Feeding mechanism

Hopper

Hopper-fed grinders hold a large quantity of coffee beans.

  • The coffee in the hopper can go stale.
  • It can be hard to dose an exact amount, as they mostly dose by time rather than weight.

Single dose

Single dose grinders don’t hold any beans, and must be manually fed for every extraction.

  • More work for each coffee cup prepared.
  • The dose can be as precise as you like.
  • Allows for additional prep steps, e.g. Ross Droplet Technique
