Pressure and Flow Control¶

Summary:: In espresso, pressure and flow rate shape how water moves through the coffee bed and how quickly compounds extract.

Typical pressure: Many setups target around 8–10 bar at the puck, depending on recipe and machine.
Flow ideas:
Higher flow can shorten contact time and risk under-extraction.
Lower flow can extend contact time and risk over-extraction if grind is not adjusted.
Advanced practice: Pressure or flow profiling modulates these over the shot to influence flavor balance.
