How much ground coffee should I use to make an espresso?

The quantity of ground coffee required to obtain a single-shot or a double-shot espresso may vary, based on your personal taste, on the grind size, and on the type of coffee used. As reference, you should use 10-12 grams for a single-shot espresso, and 18-20 grams for a double-shot espresso. If you use the E.S.E. pods, the coffee quality will be more consistent.
