An espresso machine, drawn from the water up.
Flow you can dial, not just pressure. A 316L stainless group, neutral in the cup. Brew temperature held steady, shot to shot. Every part chosen and documented - not styled.

Reservoir, pump, flow-through heater, 316L group, cup - a pure espresso machine, with no steam circuit competing for heat or space. The first prototype ran a rotary vane pump; the production path moves to a gear pump. We care about the same things you do: even extraction, a smooth pre-infusion, and shots that taste the same every morning. A gear pump gets us there - it meters water by the turn, so flow is something you set, not something you hope for.
- aFlow tracks speed - positive displacement, output proportional to shaft speed.
- bProfile-ready - flow-by-wire, so you can shape pressure and flow through the shot.
- cLow pulsation - smooth pre-infusion and a stable extraction.
- dCompact and quiet - a small unit that disappears into the body.

Heat on demand, held steady shot to shot.
A flow-through heater brings water to brew temperature in seconds - little mass to preheat, no waiting around. Closed-loop control holds that temperature across the whole shot, not just at the start, so every cup pulls the same. The group head is solid 316L stainless and takes a standard 58 mm basket - inert, easy to keep clean, and ready for the accessories you already own.
