Grain Milling
We automatically mill the grains included with SoCal Brewing Supply beer recipe kits so they are ready for brew day. If you want the grains left unmilled, please add that request in the shopping cart notes before checkout. We’ll do our best to support unmilled requests when packing your order.
Fermentation Requirements
Recommended fermentation temperature: 64–70°F. Steady ale fermentation temperature helps prevent hot, solvent-like, or overly fruity off-flavors.

Why Brewers Choose the Partial-Mash Version

Brewing Notes
- Read the instructions first: Separate ingredients by timing before heating water.
- Control fermentation temperature: Stable fermentation improves clarity, flavor, and repeatability.
- Protect finished beer from oxygen: Careful transfers and packaging help preserve malt and hop character.
- Plan carbonation separately if bottling: Priming sugar is sold separately.
If you are bottle conditioning, purchase Powdered Dextrose Priming Sugar separately and use our Priming Sugar Calculator.
If kegging, use our Keg Carbonation Calculator to dial in serving pressure and carbonation level.
Helpful Bottling & Kegging Add-Ons
- Bottling this batch? Add powdered dextrose priming sugar so you are ready on packaging day.
- Use our Priming Sugar Calculator to dial in the right amount of sugar for your beer volume, temperature, and carbonation target.
- Kegging instead? Use our Beer Carbonation Chart & Keg Serving Pressure Calculator to choose the right CO₂ pressure for your serving temperature and carbonation level.
