Key ideas in The Art and Science of Espresso Mastery
- Smaller particles pack closer together with less space between them
- Fast-moving water doesn't have enough time to pull out sugars and oils
- Tight packing creates more resistance against the water pressure
- Under-extracted coffee tastes sour, salty, or watery
- How grind size physically regulates water flow
- The flavor consequence of a shot that flows too fast
- A coarse grind offers little resistance, leading to a fast, messy flow
- Slow flow means the grounds are packed too tight
- Pale, watery streams indicate the water is passing through too easily
- Coarsening the grind creates larger gaps for water to pass through
- Visual identification of a grind that is too coarse
- Correcting a shot that is flowing too slowly
- High pressure forces water through the path of least resistance
- Proper resistance allows pressure to build and emulsify coffee oils
- Uneven grounds cause water to 'channel' through gaps instead of brewing evenly
- High pressure is required to create the characteristic foamy texture
