The dominant commercial American beer style of the 20th century — a pale, highly carbonated, lightly hopped lager with a substantial adjunct grain bill (typically 20–40% rice or corn). Typically 4.2–5.3% ABV, very pale gold to light gold. Crisp, clean, and highly sessionable, with very low bitterness and minimal hop character; the style prioritizes neutral drinkability over flavor complexity. Descended from the Pre-Prohibition Lager tradition, but lighter in body, lower in bitterness, and higher in adjunct than the pre-1920 predecessor.

Origin
American Lager descends from the Pre-Prohibition Lager tradition established by 19th-century German immigrants, whose breweries used six-row barley with corn or rice adjunct. Prohibition in the United States (1920–1933) wiped out most commercial breweries, and when the industry was relicensed in 1933 the surviving companies pivoted toward lighter, more heavily adjuncted beers — the post-repeal landscape produced light-bodied golden lager and little else. Through the mid-20th century the category consolidated into a small number of dominant brands (Anheuser-Busch, Miller, Pabst, Schlitz, and later Coors) that aggressively marketed the lighter, crisper, less hopped profile, and the style became the global commercial template for mass-market lager. American Light Lager, a lower-calorie, lower-alcohol variant, emerged in the 1970s and overtook the standard-strength version in US market share by the 2000s.
Notes
The 2021 Beer Judge Certification Program guidelines cover the same style as 1B “American Lager.” The 2026 Brewers Association guidelines separate American-Style Lager (Standard, this entry) from American-Style Light Lager (lower calorie/ABV), American-Style Premium Lager (slightly maltier), and American-Style Specialty Lager (flavored variants). Pre-Prohibition Lager — the pre-1920 predecessor, carried as a distinct entry in both source guideline systems — is higher in bitterness, lower in adjunct percentage, and more hop-forward in character.
