Grinds Left in Grinder: To maximize freshness, the Encore minimizes the ground coffee left in the grinder. Brewing Methods: The Encore is a great grinder for manual brewing and espresso. Motor: A powerful, high torque DC motor effortlessly drives the burrs. This motor turns slowly resulting in cool, quiet operation and permits long grinding duty-cycles. The circuitry is equipped with an automatically resetting, thermal cutoff switch. Calibration: An innovative burr calibration system ensures that each grinder has the full range of grind. If necessary, the grinders can be user calibrated. Speed Control: With unique speed control, the Encore uses a combination of gear and electronic speed reduction to control the rotation of the burr to 450 RPM. The electronic speed controller is adjustable from 405 to 495 RPM in the event that specific user conditions require modification of the speed. This slow speed reduces heat, noise, and static generation in the grinder. It also ensures that the beans feed smoothly into the burrs. On-off Switch: The Encore has an easy on-off switch. Cleaning: Burrs are easily removable with no tools, making cleaning very easy. Accessories (which may be purchased separately): Esatto: An accessory that transforms your Encore into a grind by weight grinder. Set the weight you want, the Esatto does the rest, weighing the ground coffee to within +/- 0.2g, while grinding, and stopping automatically. Hopper extender: An extension that can add 9 oz. of capacity to the existing 8 oz. bean hopper. Several extenders can be added to get to the capacity you need.
