On-demand and doser burr grinders. The grinder does more for the shot than the machine does, which is the part most people get backwards when they split the budget between the two.
Grind consistency drives shot quality, so a commercial coffee grinder with burrs matched to your espresso machine protects every shot; a weak grinder undercuts a good machine.
On-demand grinds per shot for maximum freshness, while a doser suits very high volume service; tell us your daily pace and we'll point you to the right one.
Burrs wear under heavy use and need replacing to hold grind consistency — flat burrs from 64mm to 98mm and conical sets all have their own service intervals, which we'll note for the model you pick.
Two, usually: one professional coffee grinder set for espresso and left alone, one for decaf or filter. A bulk coffee grinder for retail bags is a third machine — an industrial coffee grinder is built for that job and is wasted on a shot.
