What We Cover In This Video
There is a lot to unpack when moving from standard airlocks to pressurized setups. In this guide, we break down the differences between professional and homebrewing fermentation, and cover everything you need to get started.
The Benefits
- Warmer Fermentation Temperatures: Pressure suppresses off-flavors, allowing you to ferment at higher temperatures without negative effects.
- Suppressed Fusels and Esters: Results in an exceptionally clean, crisp beer profile.
- Reduced Krausen: Keeps the foam down, effectively increasing your fermenter's usable capacity.
- Trapping Hop Aroma: Volatile hop aromatics are locked into the beer rather than being blown out the airlock.
- CO2 Savings & Pre-Carbonation: Naturally carbonate your beer during the tail end of fermentation.
Equipment Needed
- BlowTie 2 Spunding Valve
- BrewBuilt™ Spunding Valve
- Pressure-rated fermenters (such as the FermZilla Tri-Conical or the BrewBuilt™ Jacketed Uni Conical Fermenter)
- BrewBuilt™ Kit for Fermenting Under Pressure
Safety & Best Practices
- Safety Considerations: Always ensure your fermenter is explicitly rated for pressure and never exceed its maximum PSI limit. Always use a PRV (Pressure Relief Valve).
- Ideal Pressure Ranges: Learn the specific PSI sweet spots for optimizing ales versus lagers.
