Exam Focus
- Explain carbonation as a brewing analysis topic within Processes.
- Relate dissolved CO2 to temperature, pressure, beer composition, nucleation, package method, and dispense presentation.
- Compare natural conditioning, spunding, forced carbonation, and mixed-gas approaches for texture, aroma release, foam, timing, and stability.
Core knowledge
- Carbonation can be captured during fermentation, forced with CO2, or created by secondary fermentation in bottle, can, keg, or cask.
- Carbonation affects aroma lift, foam, perceived acidity, texture, fullness, dryness, and how beer interacts with food.
- Temperature, pressure, time, residual fermentables, yeast health, and package strength all matter to carbonation control.
Study application
Connect carbonation method to sensory texture and package or service risk.
