Manual Spice Grinders

We tested six spice grinders by grinding measured amounts of cumin seeds at the finest and coarsest settings and then grinding a teaspoon of dried rosemary needles into a fine powder.

Westmark Spice Mill with Ceramic Grinding Mechanism

Powder and coarsely ground spices produced by this grinder were consistent in size, but it was in the middle of the pack in evaluations for speed. Its real flaw: Herbs and water (postwashing) were trapped, hidden, inside the gear mechanism. Both were impossible to detect but mixed into the contents of the jars without warning.

What You Need to Know

Although we appreciate the convenience of preground spices, their flavor and aroma are more potent when you grind them fresh. But our favorite electric grinder, from Krups, can feel oversized for grinding just a teaspoon or two. Are manual spice grinders the answer to quick, small-batch ground spices? To find out, we purchased six models (priced from $8.48 to $24.22), hopeful that we could find one that could consistently transform whole spices into a fine powder or crush them coarsely, and that was simple to load, adjust, use, and clean. We put each model through its paces, grinding measured amounts of cumin seeds at the finest and coarsest settings and then grinding a teaspoon of dried rosemary needles into a fine powder. In each test, we timed the process and evaluated general ease of use with every grinder. 

Most of the models looked and worked a lot like pepper mills: You load a clear glass jar with spices, screw on a stainless-steel or plastic grinder housing, and hold it steady while you twist the jar. The majority of grinders had a small knob on the grinding mechanism that adjusted the space between the two grinding elements and thus the size of the grind. The one model that lacked this feature was a failure, with the bulk of both the cumin and the rosemary falling through the mechanism unground.

That’s not to say that we were satisfied with the other models, which were, in a word, exhausting. Grinding 1 teaspoon of cumin to a fine powder took between 1 and 4 minutes. It was generally quicker to produce a coarse grind, but the slowest model still clocked in at over 1 minute. With most models, the grinding gears clogged easily with spice residue and halted grinding. When this happened, we had to loosen or even dismantle the grinders to shake out the clumped grounds and wipe off the gears—adding yet more time and frustration to the process. We also found that whole herbs and spices became trapped or hidden in the gear mechanisms of some models; as a result, cumin seeds drifted into the rosemary and contaminated that batch of ground spices. A similar problem arose when we washed the grinders: More than a week after washing, water still dripped out of the works and dampened our freshly ground cumin.

Ultimately, we can’t recommend any of the models we tried. The best of these models, from Kuhn Rikon ($15.10), produced consistent results at fine and coarse grinds, and its wide base made twisting comparatively easier, but it’s still too slow and is prone to clogged gears. We’ll stick with our favorite electric spice grinder, the Krups Fast-Touch Coffee Mill ($17.99). Not only is it quicker than the fastest model (a teaspoon of perfectly ground cumin took just 45 seconds), it also works with just a gentle press of a button, is simple to clean, and is cheaper than many manual models.

Kuhn Rikon Vase Grinder, Kitchen

The base of this model is wide and ridged, with a piece of contoured black plastic that offers good grip and extra output with every twist. As a result, it was the quickest to grind a teaspoon of both cumin and rosemary. That said, twisting a grinder for a minute or more for such a small amount was unacceptable even to patient testers.

Linden Sweden Tulip Spice Grinder

In all of our tests, twisting the gear housing felt bumpy and rough. A few fibrous bits remained in finely ground cumin, and a few large pieces of rosemary fell through during that test. Rosemary also jammed the gears. When this happened, we had to stop to dismantle the product and clean the grinding mechanism before proceeding.

Kyocera Everything Mill Adjustable Grinder

This slender model was tiresome to use. Testers noticed a few larger, fibrous bits of cumin and rosemary mixed in with the finely ground powder in both tests. Grinding rosemary to a powder took more than 3 minutes, but the grinder didn’t become clogged when grinding cumin.

Cole & Mason Kingsley Herb and Spice Mill

Finely ground cumin was exceptionally powdery and uniform. If we had unlimited time, wrist strength, and patience, this grinder might have met our expectations. Unfortunately, the gears became clogged quickly and prevented it from working. It was especially problematic with rosemary. After more than 5 minutes of twisting yielded less than ½ teaspoon, our frustrated tester gave up.

Norpro Spice Grinder

Instead of a transparent jar, this grinder had a white plastic base with a tiny tube for whole spices. The capacity was small, and we struggled to fill the reservoir and twist the sharp metal disk and lid in place. Once it was attached, lots of whole herbs and spices slipped through the opening at the bottom. Another complaint: There was only one grind size, and it was far too large to use in most rubs or even as a flavoring in a dish.
