How we test coffee grinders

How we put coffee grinders to the test to help you buy the best.

The grind on coffee grinders

If you can't start the day without your coffee and have invested in a fancy espresso machine for all your coffee needs at home, you should probably consider adding a coffee grinder to the family. Grinding your beans right before you make your coffee is the best way to extract their full flavour.

Our expert tester is passionate about his coffee and knows how important it is to have the right coffee grinder. He knows how to put them to the test to help you choose what to buy.  

Our expert testers

Our expert tester is the master of testing general appliances. While he is passionate about getting the perfect coffee, his expertise lies not only with coffee machines, grinders and roasters; he regularly assesses vacuum cleaners as well as toasters, kettles and steam mops. But that's not all – his pet projects involve getting out of the CHOICE laboratory and heading out to the race track to test car tyres or heading to the Hunter Valley to test tents, lawn mowers and all sorts of other goodies.

How we choose what we test

With a range of products on the market, what makes us choose one coffee grinder to test over another? As with most of our product testing, our aim is to test the most popular models on the market and what you are most likely to see in the retailers.

We survey manufacturers about their range of models, check market sales information and also look for any member requests to test specific models. From this information we put together a final list that goes to our buyers. They then head out to the retailers and purchase each product, just as a normal consumer would. We do this so we can be sure they are the same as any consumer would find them and not 'tweaked' for testing in any way.

How we test

Our tester, Peter Horvath, puts coffee grinders to the test by assessing their performance and ease of use.


Peter measures the fineness of grind by adjusting each machine to produce a grind suitable for our semi-automatic ECM Giotto machine. He makes two cups of espresso and judges the crema quality and the strength of the coffee.

Ease of use

Peter assess how easy it is to:

  • Set the timer
  • Adjust the controls
  • Remove coffee from the grinder
  • Clean the machine
