Exam Focus
- Explain phenols 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
- 4-vinyl guaiacol gives clove or spice and is expected in many weissbier and some Belgian profiles.
- Chlorophenols can taste medicinal, plasticlike, adhesive-bandage-like, or smoky and often point to chlorine or chloramine contact.
- Phenolic character can come from POF+ yeast, wild microbes, smoked malt, spices, or water-treatment problems.
Study application
Use descriptor and style context to separate intentional yeast phenol from sanitation or water-related faults.
