BREWING PRESSURE PROFILING CONTROL
The pressure gauge set on the group, allows to read the brewing pressure profiling of the espresso. Thanks to this instruction the barman can verify the exact milling, pressing and dose of the coffee in the filter.
If the brewing pressure is lower than the pump calibration (9 bar is our company setting), it means that the grinding is coarse, or the coffee is not pressed correctly, or the dose is not enough.
