Key ideas in Brewing Your Best Cup
- Darker roasts are less dense and take up more space for the same weight
- Excess water pulls out harsh, bitter compounds from the grounds
- A scoop measures volume, which changes based on bean size and roast level
- Insufficient water fails to wash away the acids, leaving a concentrated sourness
- Under-measuring coffee by weight leads to under-extraction
- Why weight-based measurement is superior to volume-based measurement for consistency
- The sensory outcomes of varying the coffee-to-water ratio
- The ratio is a fixed relationship that scales linearly
- Consistency relies on the math of the ratio rather than 'eyeballing' the amounts
- Boiling water extracts compounds too quickly
- Low temperature water fails to extract the sweet and heavy oils
- Over-extraction from high heat results in harsh bitterness
- Under-extracted coffee tastes sour and lacks body
- The ideal brewing range is slightly below boiling
- Extreme heat and extreme cold produce distinct flavor defects
- The relationship between high water temperature and flavor extraction
