WHAT IS A VOLUMETRIC ESPRESSO MACHINE?
Volumetric espresso machines are also known as "automatic" are the most popular type of commercial espresso machine. The machine uses an internal timer to cut off the shot after a certain amount of time - usually 25-30 seconds. Additionally, automatic espresso machines have automatic pumps and volume. Programmable buttons are used to preset the volume so the user can press a single button to pull an espresso shot. These machines are recommended for any installation looking for consistency among users.
Volumetric espresso machines are consistent, reliable, and allow the barista to perform other tasks while the shot is extracted. It also requires a less experienced barista, reducing training/employee costs.
