While the type of machine you use to brew coffee or espresso is important, and the type of beans you use greatly influences its flavor, the key to getting the most out of your coffee is how its ground. And a professional quality grinder makes all the difference. The Pro Line Burr Coffee Mill from KitchenAid is deceptively simple. It's stunning hourglass design is home to some of the finest commercial caliber features found in a home grinder, featuring 15 grind settings, a large 7-ounce bean hopper and a glass coffee bin. But getting down to brass tacks, what sets the Pro Line apart is its internal workings. The stars of the grinder are the large, 2 1/4-inch diameter flat cutting burrs made of stainless steel for precision and longevity. Powering the burrs is a low-RPM motor that not only reduces noise, but more importantly the frictional heating that occurs in faster motors that harms or burns the grinds.Housed in die-cast metal finished in a stunning nickel pearl gray or onyx black and protected with KitchenAids amazing two-year hassle-free warranty, this is a grinder thats going to outperform, outlast and outshine the competition. In fact, KitchenAid guarantees it.
