Step-by-step espresso preparation
1. Coffee grinding
Grind 10 grams of coffee until you obtain a fine texture, similar to powdered sugar. Fresh grinding is essential to preserve the aromas and flavors.
2. Dosage and compaction
Use the scale to measure exactly 10 grams of ground coffee. Pour the coffee into the portafilter and distribute it evenly. With the tamper, compact the coffee by applying firm, constant pressure to ensure even extraction.
3. Machine preparation
Before inserting the portafilter, purge the machine by running hot water through it for a few seconds. This stabilizes the temperature and removes any residue. Insert the portafilter immediately after tamping the coffee to maintain freshness.
4. Placing the cups
Place two 70cc espresso cups under the machine's nozzles. Make sure they are centered to collect the espresso evenly.
5. Espresso Extraction
Start the extraction by pressing the corresponding button. The extraction time should be between 25 and 35 seconds. You should obtain between 40 and 50 grams of espresso in total. Observe the crema that forms on the surface; it should be hazelnut-colored, thick, and uniform.
6. Evaluation and enjoyment
Taste the freshly brewed espresso. The texture should be velvety and the aroma intense. Enjoy the experience you've created.
Tips for adjusting the extraction
- Rapid extraction (less than 25 seconds)Use a finer grind or increase the pressure when compacting.
- Slow extraction (more than 35 seconds): Opt for a coarser grind or reduce the pressure when compacting.
- Water qualityUse filtered water to avoid unwanted tastes and protect your machine.
