Reviewers call the Unicorn Magnum the best all-around pepper grinder. The refill opening is wide and, at 7 tablespoons, the pepper mill's capacity is generous. The acrylonitrile butadiene styrene (ABS) plastic housing wipes down easily with a damp cloth, and there's a tray to catch pepper dust. What's more, this Massachusetts-made mill is guaranteed for life. The Unicorn Magnum has a smooth, round head that can be slippery to turn with wet or greasy hands; if you want a grinder that's easier to grasp, reviews point to the Unicorn Keytop (*Est. $20), which has a flat knob at the top instead of a smooth head. If you're looking for a larger pepper grinder, reviews call the Unicorn Magnum Plus (*Est. $45), which has a 15-tablespoon capacity, an excellent choice.

Editors review only manual pepper mills because, they say, the electric pepper mills they tried didn't work. They rate seven pepper mills on performance and design. Top-rated pepper mills have a large output and easy-to-use grind-adjustment settings.
