It is a coffee of minimum 110ml. It is often drunk in the morning in coffee mugs or bowls, possibly with milk. It is prepared with a drip coffee maker, a coffee pot or even an electric kettle. The infusion is slow. Europe, Germany, the Netherlands and the Nordic countries are fond of this type of coffee. They drink loads, particularly the Swedes.
It is an approx. 80ml coffee prepared at a 2-bar pressure with coffee machines or a piston coffee maker. This is a coffee very widespread in France.
To prepare an espresso coffee, you need a fine grind and an espresso machine able to build 16 bar pressure! The espresso is served in small cups of about 40 ml. It is an Italian coffee. In Naples, they go for an even shorter espresso called "ristretto". No more than 20-25 ml prepared with an espresso machine or their famous bialetti coffee maker. Enough really to boost you!
Whether long or short, a good coffee is always a freshly brewed coffee drunk straight away. The thermo-insulated coffee percolator is over! What’s in now is to drink quality coffee at home as if you were in a good café.
