Introduction

This video provides a beginner-friendly guide to making excellent espresso. Lance Hedrick explains the key variables affecting espresso extraction, enabling viewers to understand how adjustments impact taste. The focus is on practical application rather than advanced theory.

Key Takeaways

1. Dose: The ideal coffee dose for your basket should be determined by visual inspection, ensuring a proper puck depth. Overfill, tamp, and remove the portafilter to check for proper headspace (no contact between puck and shower screen). Tools like the Brevel Razor can help achieve optimal depth. Weight-based dosing is acceptable once the ideal puck depth is found.
2. Grind Size: Grind size significantly impacts extraction speed and taste. A coarser grind allows faster water flow, resulting in less dense pucks and potentially faster extraction times. Finer grinds increase resistance and extraction time, which can affect flavor profiles. Adjustments to grind size are usually necessary to achieve desired taste profiles.
3. Ratio: The ratio of coffee to water (e.g., 1:2, 1:1.5) directly influences the concentration and body of the espresso. Lower ratios result in thicker, more concentrated shots, while higher ratios produce weaker, less viscous shots. This variable is easy to adjust for desired strength and body.
4. Time/Pressure/Temperature: While time is less critical than other variables, higher temperatures generally speed extraction. Pressure (typically 9 bars) is largely fixed in most home machines. Optimizing other factors first allows for targeted time adjustments.
5. Troubleshooting: Sour espresso may indicate under-extraction; bitterness suggests over-extraction. Adjustments to grind size, ratio, and extraction time are suggested to address these issues. A systematic approach to adjusting variables is recommended, focusing on the most impactful parameters first.
