Mueller HyperGrind Precision Review

While the HyperGrind Precision generally functions like most other blade grinders on the market, some extra annoyances with its cleanliness and ease of use dropped it to the bottom of our scoresheets.

Likes

The most pleasing thing (or, more accurately, the least displeasing) thing about the HyperGrind Precision is the noise that it emits. One generally expects a blade grinder to sound a bit like a plane propellor crashing through a jungle canopy, but the HyperGrind manages to keep its noise relatively innocuous and at a fairly low-medium pitch. Still, it does create quite a cacophony for a few seconds before the beans break down a bit.

Apart from not sounding as grating as some other blade models, our only accolade for the HyperGrind is its price. It is a lot cheaper than all of the burr models we tested and is on the lower end of the price spectrum when it comes to blade grinders as well.

Dislikes

Unfortunately, our list of dislikes for this machine is longer than our list of likes. First off, like all of the blade grinders on the market, the HyperGrind fails to create a consistent grind size. This is because the blades randomly slice through the pile of beans with no way to control the actual size of the particles it produces. This results in a different amount of large and small grinds every time you make coffee and is likely going to result in a different taste and sub-optimal extraction every time. This is the big sacrifice you make with a blade grinder, with the only other option being spending magnitudes more on a burr grinder.

Our biggest gripe with the HyperGrindis the mess that it makes when you use it. This comes from the large amount of fine coffee dust that is produced, which sticks all over the grind cup and generally must be cleaned off with a brush or rag. That stuck coffee also makes pouring the grinds into your coffee maker less than predictable, as sometimes the grinds pour slowly and smoothly, and sometimes you get a sudden coffee avalanche. This resulted in us dumping a good amount of grinds onto the counter while using this machine.

The problem of small grinds gunking up the machine is made worse by the fact that you cannot remove the cup with the actual blades in it. This makes it nearly impossible to get the blades fully clean, as you can't run them under a faucet or put them in the dishwasher.

Value

The HyperGrind Precision is quite inexpensive. However, we've found similarly inexpensive blade grinders that we've liked slightly better. In general, we've found the differences between blade grinders to be small, but if we're splitting hairs, we would say there are better values to be found in other blade grinders.
