Key ideas in Brewing the Perfect Cup
- A scoop measures volume, which changes based on bean size and roast level
- 1:15 to 1:17 is the standard range for a balanced cup
- Darker roasts are less dense and take up more space for the same weight
- Lower ratios (less water) result in a stronger, more intense brew
- Weight vs Volume in Roasts
- Brew Ratios and Strength
- Decreasing the water-to-coffee ratio increases the strength
- The relationship between specific brew ratios and the resulting strength of the cup
- Using a scale allows for precise, repeatable adjustments
- The logical workflow for adjusting a weak cup of coffee using a scale
- Sourness is a sign of under-extraction
- Smaller particles (fine) expose more surface area to water
- Bitterness is a sign of over-extraction
- Fast extraction leads to over-extraction if not timed correctly
- Identifying the taste profile of over-extraction versus under-extraction
- Mapping grind size to its effect on extraction speed and flavor
