With the Baratza Encore ESP Black, you can grind coffee for both an espresso and filter coffee. The coffee grinder collects the ground coffee in the container. Are you finely grinding coffee for an espresso for your piston machine? Place your portafilter in the holder under the spout. You can set the coffee grinder very precisely. So, you can choose from 40 different grind settings. When you turn the bean hopper, you change the grind size. The grind settings from 1 to 20 are for an espresso. You use the grind settings up to 40 for a filter coffee or a french press. The bean hopper has a 230g capacity for coffee beans. The stand of the coffee grinder is weighted, so it stays firmly in place.
