Best Coffee Grinder of 2024 – CNET [CNET]

View Article on CNET

It doesn’t matter if you have the most expensive coffee maker on the market, if you’re still brewing with mediocre grounds then you’ll always have a subpar cuppa joe. It’s time to step up your coffee game with one of the best coffee grinders around. Investing less money into your coffee marker and more into your coffee grounds will make a world of difference.

While preground coffee is convenient, it gets stale quickly and that diminishes the coffee’s potency and taste. The best way to achieve delicious coffee at home is to grind your own beans with a home coffee grinder.

The last thing you want to fiddle with first thing in the morning is a manual coffee grinder or a hand grinder that resembles a spice grinder. A good electric coffee grinder processes coffee beans consistently and gives you ground coffee that’s exactly the right texture to optimize flavor. Regardless of whether you use a French press or prefer a cold brew coffee maker, these automatic electric grinder devices let a discerning coffee drinker create the ideal coffee ground necessary to concoct their caffeinated beverage.

Keep reading if you’re looking for the best electric coffee grinder that will deliver the good stuff, cup after cup. I’ve selected my three favorites below, followed by a list of the other electric grinders that I’ve put through their paces. The ultimate coffee grinding machines deliver consistent grind quality (be it fine or coarse, depending on the grind adjustment setting), with useful features and powerful motors. They’re also easy to use and easy to clean.

Yes, this buyers’ guide starts at $100, which is by no means cheap, but that’s because I personally tested all of these coffee grinders and I just didn’t like the results from the budget set. (See the testing details below, along with the pros and cons of each and a full list of other models that didn’t make the cut.) I’ll follow up to see if any other bargain grinding machine is worth the trade-off in the future and update this story accordingly.

An ideal coffee grinder produces ground particles that are of a consistent and correct size. By that, we mean that the size of ground coffee particles should match its grinder’s coarseness setting, fine or not. The size of grounds produced should also be fit for the intended brewing method, as outlined within the product manual.

To test each grinder for our coffee grinder reviews, we first hand-wash and dry all parts recommended by the manufacturer. We then set each machine to the appropriate level for grinding drip coffee or automatic coffee brewers (again, as indicated by the manual). Sometimes the manual lacks specific directions. In this case, we select the middle coarse setting for grinding coffee, then bump it up by one more coarse level (from fine grind, such as an espresso grind, to coarse grind). For example, if a grinder has 16 total coarse grind settings (assuming 16 is its most coarse grinding option and 1 is fine), we’ll set it for coarse level 9.

Next we weigh out 10 grams of whole coffee beans to grind. By default our test beans are Kirkland Colombian roast. It’s the same beans we use for our coffee maker tests. (No judgments, please.) When you grind as much coffee and espresso as we do, it pays to be frugal.

Then we run our sample beans through the grinder. We also make note of how long the grinder takes to grind coffee beans. Next, we carefully collect the grounds, then sift them with a two-screen sieve for 60 seconds. For that we use the Kruve Sifter system. Our original Kruve Two unit came with two mesh screens of different aperture sizes (800 and 400 microns). This step lets us measure the grind size and grind consistency of our sample. The Kruve Base has now replaced the Kruve Two, and offers five mesh screens (300, 500, 800, 1,100, and 1,400 microns).

A superior electric coffee grinder or hand grinder will produce grounds, preferably with stainless steel blades, that are mostly between 400 and 800 microns in particle size (at our chosen grind settings). Finally, we weigh the grounds that collect between the two screens (800 microns top, 400 microns bottom).

A bad grinder will grind particles of varying sizes, from large to small. Blade grinders are notorious for this issue. Unlike a blade coffee grinder, a coffee grinder with steel or ceramic burrs typically yields grounds that are much more uniform in grind size.

Additionally, we grind at least two more times. From there, we can record an average optimal yield for each grinder.
