Profile the shot, not just pull it.

Up to 14 bar, fully profiled. Flat 9 bar for classics, lever-style decay for sweetness, or draw your own curve. The pump follows it. Every shot, every location.

Roast-matched, and it holds.

PID-controlled temperature. Set 88.0 °C for a dark roast or 96.0 °C for a bright light one, and it stays there. The 49 mm basket is the new standard: sized for the machine, open for your gear. No proprietary nonsense.

03 · Control

Simple on the machine. Everything in the app.

The on-device UI stays deliberately simple: the essentials, readable at a glance. Full control — profiles, temperatures, shot logs, updates — lives in the app. And if you want everything on the machine, the modular port on top takes an optional advanced UI module.

"5am on set. No coffee, or awful instant. I'm a cameraman who happens to think like an engineer, and I couldn't accept that 'portable' had to mean one weak shot and no steam. The easy path was a pod machine with a battery taped on. I didn't want easy. I wanted the machine I wished existed, built in the open."
