Exam Focus
- Explain other compounds 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
- DMS reads as cooked corn, creamed corn, tomato juice, or cabbage and is linked to malt precursor, boil vigor, covered hot wort, and slow chilling.
- Lightstruck character is skunky and forms when light reacts with hop compounds; brown glass protects better than green or clear glass, while cans block light.
- Metallic character may come from water, equipment, package contact, or oxidation and should be separated from bloodlike, coinlike, or inky impressions.
Study application
Connect each non-core compound to its handling or process pathway and the practical prevention point.
