The Plastic-Free Grinder is an electric burr grinder designed so coffee beans and grounds never contact plastic or aluminum. With 40mm 420 stainless steel conical burrs, a 100g hopper, and 40 stepped grind adjustments, the Grinder has four presets covering espresso, pour-over, auto drip and French press coffee. Also features an ion-probe static reduction system and acoustically dampened stainless steel housing.
