California Common is one of the few truly American historical beer styles, and it’s one I have a personal connection to, I grew up in Northern California and Anchor Steam was the first beer I understood as having a specific character worth paying attention to. The style’s origin is practical: San Francisco brewers in the Gold Rush era needed to ferment beer without ice, so they used lager yeast at ambient temperatures, which in San Francisco’s climate meant 55–65°F. The result was a hybrid character, the body and malt profile of a lager with a slight ale fruitiness from warmer fermentation. Here’s how to brew it authentically.
Style profile and historical context
California Common (BJCP 19B) targets 1.048–1.054 OG, 30–45 IBU, 10–14 SRM, and 4.5–5.5% ABV. It’s characterized by a firm, persistent malt character (toasty, caramel), assertive Northern Brewer hop bitterness and woody/herbal hop flavor, and a clean fermentation with a slight fruitiness that’s more lager-like than ale-like. The amber color comes from crystal malt and the Northern Brewer hops provide a distinctive woody, minty hop character unlike most American hop varieties. Anchor Steam is the style’s defining commercial example, and the trademark means the style must be called “California Common” rather than “Steam Beer” by other producers. It’s a robust, malt-forward amber lager hybrid with character that stands out clearly from both standard lagers and ales.
Grain bill, hops, and water
Grain bill: American 2-row (80–85%), Crystal 40 (8–10%) for caramel sweetness and amber color, Crystal 80 (3–5%) for deeper color and raisin notes. Some recipes add a small amount of Victory or Biscuit malt (3–5%) for toasty malt depth. Hops: Northern Brewer is the defining variety for California Common, its woody, minty, herbal character is specific to the style and isn’t well-replicated by substitutes. Use Northern Brewer for bittering (30–45 IBU) and a late addition (15 minutes) for hop flavor. Dry hopping with Northern Brewer (0.5 oz per 5 gallons) is optional but adds the characteristic aroma. Water: moderately mineralized, similar to a balanced pale ale water profile, sulfate 100–150 ppm, chloride 75–100 ppm.
Yeast and fermentation
Wyeast 2112 (California Lager) or White Labs WLP810 (San Francisco Lager) are the specific strains developed for this style, both are lager strains that ferment cleanly at 58–65°F without the refrigeration required for standard lager yeast. Ferment at 58–62°F for the characteristic clean-but-not-lager, fruity-but-not-ale character. At lower temperatures (55–58°F), the fermentation slows and produces a cleaner, more lager-like result. At higher temperatures (65°F+), more ale-like fruitiness develops. The traditional 58–62°F range is the sweet spot for authentic California Common character. No lagering required, this is a warm-fermented hybrid that’s ready to drink in 3–4 weeks. Carbonate at 2.4–2.8 volumes CO2.
Common Questions
Can I substitute a different hop variety if I can’t find Northern Brewer?
Northern Brewer is genuinely hard to substitute for California Common because its specific woody, minty, herbal character defines the style’s hop profile. Reasonable substitutes that share some characteristics: Perle (similar herbal character, slightly more floral, the best substitute), Magnum (neutral bittering substitute, loses the woody character), or Chinook (resinous, woody notes, more pine than mint, changes the character noticeably). Centennial and Columbus are too citrus/resinous to substitute accurately. If Northern Brewer is unavailable locally, order it, it’s widely stocked at online homebrew shops (Northern Brewer Hops, MoreBeer, Yakima Valley Hops) and worth getting right for this style. The style’s distinctiveness is tied to Northern Brewer in a way that few other styles are tied to a specific hop variety; substituting significantly alters the result.
