Grain bill
- 8 lb 4 oz German Pilsner malt
- 1 lb 4 oz Vienna malt
- 8 oz Weyermann Barke Munich malt
Water
- 8.25 gal RO or distilled water—all strike water, no sparge
- 4.0 g calcium chloride
- 2.0 g gypsum
- 2.5 mL 88% lactic acid initially
- Target room-temperature mash pH: 5.25–5.35
These mineral additions assume RO or distilled water. Don’t copy them unchanged into tap water and blame the recipe.
Hallertau schedule
- 0.65 oz Hallertau Mittelfrüh at 4% AA — 60 minutes
- 0.85 oz Hallertau Mittelfrüh at 2.9% AA — 60 minutes
- 0.70 oz Hallertau Mittelfrüh at 2.9% AA — 10 minutes
Yeast and kettle additions
- 1 L active Lutra starter; pitch all at 68–70°F
- ½ tsp yeast nutrient at 10 minutes
- ½ Whirlfloc tablet at 10 minutes
- Optional: ½ tsp unflavored gelatin for rapid clearing
Mash and boil
- Heat treated water to 156°F and mash in all 10 lb of grain.
- Hold at 150°F for 60 minutes. Stir or gently recirculate during the mash.
- Optional: mash out at 168°F for 10 minutes.
- Lift, drain, and squeeze the bag. Target 7.3–7.5 gal pre-boil at roughly 1.037–1.039.
- Boil uncovered for 75 minutes, following the hop and kettle-addition schedule.
- Chill promptly to 68–70°F and transfer about 5.5 gal.
Fermentation
- Pitch the active starter at 68–70°F.
- Hold 68–72°F until terminal gravity.
- After gravity is stable, keep it warm another 24–48 hours.
- Drop to 50°F, then cold crash at 34–36°F for 24–48 hours.
- Add gelatin cold if using, then closed-transfer into a completely purged keg.
Carbonation and packaging
- Carbonate at 12 PSI and 35–36°F for 5–7 days, targeting 2.4–2.5 volumes.
- Keep it cold under serving pressure; every extra day helps the lager-like finish.
- For cans, chill the beer, lines, filler, and cans. Purge each can, fill from the bottom, cap on foam, and seam immediately.
- Store every can cold through the trip.
What actually happened
The festival batch started at 1.048 and finished around 1.003–1.004—drier and stronger than the original target. “Measured twice. Recalibrated anyway.”
