The compact Caffè dell’Opera has a built-in coffee mill with conical grinders adjusted to the fraction of a millimetre.
The large boiler is in brass, in the old tradition of professional coffee-makers, to guarantee a thermal inertia allowing excellent control of the temperature, governed by thermostats operating with a tolerance of less than 5 °C.
Both machines are equipped with solenoid valve on the water delivery unit. This device cuts out water drips from the filter or spout at times when the pressure is high.
The solid professional brass filter-holder retains the heat, always guaranteeing an espresso at the ideal temperature. All internal pipes are in brass. The specially designed steam spout is equipped with a device for easy frothing of milk when making a cappuccino.
