Mexican Vienna Lager is one of the most historically interesting styles in brewing, an Austrian amber lager transplanted to Mexico in the 1860s by European immigrant brewers, then kept alive in Mexican commercial brewing long after the style died out in its homeland. Modelo, Dos Equis Amber, and Negra Modelo are the widely available commercial examples. I’ve brewed this style a dozen times and it’s become my most requested beer by people who “don’t usually like homebrewed beer”, the toasty malt sweetness and clean lager character make it broadly approachable while still being interesting to someone who knows what they’re tasting.
How Mexican Vienna Lager differs from German Vienna Lager
Mexican Vienna Lager (BJCP 7B) shares the same historical roots as German Vienna Lager but has evolved distinctly. Key differences: Mexican examples are generally lower in alcohol (3.5–5.0% ABV vs 4.7–5.5% for German Vienna), slightly lighter in color (6–14 SRM vs 9–15 SRM), and often include corn (maize) as an adjunct (10–20% of the grist), a common ingredient in Mexican commercial lagers that lightens body and reduces cost. The malt character is still toasty and bready but slightly softer and cleaner than German Vienna. IBU range: 10–20, lower than German Vienna’s 18–30. The adjunct addition is the defining differentiator, a Mexican Vienna without corn can still be excellent but won’t taste like the commercial models.
Grain bill and brewing process
Grain bill: Vienna malt (50–60%), flaked maize (15–20%), Munich malt (10–15%), and Pilsner malt (10–15%). The flaked maize doesn’t require a cereal mash, it’s pre-gelatinized and converts in the main mash with the malted grain enzymes. Use a mash rest at 148–150°F (64–65°C) for a dry, clean wort that lets the malt character speak without excessive body. Hops: Hallertau, Saaz, or Tettnang at 10–18 IBU, single bittering addition. The hop character should be nearly invisible, Mexican Vienna is a malt-showcasing beer where hops are purely structural.
Fermentation and lagering
Lager yeast appropriate for clean, neutral character: Fermentis W-34/70, Wyeast 2112 (California Lager, which ferments clean at slightly warmer temperatures, 58–62°F), or White Labs WLP940 (Mexican Lager, specifically marketed for this style). Ferment at 50–54°F for standard lager yeast or 58–62°F for W-34/70 or WLP940. Diacetyl rest at 60°F for 48 hours. Lager at 34–38°F for 4–6 weeks, Mexican Vienna benefits from lagering but doesn’t require the extended conditioning of stronger lager styles. The finished beer should be very clean, with the toasty malt character clearly present but not overwhelming, and corn sweetness integrated into the malt profile rather than tasting separately “corny.”
Common Questions
Can I use rice instead of corn in Mexican Vienna Lager?
Rice and corn are both traditional adjuncts in light lagers and both lighten body, reduce color, and dilute malt character, but they contribute different flavor profiles. Corn (maize) adds a subtle sweetness that complements the toasty Vienna malt character in Mexican lager and is the historically authentic adjunct for this style. Rice produces a cleaner, more neutral adjunct contribution, it’s the adjunct used in American light lagers and Japanese rice lagers. Using flaked rice in a Mexican Vienna produces a cleaner, drier result than flaked corn; using flaked corn produces the slight sweetness that characterizes commercial examples like Negra Modelo. For the most authentic Mexican Vienna Lager, use flaked corn (also sold as flaked maize at homebrew shops) rather than rice. Both require no separate cereal mash when used in flaked form.
