Key ideas in Coffee: Flavor and Form
- Crema is composed of trapped CO2 and suspended coffee solids
- A 1:2.5 or 1:3 ratio increases clarity by diluting the heavy oils
- The crema layer is intensely bitter and often stirred in or skimmed
- Lower ratios like 1:1.5 create higher strength but muddy the flavor
- Applying the brew ratio to achieve a specific flavor profile
- 9 bars of pressure emulsify insoluble oils into the liquid
- Pressure forces tactile 'colloids' into the cup for a heavy mouthfeel
- The first drops are the most concentrated and acidic
- Understanding the sensory tradeoff of crema
- Blonding signals that the desirable solids have been depleted
- Recognizing the visual and flavor progression of a shot
- Channeling occurs when water bypasses the puck through cracks
- Identifying the cause of espresso's unique mouthfeel
- A level tamp ensures the water meets uniform resistance
- Stretching introduces air into the milk to create the initial volume
- The 'chirp' sound indicates air is being pulled in to form microfoam
