E-61 Group Head for espresso machine

The E-61 Grouphead… Almost sounds scientific…

The E-61 Grouphead is a specific grouphead design found on many commercial machines and some consumer or prosumer espresso machines.

The E-61 grouphead is actively heated by circulating water drawn off the boiler. This aids in the temperature stability of the machine. The group also allows for manual (or automatic) control of preinfusion or passive water access to the Coffee Puck.

The Breville Duo Temp Pro Espresso Machine, is an example of an E-61 Grouphead Prosumer Espresso Machine. It works even better when you’re buying some of the best coffee online!
