Grind Setting Guidelines

IMPORTANT: Avoid grinding at the setting mark 0. Forced grinding in this setting could damage the grinder blades. O20 Coffee Grinder allows for 20 different coffee coarseness settings, each a little coarser (0.15mm drop) than the one before. With all these multiple options, the O20 Coffee Grinder can achieve coarseness that works perfectly with all kinds of coffee brewing methods. The adjustment dial ring is equipped with many markings that will match in line with the upper reference mark when a coarseness setting is chosen. To adjust the coarseness, the adjustment dial ring should be turned from left to right; closer it is to the 0 mark, the finer the coffee grounds will be; the closer it is to the 20 mark, the coarser.

Tips for Use

• Grind size will affect the resulting coffee brew; therefore, it’s important to use the correct coarseness for the chosen extraction method.
• Different coffee bean roasting levels might require different coarseness.
• We recommend experimenting with different coarseness sizes until finding the one that fits the required needs.
• The coffee bean jar can be used to transport and measure coffee beans.
• If static is encountered when grinding coffee beans, it might be due to weather or friction. The seasoning of the grinder core will reduce this issue, but there are methods like spraying a light mist of water on the coffee beans before filling the hopper.
• Try to adjust the setting before adding the coffee beans to avoid any jamming.
