Set the grind on a Mazzer Mini
To adjust the coffee grind setting, you rotate the large knurled chrome-plated collar that encircles the throat of the grinder .Get added leverage by using the arm on the side of the collar.
The rotation is reluctant because the upper burr carrier is under the tension of three stiff springs pushing it firmly against the adjustment collar.
The Mazzer Mini’s are the only grinder of the six that indicate the recommended starting point for "normal" espresso. The FINE and COARSE arrows point in the direction that you should rotate the collar. The starting point is individually calibrated at the factory and is accurate.
