsner” (CAP).
Notes
Commercial examples are rare; the style is most often encountered as a homebrew category or occasional craft seasonal. Modern American Lager is the direct post-Prohibition descendant — lower gravity, lower bitterness, higher adjunct, less hop character. Anchor’s California Lager, Schell’s Firebrick, and occasional small-craft Classic American Pilsner releases are the closest living commercial touchstones.
