Who are Knock?
Knock are a grinder company based in Edinburgh, which makes their products extra special to us. They make extremely good grinders, that we have sold for some time now. We class them right up there with the Comandante's of this world.
What is the Aergrind?
The Aergrind has proved itself to be one of the best professional hand grinders in the world. Now in its 4th variation, it's as solid and slick as ever, with what we see as the ultimate in refinement of an already amazing product.
It's Knock's smallest, portable grinder that is probably their most popular product to date. It's compact, high quality, easy to use and fits inside an Aeropress. It grinds to a very uniform consistency with a range from espresso to filter and lots in between. It is stepless, meaning it adjusts very smoothly, and not limited to pre-defined grind settings.
What's new about the 2022 Aergrind?
- It has a beautiful wooden knob on the handle that fits with a magnetised click.
- The bottom is new a screw fit, which removes any potential for slippage of the top and bottom sections.
- The top section that shows the dial is much higher quality, with nicely embossed figures and markings. It is also magnetised to fit snugly with ease.
- The beer bottle opener is still there!
What Knock say about the new 2022 version:
5 years on from the release of our class-leading compact coffee grinder, we're introducing a new and improved Aergrind for 2022. 100% plastic free and hand built in Scotland, the new Aergrind has been upgraded to be stronger, longer lasting and more refined that its predecessor.
Key technical upgrades begin where it matters - 38mm titanium nitrided conical burrs for competition level grind consistency and a step up in burr class. Inside the grinder, we've increased the axle bearing length by 100% to provide even greater stability and improved alignment. The refreshed profile of the crank arm is now 20% thicker at 3mm.
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.
But most importantly some things have not changed - the Aergrind is still designed to partner perfectly with the Aeropress, packing into the body of the brewer, with a crank arm and band that fit compactly around the body for the ultimate portable brew kits.
Italmill still powers the grind and it remains a supremely capable Turkish and espresso tool thanks to the unique profile of these time-proven classic burrs.
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 easy and clean as your fingers don’t get covered in coffee.
Instead of using pre-set clicks, the grind adjustment is stepless which means that you have unlimited options on where to set your grind, giving you the best chance to maximise the flavour of your coffee.
Knock grinders come with a standard 1 year back to base warranty with Machina. *See our terms and conditions for further information
