Advanced Cicerone® · Beer Flavor and Evaluation

Aldehydes

Syllabus Path

Advanced candidates should study aldehydes as part of specific beer flavor compounds, connecting the syllabus heading to accurate flavor description, source attribution, and style-fit judgment.

  1. III. Beer Flavor and Evaluation
  2. C. Specific beer flavor compounds
  3. 1. Aldehydes

Exam Focus

  • Explain aldehydes as a sensory evaluation topic within Specific beer flavor compounds.
  • Use specific evidence such as appearance, aroma, taste, mouthfeel, finish, intensity, likely compound, and production or handling context.
  • Apply the topic to accurate flavor description, source attribution, and style-fit judgment rather than repeating the heading alone.

Core knowledge

  • Acetaldehyde is commonly perceived as green apple, raw pumpkin, latex paint, or fresh-cut grass and can indicate young beer, stressed yeast, or oxygen-related staling.
  • Staling aldehydes such as trans-2-nonenal can read as papery or wet cardboard; sherry-like aldehyde notes may be acceptable in some aged strong beers.
  • Evaluate aldehydes by descriptor and context because youthful fermentation character and oxidative age can both sit in this family.

Study application

Name the specific aldehyde impression and decide whether it points to incomplete maturation, oxidation, or acceptable age character.
