What are the parameters of an espresso?

-

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

1. Dosis: Es la cantidad de café que pondremos en el portafiltro. Para un espresso doble, la dosis más común está entre 18 y 20 gramos, pero dependerá del tamaño de la cesta que uses.

2. Tamaño de molienda: La molienda debe ser fina, con un grosor entre 50 y 150 micrones. Este factor influye directamente en el tiempo de extracción y el sabor del café.

3. Tiempo de extracción: según la SCA un espresso doble debe extraerse entre 20 y 30 segundos. Si es más rápido o más lento, el sabor puede verse afectado.

4. Temperatura del agua: El agua debe estar entre 90 y 96°C. 

5. Presión de la máquina: La presión ideal está entre 8 y 10 bares. 

Cada uno de estos factores influye directamente en el sabor de tu espresso. Si los controlas bien, disfrutarás de una bebida rica, balanceada y llena de sabor.
