Advanced Cicerone® · Beer Ingredients and Brewing Processes

Yeast

Syllabus Path

Advanced candidates should study yeast as part of ingredients, connecting the syllabus heading to wort composition, fermentation performance, flavor, stability, clarity, carbonation, and mouthfeel.

  1. IV. Beer Ingredients and Brewing Processes
  2. A. Ingredients
  3. 3. Yeast

Exam Focus

  • Explain yeast as a brewing analysis topic within Ingredients.
  • Use specific evidence such as raw material form, time, temperature, pH, oxygen, gravity, microbes, vessel, pressure, and sanitation.
  • Apply the topic to wort composition, fermentation performance, flavor, stability, clarity, carbonation, and mouthfeel rather than repeating the heading alone.

Core knowledge

  • Yeast choice affects attenuation, flocculation, alcohol tolerance, ester production, phenols, sulfur, diacetyl, and fermentation speed.
  • Pitch rate, oxygen, nutrients, temperature, pressure, and wort composition change yeast performance.
  • Ale, lager, Brettanomyces, bacteria, and mixed cultures require different expectations for flavor and process control.

Study application

Trace fermentation character and attenuation back to strain selection and yeast management.
