A Bialetti percolator is a typical Italian coffee machine. With such an espresso pot, you can make a strong cup of coffee. To make coffee with a percolator, fill it with ground coffee and cold water. Afterwards, put the Italian coffee pot on a cooktop in its entirety. Just wait until you hear it hiss and your coffee is ready. The number of espressos that you can make depends on the size of the percolator.
