MANUAL
The barista manually controls pre-infusion and pressure during the shot.
The barista starts and stops the shot to achieve the preferred coffee volume.
EE
SEMI-AUTOMATIC
The Barista starts and stops the shot with either a push button or paddle interface to achieve the preferred coffee volume.
AV
AUTO-VOLUMETRIC
The barista starts the shot and the machine stops it, based on the pre-programmed volume of water running through the coffee to achieve the preferred coffee volume.
ABR
AUTO WITH SCALE
The barista starts the shot and the machine stops it, bases on the weight of the coffee in the cup. Auto Brew Ratio utilizes a built-in scale to achieve the preferred coffee weight.
Straight-in portafilter
Designed to simplify the motions required to engage the portafilter and reduce strain by 12x on the
barista for even greater performance and everyday usability. High-volume coffee environments
demand that a barista can work quickly and efficiently to produce drinks during the busiest periods
of the day. The Straight-In Portafilter can noticeably mitigate repetitive stress injuries through its
ease of action, improving the natural workflow and output of the barista.
Auto steam flush
After each extraction, a burst of steam from the steam boiler purges the brew path and is followed
by a flush of hot water, keeping the group clean even during the busiest hours. This innovative
function minimizes coffee residue in the group, and reduces the number of times baristas need to
back flush during service.
Drip prediction algorithm
Precision scales incorporated into the drip tray improve beverage consistency by stopping the
extraction based on mass. The machine uses an algorithm called Drip Prediction to improve shot
accuracy and ease of dialing in.
