Best coffee grinder – CNET

An ideal coffee grinder produces consistent, correctly sized grind particles. This means that the size of the ground coffee particles, fine or not, must match the coarseness setting of the grinder. The size of the powder produced must also be compatible with the desired brewing method, as outlined in the product manual.

To test each grinder in our coffee grinder reviews, we first hand wash and dry all parts as recommended by the manufacturer. Then set each machine to the appropriate level for grinding drip coffee or automatic coffee brewers (again, as indicated in the manual). The manual may not provide specific instructions. In this case, he chooses a medium-coarse setting for the coffee grind, and then increases the coarseness level (from fine to coarse, such as an espresso grind) by one notch. For example, if your grinder has a total of 16 coarse grind settings (assuming 16 is the coarsest grind option and 1 is fine), set it to coarse grind level 9.

Next, weigh out 10 grams of whole coffee beans to be ground. By default, the test beans are: kirkland columbia roast. These are the same beans we use to test our coffee makers. (Please don't judge.) If you grind as much coffee or espresso as we do, it pays to be frugal.

Next, put the sample beans through a grinder. It also records the time it takes for the grinder to grind the coffee beans. Next, carefully collect the lees and sift through two sieves for 60 seconds. To do this, we use the Kruve Sifter system. Our original Kruve Two unit came with two mesh screens with different aperture sizes (800 microns and 400 microns). This step measures the grind size and grind consistency of the sample. The Kruve Base replaces the Kruve Two and offers five mesh screens: 300, 500, 800, 1,100, and 1,400 microns.

A Kruve coffee sifting system was used to ensure consistency of grind size.

A good electric coffee grinder or hand grinder, preferably with stainless steel blades, will produce a powder with a particle size between 400 and 800 microns (at our chosen grind settings). Finally, weigh the powder that collects between the two screens (top 800 microns, bottom 400 microns).

A poorly performing crusher will crush particles of various sizes, from large to small. Blade grinders are notorious for this problem. Unlike blade coffee grinders, coffee grinders with steel or ceramic burrs usually produce a more uniform grind size of coffee grounds.

Additionally, crush it at least twice more. From there, you can record the average optimal yield for each grinder.
