Duff Beer Homebrew Recipe
Share
Homer Simpson's beer of choice has powered countless evenings at Moe's Tavern, backyard barbecues, and couch sessions. Duff Beer is Springfield's lifeblood. Now you can brew it yourself.

This homebrew clone recipe creates an American adjunct lager similar to what would flow from the taps at Moe's. Light, crisp, and designed for maximum drinkability.
Quick Facts
- Brew Time: 4-6 hours
- Fermentation: 2-3 weeks
- Conditioning: 2-4 weeks
- Difficulty: Intermediate
- Batch Size: 19 liters (5 gallons)
- ABV: 4.5-5%
Ingredients
Grain Bill: - 3.5 kg Pilsner malt - 0.5 kg Flaked rice (adjunct) - 0.25 kg Flaked corn (adjunct)
Hops: - 15g Cluster hops (60 minutes, bittering) - 10g Saaz hops (15 minutes, flavor)
Yeast: - White Labs WLP840 American Lager yeast (or Fermentis W-34/70)
Other: - 1 tsp Irish moss (15 minutes, for clarity) - Corn sugar for priming (if bottle conditioning)

Method
Mash:
Heat 15 liters of water to 67°C. Add grains and maintain temperature for 60 minutes. The adjuncts (rice and corn) add the light body and crisp finish characteristic of American lagers.
Stir occasionally. Check conversion with an iodine test if you're particular about these things.
Sparge:
Raise mash temperature to 76°C for mash-out. Sparge with 12 liters of 76°C water until you collect approximately 25 liters of wort.
Boil:
Bring wort to a rolling boil. Add Cluster hops at the 60-minute mark. Add Irish moss and Saaz hops at the 15-minute mark.
Total boil time: 60 minutes.
Cool and Ferment:
Cool wort to 10°C as quickly as possible. Lagers need cold fermentation.
Transfer to fermenter and pitch yeast. Ferment at 10-12°C for 2-3 weeks. This slow, cold fermentation creates the clean lager character.
Lager:
After primary fermentation, reduce temperature to 2-4°C and lager for 2-4 weeks. This conditioning phase smooths out the beer and develops clarity.
Package:
Bottle with priming sugar or keg and force carbonate to 2.5-2.8 volumes CO2.
The Duff Character
Real Duff Beer (the fictional version) is an American adjunct lager. Think Budweiser, Coors, or Miller. These beers prioritize drinkability over complexity.
The adjuncts (rice and corn) lighten the body and create that signature crispness. The hop profile is subtle, just enough to balance the malt sweetness.
The result should be golden, clear, and extremely sessionable. Homer drinks multiple Duffs per sitting. The ABV and flavor profile accommodate this.
Troubleshooting
Too dark? Your pilsner malt may have been over-modified. Use a lighter base malt or reduce specialty grains.
Not clear? Extend the lagering phase. Cold conditioning develops clarity over time. Irish moss during the boil also helps.
Off flavors? Likely fermentation temperature issues. Lagers need consistent cold temperatures. Warm fermentation creates fusel alcohols and other unwanted compounds.
Not enough carbonation? Use more priming sugar or increase CO2 pressure. Duff should be well-carbonated.
Variations
Duff Lite: Reduce grain bill by 20%. Add more rice. Target 3.5% ABV.
Duff Dry: Use 100% pilsner malt, no adjuncts. Slightly more hop presence.
Duffenbrau: German-style treatment. Use all pilsner malt and noble hops only.
Note: In the show, Duff, Duff Lite, and Duff Dry all come from the same tank. Your variations can differ.
The Label
Half the fun of brewing Duff is the presentation. The iconic red and white label is simple to recreate. Print your own labels featuring the Duff logo for authentic bottles.
For legal events only. Don't sell your Duff.
The Lore
Duff Beer is Springfield's dominant beer brand. The mascot is Duffman, an overly enthusiastic spokesman with questionable personal boundaries. The brewery tour reveals that Duff, Duff Lite, and Duff Dry are all filled from the same pipe.
The Seven Duffs are a parody of the Seven Dwarfs, used in Duff marketing. Their names are Tipsy, Queasy, Surly, Sleazy, Edgy, Dizzy, and Remorseful.
Homer's consumption of Duff is legendary. It's his primary food group after donuts.
