What is Pump Pressure?
Pump pressure indicates the maximum force the machine's pump can exert to push hot water through the compacted coffee grounds. While pumps often state 15 bars, optimal brewing pressure at the group head is typically around 9 bars, with machines regulating this internally.
Why does pump pressure matter?
Sufficient pressure is crucial for extracting the full flavor and crema from espresso. Too little pressure results in under-extraction; too much can lead to over-extraction.
What is a good pump pressure value?
Around 9-15 bars indicated on the pump, with actual brewing pressure around 9 bars being ideal for espresso extraction.
How is pump pressure measured?
