Kinetic Concentric hand grinder on a kitchen bench
Hand-built espresso machinery

Machines made to last.

No motor, no screen, nothing to update. Espresso equipment designed and built by one person who wanted it to exist — then made it properly.

Fifteen seconds of your morning. A lifetime of the machine.

Grinding 20 g for espresso by hand takes about fifteen seconds on the Concentric. In exchange you get silence, no electronics to fail, and a grinder that will still be working when the appliances around it have been replaced twice.

What I build to
01

Materials you don’t apologise for

316 stainless steel, 6061 aluminium anodised and bead-blasted, hardwood. Nothing chromed, nothing coated to hide what it is. The bean path is plastic-free.

02

Mechanical, not electronic

Gears, shafts and a flywheel do the work. Stepless adjustment marked to 0.001 mm. There is no firmware, no app and no Wi-Fi to fall over.

03

Serviceable at your kitchen table

Every part is visible and reachable with ordinary tools. If something wears in twenty years, you replace that part — not the machine.

Stainless steel flywheel
820 g stainless flywheelGeared at 6.5× crank speed — 42 times the stored energy of a direct-mounted wheel, in a 60 mm package.
Drive gears and 83 mm conical burrs
83 mm conical burrsInner and outer burr on a single carrier, so they stay square and concentric under load and temperature.
Machined stainless and aluminium components
Stepless to 0.001 mmThe dial turns with the shaft, so there is no float in the adjustment and the marks always face you when you stop.

Who’s behind it

I design the machines I wanted to own.

I spent eight years building mechanical products in a different industry — gears, cams and levers. Kinetic is the same way of thinking pointed at coffee: what a machine built a hundred years ago would look like if it were designed today, with today’s materials and tolerances.

None of it is cheap. All of it is meant to outlive me.
