Make your great grinder even better with Baratza's innovative Esatto, an accessory that can turn your Baratza grinder into a real time, weight-based grinding machine. Set the weight you want and the Esatto does the rest, weighing the ground coffee within a tenth of a gram while grinding, and stopping automatically. Designed specifically for use with your Baratza Encore, Virtuoso, or Preciso, the Esatto has three user-programmable buttons for repeatable, one-touch grinding.
