Key Brewing Parameters / Specs
- Water Temperature: 92°C to 96°C (195°F to 205°F)
- Grind Size: Extremely fine, similar to table salt
- Dose: 18-20 grams for a standard shot
- Extraction Time: 25-30 seconds
- Pressure: 8-9 bars for optimal extraction
Step-by-Step Guide
- Preparation: Grind your beans to an extremely fine consistency. Use a burr grinder for consistent results.
- Tamping: Distribute the ground coffee evenly in the portafilter, then tamp firmly with a tamper to achieve a flat, even surface. Aim for about 30 pounds of pressure.
- Brewing: Lock the portafilter into the machine and start the brewing cycle. Monitor the time and pressure to ensure a consistent extraction.
- Cleaning: Immediately after brewing, steam clean the portafilter to remove any residual coffee oils. This helps prevent buildup and ensures better taste in subsequent shots.
Pro Tips & Common Mistakes
- Tip: Use fresh, high-quality coffee beans. The freshness of the beans significantly impacts the taste and aroma of your espresso.
- Tip: Experiment with different grind sizes to find the perfect balance for your desired extraction. Finer grinds can lead to more crema, while coarser grinds can result in a more robust flavor.
- Mistake: Avoid over-tamping. While firm tamping is essential, applying too much pressure can result in a compacted puck that hinders water flow.
- Mistake: Do not leave the portafilter locked in the machine for extended periods. This can cause heat buildup and affect the taste of your espresso.
