As you can see on the right, you have 1 LED on the left side of the machine and 2 LEDs side by side on the right. The first indicator corresponds to an 8 cl cup for a shorter coffee. The other two lights correspond to a 11 cl cup for a longer coffee.
You can choose between 80 and 110 ml! But in any case, the Handcoffee machine will always prepare a single cup of coffee.
