7. Taste and adjust: Once the extraction is complete, taste the espresso. It should have a balanced flavor, rich body, and a pleasant crema. If necessary, make adjustments to the grind size, coffee dose, or extraction time to achieve your preferred taste.
8. Clean and maintain: After use, clean the portafilter and the machine to prevent any coffee residue buildup. Regularly backflush the espresso machine and follow the manufacturer's instructions for cleaning and maintenance.
Note: Mastering espresso brewing can take practice. Factors like grind size, coffee dose, water temperature, and extraction time can greatly impact the flavor. Experiment with different beans, ratios, and techniques to perfect your espresso brewing skills.
