Type 1: Steam-Driven

Water is forced through the espresso grind by steam or steam pressure.  A common broiler has four heads with pipes running to them.  This allowed four different types of espresso to be brewed at one time.  The “Fast Coffee Machine” was steam-driven .   These are also the type of machines that are sold in combination with drip coffee machines.
