A coffee grinding apparatus which measures a quantity of coffee for grinding as a function of time and which is calibrateable to accurately discharge a selected weight of ground coffee. The grinding apparatus includes at least one storage hopper in gravity feed relationship with a dispenser and a grinding mechanism. The apparatus includes a control circuit coupled to the dispenser for selectively operating the dispenser to dispense a desired quantity of coffee beans into the grinding mechanism. A selection device is coupled to the control circuit to allow a user to select a desired weight of ground coffee to be produced by the grinding apparatus. A calibration assembly is coupled to the control circuit, which calibration assembly includes controls for entering the actual weight of the ground coffee to be discharged and a microprocessor which includes a circuit for calculating a correction factor to calibrate the grinding apparatus to accurately produce the selected weight of ground coffee.
