With a 140 watt direct drive motor, the Rancilio HSD-ROC-SS Rocky Coffee Grinder makes it to the top of this list for its excellent grind consistency of the grind. This coffee grinder is available as a doser model, which provides a consistent and measured grind every time which is especially good for espresso. It’s also available as a non-doser model that’s better for making larger amounts of coffee, but in all other respects these two types are exactly the same.
This pick uses a plate grinder that’s adjustable with up to 20 different grind selections, it is one of the more quiet-running grinders here, and the hopper holds up to half-pound of beans. Weighing in at nearly 20 pounds in weight, it's certainly not going to go anywhere when you’re grinding coffee. This coffee grinder comes covered by a two year warranty but there are several optional extended warranties you can get for an extra cost.
If you are a fan of conical burr grinders, and demand complete consistency in every batch of grounds that you make, the Baratza Virtuoso Conical Burr Coffee Grinder is up to the challenge. The adjustable motor spins the burrs very slowly between 405 RPM to 495 RPM, which assures you won’t have any burned grounds on your hands prior to brewing. This pick uses a relatively quiet transmission that transfers the power to the blades and it also has an auto-stop function if something falls into the hopper and begins to jam up the burrs.
This grinder will hold eight ounces of coffee in the hopper, but there’s an optional nine ounce addition which can be attached. There’s also a pulse function so you can manually grind beans as long as you want, and it comes with 40 different grind selections. The Baratza Virtuoso stands out among other coffee grinding appliances for its functionality and grind quality, so if you want the best conical burr grinder you've just found it.
For a style and design all its own, the KitchenAid KCG0702CU Burr Coffee Grinder is certainly different yet very functional in all respects. This is a plate-style burr grinder, so if you’re into espresso this is a very good machine for that purpose. With 15 separate grind levels you'll always have the grind type you need while the hopper holds seven ounces of beans. This unit looks much like a regular KitchenAid mixer and uses the same reliable 220 watt motor while the exterior of the unit is die cast metal for added durability.
Design-wise, the grinder is a gem with both hopper and grounds containers made of glass to add a very elegant visual touch to this unit. This grinder is available in several colors so you can have your pick of which one fits best with your kitchen décor into any décor. If design, form, and function are priorities for a coffee grinder, put this pick on your short list.
