Key ideas in Brewing Your Best Cup
- Acids and salts dissolve first in the brewing process
- Sharpness/sourness is a sign of under-extraction
- Sugars and oils follow to provide balance
- Identifying the flavor profile associated with extraction levels
- Heavy, bitter compounds are the last to be extracted
- Increasing contact time allows more sweetness to dissolve
- Adjusting brew time to fix a specific flavor defect
- Acidity is the first stage of extraction
- Bitterness is the final stage of extraction
- The sequence of flavor extraction during a brew
- Boiling water (212°F/100°C) is too hot for coffee extraction
- Heat accelerates the extraction of different flavor compounds
- Excessive heat 'cooks' or burns the delicate oils in the bean
- Lower temperatures fail to extract the sugars and oils that balance acidity
- Over-extraction from high heat leads to harsh, bitter flavors
- Higher temperatures pull out astringent compounds
