Brewing Tips
- Gravity Readings: Always take hydrometer readings at the calibrated temperature (usually 60°F/15.5°C) for accurate ABV calculations
- Hop Utilization: IBU calculations depend on boil time, gravity, and alpha acid percentage; higher gravity worts extract fewer IBUs
- Mash Temperature: Target 148-156°F (64-69°C) for most styles: lower for drier beers, higher for fuller body
- Yeast Health: Proper pitch rates prevent off-flavors and stuck fermentations; lagers need roughly twice the yeast of ales
