A truly perfect brew starts with ground coffee, but it takes the right grinder to help coffee beans unlock their full flavor potential. The OXO On Conical Burr Coffee Grinders intelligent, built-in scale precisely measures coffee as you grind. Choose from 3 grinding modes: cup mode using pre-set ratio of 8 grams per cup, grams mode to grind the exact amount of grams you like, or manual mode to grind by time. The Grinder's high torque/low-speed DC motor helps keep beans from overheating while grinding; the conical burrs create a consistent and uniform grind for optimal flavor extraction. Whether you like strong or mild, espresso or drip, French Press or pour-over, the OXO Conical Burr Coffee Grinder helps you get the grounds you need to make your perfect cup. It's easy to tare the scale to get a precise read or if you'd like to use a different container for grinding. Here's how you do it: Press and hold the OXO button, until the ring around the button blinks and the menu mode appears (keep holding!). The button light will turn red and there will be a three-second countdown on the display; keep pressing the button until you reach "0". That's it! You're ready to grind!
