Pro Wide range of grinding levels
The Cole & Mason Derwent pepper mill has six preset grind levels, clearly marked and easily adjusted by turning the base dial. It can consistently grind peppercorn at a fine level, as well as at a very coarse one.
Pro Fast grinding
The high-carbon steel grind mechanism in this pepper mill has seven large grooves, that get finer when they get closer to the base (in comparison, most of the other mills have only five). This construction quickly and efficiently moves peppercorn down toward the teeth of milling burrs.
Pro Clear view of the peppercorn reservoir
The clear acrylic middle part of the Derwent model makes it easy to see how many peppercorns are left in the reservoir and when it will need refilling.
Con Needs to be stored in a dark cabinet
The clear acrylic reservoir of this mill exposes peppers to the sunlight, and that may cause them lose their flavor much faster.
Con Grind level markings can wipe off with use
Some users report that the grind level marking on the bottom dial can fade away, especially if often exposed to moisture.
