The Disadvantages of the Knock Aergrind

Knock Aergrind Features

The main disadvantage of the Knock Aergrind coffee grinder is that it can be hard to find. It’s not available on Amazon, and many retailers sell out quickly due to the popularity of the product. The supply problem is also due to the fact that the product is made in Scotland, and only a small number reach the American market. Made by Knock is also a small company.

Another disadvantage is that it has a small dial lid which could easily get lost. Some customers have also complained that it produces too finer grounds for a V60.

Some people find that it’s difficult to pour coffee beans into the grinder as it’s so narrow. However, this job becomes much easier if you use a funnel. A funnel comes with the Aeropress coffee machine, which can be used with the Aergrind and perfectly fits the grinder.

Another disadvantage is that the Aergrind doesn’t come with any instructions and doesn’t have a manual with it. You’ll therefore have to work out how to use it yourself or can find instructions on the website or forum.

Grind Consistency

Whichever setting you choose, the Aergrind consistently produces the grind you want, it uses a drop-down method, so when the grinds are the right coarseness, they will drop into a compartment at the bottom of the grinder. This means that you won’t find coarse grains in your finely ground coffee.


The Aergrind is an excellent coffee grinder for coffee lovers and those who enjoy artisan coffees. This grinder will give you the option of creating coffee grinds precisely how you want them, either very coarse or very fine. It has an easy to set dial and consistently produces the correct coffee grinds.

If you usually brew one or two cups of coffee at a time, the Aergrind is great for you. If you want to brew more cups at once, you may need a larger grinder. The Aergrind is a compact grinder that is of excellent quality.

The Aergrind works well for most manual brewing methods, such as the French Press method. It is, however, best used in conjunction with the Aeropress. The Aergrind is very well made and is portable, and great for traveling.
