Advanced Cicerone® · Beer Ingredients and Brewing Processes

Fermentation

Syllabus Path

Fermentation converts sugars into ethanol, CO2, heat, and flavor-active compounds including esters, phenols, sulfur compounds, diacetyl, and organic acids. Trace finished-beer flavor and attenuation back to fermentation management.

  1. IV. Beer Ingredients and Brewing Processes
  2. B. Processes
  3. 8. Fermentation

Exam Focus

  • Explain fermentation as a brewing analysis topic within Processes.
  • Track gravity, temperature, pH, yeast growth, attenuation, flavor formation, pressure, and maturation through the fermentation curve.
  • Design controls that produce the intended ester, phenol, sulfur, alcohol, and finish profile while identifying evidence of stress or contamination.

Core knowledge

  • Fermentation converts sugars into ethanol, CO2, heat, and flavor-active compounds including esters, phenols, sulfur compounds, diacetyl, and organic acids.
  • Yeast strain, pitching rate, oxygen, nutrients, wort composition, temperature, pressure, and sanitation shape attenuation and flavor.
  • Warmer or stressed fermentation can increase esters, fusel alcohols, sulfur, diacetyl, or incomplete attenuation depending on strain and conditions.

Study application

Trace finished-beer flavor and attenuation back to fermentation management.

Key Terms

Warmer or stressed fermentation
Warmer or stressed fermentation can increase esters, fusel alcohols, sulfur, diacetyl, or incomplete attenuation depending on strain and conditions.
