Beginner Tips
- •Most ales sit at 2.2 to 2.6 volumes; lagers a touch higher.
- •Colder beer holds CO2 more easily at lower pressure.
- •Give force carbonation several days at set pressure for stability.
Common Mistakes
- •Setting pressure by guesswork instead of temperature.
- •Serving too warm, causing foamy pours.
- •Over-carbonating British styles that should feel soft.
