Maybe things got rolling a little fast with my last post about making the perfect cup of French press coffee. So let's back up a sec.

Some readers had pretty visceral reactions to my suggestion that they ditch the ol' whirly grinder in order to make a tastier mug of French press joe, and I understand: Blade grinders are cheap, burr grinders can be expensive! But not all decent burr grinders will chop your wallet as well as they chop your beans, and your cup quality should skyrocket as a result.

Learn why and see a ridiculous video of me after the jump.

A blade coffee grinder, which is the standard for most home coffee drinkers, has a food processor-like blade that swings around and chops up coffee beans. The grinders are usually fairly inexpensive and do the job of grinding up beans faster than you could do it with a hammer, but they are not necessarily very efficient, nor do they come close to getting the coffee beans evenly ground. Burr grinders, which are more expensive but crush the beans instead of chopping them up, produce even grounds and will generate the most consistent flavor in coffee - not to mention that they offer a range of sizes (from powdery fine to coarse) that work with different types of coffee makers, including espresso machines and french presses.

The Wall Street Journal's catalog critic sat down and tested a number of burr grinders to see which ones performed the best. The less-than-satisfactory grinders included the Capresso Infinity burr grinder, The Krups Burr Coffee Mill and the Cuisinart Automatic Burr grinder. The top performer was the KitchenAid Proline Grinder ($200), which produced grounds to exacting specifications and stored them in a nice glass container before use to eliminate the possibility of static charge making grounds adhere to the side of the container, as they sometimes did with plastic container models. The model given the "best value" designation was the Solis Maestro Burr Grinder ($115), which performed perfectly, but had a plastic grounds container that could have a minim static charge. In fact, it is the grinder that I use and it always does an excellent job - even with dark-roasted, oily beans that can jam up some other grinders. The KitchenAid would make a great Christmas gift "for coffee geeks," but the Solis is probably the way to go in terms of both price and performance.
