Key ideas in The Art of the Espresso Shot
- The 1:2 ratio is a starting baseline to be adjusted based on taste
- Coarser particles create larger gaps for water to pass through quickly
- Increasing the yield (e.g., 1:2.5) can mellow out harsh, intense flavors
- Finer grinds increase resistance and slow down the water flow
- Darker roasts often benefit from shorter ratios to avoid over-extraction
- Grind size is the primary variable used to hit a target 25-30 second shot
- Applying the 1:2 ratio as a flexible starting point for different roast profiles
- Predicting flow rate based on grind size adjustments
- Crema is mostly trapped CO2 and varies significantly between bean ages
- Measuring by weight ensures the actual dissolved coffee solids are consistent
- A 30ml shot of fresh coffee has less liquid than a 30ml shot of old coffee
- Acids and oils extract first, followed by sugars, then bitter plant fibers
- The Salami Shot involves swapping cups every few seconds during the pull
- Tasting shot phases separately teaches you when to stop the flow for balance
- Overfilling a basket leaves no 'headspace' for the shower screen to distribute water
- Understanding why weight is superior to volume for measuring espresso
