Knock's newest hand grinder sets the bar even higher, with a compact offering that doesn't make any sacrifices on performance.

 

Designed to be even more compact and travel-friendly than its big brother, the Feldgrind, the Aergrind still features the same 38 mm coated steel conical burrs and stepless adjustment. Now, however, those burrs sit inside dual bearing mounts in a unibody milled aluminum casing. As before, grind adjustment is stepless and built into the upper portion of the burr shaft. Holding the lid in place, you can change your setting by rotating the handle, with a cutout indicating the number on the lid's dial for reference. In total we find the ideal grind range is covered by the first 5 revolutions of adjustment, with each revolution translating to about 0.7 mm of vertical travel between the burrs. Espresso, drip, and even french press grinds are accessible, however the smaller volume of the hopper and grinds catch make the Aergrind better suited to smaller doses and single cup brews.

The Aergrind is purposefully designed to fit inside the plunger of an Aeropress coffee maker, making for a compact travel coffee setup. The hopper holds about 30 grams of beans, and the grinds catch holds about 25-40 grams at a drip grind (3-4 revolutions). For cleaning, we recommend wiping down parts with a soft, damp cloth and drying thoroughly, and cleaning the burrs using a pipe cleaner or similarly soft-bristled brush.

A Wonderful Manual Grinder at a Reasonable Price!

The quality of the build is exceptional - the shaft rotates easily and appears to be perfectly aligned without any apparent wobble. The parts are finely milled, fit together nicely, and are well designed. The burr spacing is easy to adjust and the handle attaches without much effort and remains in place during the grinding process. The operation of the grinder requires less effort and is considerably more refined than that of the Skerton (non Pro model). The consistency of the grind was comparable to a Baratza Virtuoso. I have not used a Lido, but I am very impressed with the Aergrind. I generally defer purchasing new products until the initial production problems are solved. The product is well packaged in bubble wrap within a cardboard tube. Usually, I can identify flaws or dislikes that I would suggest be corrected in future versions. The only flaw that I have identified is the lack of instructions. However, there are Youtube videos that explain how to adjust the burrs. Finally, there are extra O rings that are included with the grinder.
