What are the parameters of an espresso?

-

To prepare an excellent espresso, it is essential to control several parameters. The most important are:

1. Dose: It is the amount of coffee that we will put in the portafilter. For a double espresso, the most common dose is between 18 and 20 grams, but it will depend on the size of the basket you use.

Grind size: The grind should be fine, with a thickness between 50 and 150 microns. This factor directly influences the extraction time and the flavor of the coffee.

3. Extraction time: According to the SCA, a double espresso should be extracted between 20 and 30 seconds. If it is faster or slower, the flavor can be affected.

4. Water temperature: The water should be between 90 and 96°C.

5. Machine pressure: The ideal pressure is between 8 and 10 bar.

Each of these factors directly influences the taste of your espresso. If you control them well, you will enjoy a rich, balanced and flavorful beverage.
