Key ideas in Brewing Your Best Cup
- Strength refers to the ratio of coffee solids to water (intensity)
- Over-extraction refers to pulling out undesirable organic compounds (bitterness/dryness)
- A cup can be both strong and over-extracted simultaneously
- Over-extraction causes a physical sensation of astringency or dryness
- Bitterness and dryness are the primary indicators of excessive contact time
- Acidity and fats extract first
- Sugars and sweetness extract in the middle
- Bitter, heavy plant fibers extract last
- The relationship between contact time and flavor development
- Identifying the sensory hallmark of over-extraction
- Boiling water (212°F/100°C) is too hot for most coffee and can 'scorch' the grounds
- Sourness is a sign of under-extraction
- Excessive heat extracts bitter, ashy compounds that mask delicate notes
- Higher temperatures accelerate extraction to pull out sweeter, more balanced flavors
- The impact of boiling water on coffee flavor profile
- Using temperature as a tool to fix sourness
