Key ideas in Precision Coffee: Dialing and Roasting
- TDS vs Extraction Yield
- Salami Shot sequence
- Brew ratio and yield
- The pump provides constant pressure, but the flow rate is determined by the permeability of the compressed coffee bed.
- High initial heat facilitates the extraction of delicate, high-volatility floral compounds.
- Distinguishing between beverage strength and the efficiency of the extraction process
- Fines migration and puck degradation during the shot cause the resistance to change dynamically.
- Lowering temperature during the tail end of the shot reduces the extraction of heavy, bitter compounds that dissolve more easily in hot water.
- Identifying the chronological transition of flavor compounds during an espresso extraction
- Grind size and distribution are the primary tools for 'shaping' the flow curve.
- Thermal energy is a selective solvent for different molecular weights in coffee.
- Applying temperature profiling to manipulate specific flavor extractions
- Understanding that the coffee puck, not the machine, is the primary regulator of flow
- Magnesium ions are highly 'sticky' and pull out larger, more complex flavor molecules.
- The coffee puck, not the machine, is the primary regulator of flow
- Calcium is effective at extracting heavier compounds that contribute to body but can be less selective than magnesium.
