Workflow
Execute Brew Day
4-6 hoursMash at calculated temperatures, sparge, boil with hops, and cool wort. Measure original gravity before pitching yeast.
Monitor Fermentation
1-3 weeksTrack fermentation progress, measure final gravity, and calculate actual ABV and attenuation.
Review the Source-Owned Packaging Addition Record
30 minutesReconcile one retained package-conditioning mass plan only after responsible owners approve the batch, product, fermentation, package rating, and exposure-condition evidence.
Evaluate and Refine
2-4 weeks conditioningCalculate final ABV, assess mash efficiency for next batch, and adjust grain bill or process accordingly.
Tools Used
- Source-Owned Mash Water BalanceReference
Reconcile one retained source-owned mash/pre-boil water balance without selecting recipe or process.
- Ratio CalculatorSupporting
Balance grain bill ratios for target color and body.
- Homebrew ABV CalculatorPrimarySupporting
Measure and record original gravity at brew day. · Calculate ABV from OG and FG readings. · Verify final ABV matches style guidelines.
- Source-Owned Initial Infusion TemperatureSupporting
Reconcile one retained source-owned dry-grain initial-infusion temperature model without selecting recipe, process, equipment or safety actions.
- Source-Owned Priming Mass RecordPrimary
Reconcile one retained source-owned package-conditioning mass record without approving product, process, pressure, safety, quality, or release.

Required Packaging EvidenceTable
Owner-controlled records required before source-owned priming-mass arithmetic can be retained.
| Record | Responsible source | Fail-closed hold |
|---|---|---|
| Starting and target CO₂ | Approved batch/packaging plan | Missing, inferred, or style-default value |
| Product coefficient and lot | Exact supplier, laboratory, or approved worksheet | Generic factor or product substitution |
| Package maximum and exposure condition | Manufacturer/rating record plus responsible reviewer | Unknown rating or cold-only assumption |
ABV Calculation FormulaFormula
ABV ≈ (OG − FG) × 131.25. OG and FG measured with hydrometer or refractometer.
Mash Temperature GuideTable
Mash temperature affects body and fermentability.
| Mash Temp | Effect | Best For |
|---|---|---|
| 64–66°C (147–151°F) | Highly fermentable, dry finish | Saison, Belgian |
| 67–69°C (153–156°F) | Balanced body and fermentability | Most ales |
| 70–72°C (158–162°F) | Full body, less fermentable | Stout, Porter, Scotch Ale |
Star San Is Your Best Friend
No-rinse sanitizer (Star San, Iodophor) on everything post-boil. Contact time of 30 seconds is sufficient.
Control Fermentation Temperature
A swamp cooler (water bath + frozen bottles) costs $0 and improves beer quality more than any ingredient upgrade.
Avoid Oxidation After Fermentation
Splashing beer during transfer introduces oxygen and causes cardboard off-flavors. Transfer gently with a siphon.
Start with Extract Kits
Master sanitation and fermentation before all-grain brewing. Extract kits produce excellent beer with less equipment.
Safety Notes
- Never pressurize glass bottles beyond their rating — over-priming causes bottle bombs. Use a priming calculator and measure sugar precisely.
- Propane burners require ventilation — brew outdoors or in well-ventilated areas to prevent carbon monoxide buildup.
