Brew parameters

Pressure

Also known as pressure · bar · presión de extracción · brew pressure

Máquina de espresso: presión de extracción

What it is and what sets it apart: Pressure ≠ flow rate though coupled. Gravity filter has negligible pressure; espresso/moka central. Distinct from tamping force.

How it’s used or measured: Check gauge or profile (flat 9 bar or ramp). Log flat vs variable in Brew Lab.

Flavours and cup impact: Right pressure + good puck: balanced body/crema. Excess with channels: spray; too low: under-extraction.

Technical notes: Pump pressure ≠ basket pressure if channeling. Preinfusion uses low pressure on purpose.

Common mistakes: Raising bars for “more crema”. Confusing tamp force with brew pressure.
