Spice grinders can have different grinding mechanisms, but they all have the same goal: efficiently grind whole spices into fine powders. “As a general rule, whole spices will have a much longer shelf life because the volatile oils that are responsible for flavor and aroma remain intact,” said Alex Wilkens, spice expert at The Spice House.
While operating a spice grinder doesn’t require a lot of prep work, we still recommend grinding your spices before you start cooking. If you like to make your own spice blends, or if you find yourself reaching for a particular spice frequently, you can grind larger quantities once a month, suggested Uttam Mukherjee and Aakanksha Sinha, co-owners of the Spice Waala restaurant. Once you grind a spice, you have a month or so before the flavor starts to wane.
We tested five spice grinders and two pepper mills with three different spices to identify the best options currently on the market.

Our testing methodology
We chose to test cumin seeds and cloves as small and medium sized spices, respectively — both with uniform shapes. We also ground cinnamon sticks broken into shards to see how the grinders handled large, irregularly shaped spices.
For recommendations and tips on what to look for in a spice grinder, we interviewed Alex Wilkens of gourmet spice purveyor The Spice House, and Uttam Mukherjee and Aakanksha Sinha, co-owners of Spice Waala, an Indian restaurant in Seattle. After speaking with these experts and conducting our own research, we settled on our criteria:
Speed: We filled the grinder cup halfway with each spice and ground for ten seconds. At this point, we evaluated the consistency of the grounds by eye. Then, we ground the spices in 10 second intervals, and evaluated them for consistency after 20 seconds, 40 seconds, and 60 seconds.
Consistency: We used Kruve sifters — fine mesh sifters calibrated in microns for coffee grinds — to measure consistency. The 200, 250, 300, 350, and 400 micron sifters are used for espresso, a powder consistency. We sifted store bought cinnamon and cumin powder through the 200, 250, and 300 micron sifters to see which was best for powdered spices. The store bought powder easily passed through the 250 sifter, so we identified that as the goal for the spices we ground ourselves. When measuring the spices, we started with larger sifters and moved to smaller ones until the grinds …read more
