How to make the best espresso

Brewing the perfect espresso is an art that combines passion, precision and knowledge. Every step in the process influences the final result, from the selection of beans to the extraction technique. Below, we offer a detailed guide so you can enjoy an exceptional espresso in the comfort of your own home.

1. Selection of high quality grains

The first step towards a perfect espresso is choosing high-quality coffee beans. Arabica beans are renowned for their smooth and aromatic flavour. It is advisable to purchase fresh, single-origin beans, as this ensures a more authentic and distinctive flavour experience.

2. Precise grinding

Coffee grinding is crucial for proper flavor extraction. For espresso, a fine and uniform grind is required. A burr grinder is ideal for achieving this consistency, as it allows you to adjust the grind level according to your preference and the freshness of the beans.

3. Exact dosage

The amount of coffee used directly influences the intensity and balance of the espresso. For a standard dose, it is recommended to use between 7 and 9 grams of ground coffee per 30 ml of water. However, many baristas opt for more generous doses, between 18 and 20 grams, for a richer and more complex extraction.

4. Uniform pressing

The tamping of the coffee into the portafilter must be uniform and with the right pressure. This ensures a homogeneous resistance to the passage of water, resulting in a balanced extraction. Inconsistent tamping can cause channels where the water flows more quickly, affecting the taste of the espresso.

5. Temperature and pressure control

Water temperature and pressure during extraction are determining factors in the quality of espresso. The ideal water temperature ranges between 90 and 96 degrees Celsius, and the pressure should be at least 9 bars. These parameters ensure optimal extraction of the coffee's aromatic compounds and flavours.

6. Extraction time

The ideal extraction time for an espresso is about 25 to 30 seconds. A shorter time can result in an under-extracted and acidic drink, while a longer extraction can produce bitter and unpleasant flavors.

7. Equipment maintenance

Clean equipment is essential for preparing a good espresso. Coffee residue and oils can build up on the machine and grinder, affecting the taste of future preparations. It is essential to regularly clean all components and perform periodic maintenance according to the manufacturer's recommendations.

8. Practice and experimentation

Preparing the perfect espresso takes practice and a willingness to experiment. Adjust variables like grind, dosage, and brewing time until you find the balance that suits you best. Every coffee is unique, and discovering its nuances is part of the experience.

By following these steps and paying attention to every detail, you will be able to enjoy an exceptional quality espresso in the comfort of your home. Your dedication and love for coffee will be reflected in every cup you prepare.
