Aroma-3 · macroHow it works
A grinder that spins on a real bearing.
We ditched metal-on-metal contact for a precision SKF 608-2RSL bearing. Every turn is smooth and effortless, and the lid lifts straight off. It's built to go the distance.
It's also a standard skateboard-size bearing, so it's yours to customise. The Bearing Press swaps it in minutes, and popping it out before you wash the lid makes cleaning quick and easy.
Play with it
Take it apart.
The real Aroma-3 from our CAD, riding a sealed SKF 608 bearing. Flick the lid to spin it, lift the lid or middle off, or explode it to see every part, bearing included. It only spins once it's back together.

Bench Run.
An Aroma lid has escaped across the workbench. Tap, click or press Space to jump; hold for a bigger jump and tap again mid-air for a double. Clear the clutter, grab the herb, and see how far it rolls.

How Bench Run scores
- Every metre is a point. The lid speeds up for the first minute, then stays flat out.
- Herb is +5. It floats over the clutter, so you have to jump for it.
- Hold for height, tap twice to double jump. The tall jar stacks need one or the other.
- One hit and it's over. Lighters, papers, jars and gaps in the bench all count.

The material
Italian steel. South Australian machining.
We machine every grinder from Maxival® 304L, a free-machining stainless made by Acciaierie Valbruna in Italy. It's the same grade trusted in medical, food and aerospace work.
It means cleaner cuts, sharper teeth and a food-safe finish that won't pit, crack or flake. There's no anodising and no ceramic coating, just solid steel.
Why we do it
Obsessed with doing things properly.
I've spent the last 12 years in high-end manufacturing across aerospace, defence and automotive. Designing, prototyping, solving problems and overcoming challenges is the part that lights me up. That's why Old Mate Designs exists.
Every grinder is designed, prototyped, machined, assembled and shipped by the same small team, and the designs keep improving based on your feedback.

★★★★★“After a year of daily use, the only thing I regret is that I didn't get the spoon. I haven't even changed the original bearing.”

Every grinder is made to order. Orders are processed within 1–3 weeks, and you'll get tracking as soon as it ships. Pre-orders ship on the date shown on the product.
How do I open my Aroma?
Lift the lid straight up and off. Twisting, rocking or the clamshell technique will make it harder. On the Aroma-3, pivot the bottom plate open like a clamshell or lift it straight up.
