Uncompromising quality.

The new and improved 2022 Aergrind is a beautifully built grinder from Knock, hand built here in Edinburgh, Scotland. We are proud to partner with Knock, and we think they build some of the worlds best hand grinders.

The new Aergrind has been upgraded to be stronger and more redefined than its predecessor. 38mm titanium nitrided conical burrs provide competition level grind consistency. The axle bearing length has been increased to provide even greater stability and improved alignment. The refreshed profile of the crank arm is now 20% thicker too.

The design refinements continue with a move away from plastic to a larger, walnut wood knob; a snap-on magnetic lid with laser etched precision aluminium dial; and a custom threaded "screw on" lower tube, profiled to provide a controlled pour for your precious coffee grounds.

Unlike other manual grinders where the grind adjustment is on the burrs, the Aergrind has a dial at the top of the grinder. This makes changing the grind easier and cleaner. The dial’s settings are read via a combination of two factors, the number of full rotations and the reading on the dial itself.
