Espresso · the pump-pressure myth
The 15-bar myth, debunked with data
Flip any espresso listing and you'll see 15, 19, even 20 bars trumpeted. It is the least useful number on the box — here is why, and what to look at instead.

The physics
Nine bars at the puck is the target
Espresso extraction is defined around roughly 9 bars of pressure at the coffee puck. The 15–20 bar figure on the box is the pump's maximum output — machines regulate it down with an over-pressure valve. A “20 bar” machine makes the same ~9-bar shot as a “15 bar” one.
The consequence
Why a bigger number can be worse
If a machine's regulation is sloppy, excess pump pressure can actually channel and over-extract — bitter shots from a “better” spec. This is why our scoring ignores bar ratings entirely: they carry no information about what reaches the cup.
The better signals
What we score instead
Owner ratings (30%), review volume (35%), and sales rank (35%) — signals from people who actually pulled shots. Combined with documented features like PID control and boiler type, they predict satisfaction far better than any pump claim. Full formula on the methodology page.
