Commercial Espresso Machines

Espresso machines feature single or dual wands that force the hot water over the grounds. The water has to be at the right temperature, just below boiling point. To make espresso, the barista grinds a small amount of beans (about one tablespoon’s worth) into a mesh basket. After packing the grounds, the basket is placed under the wand on the machine. The hot water is then forced through the grounds using either a mechanical or automatic pump. The hot water strips the flavors and essential oils out of the grounds and into the liquid shot. The brewing process should take around 30 seconds.
