What do I need to do before using the grinder for the first time?

The 1Zpresso grinder is ready to use straight out of the box. Adjust the grind setting and enjoy. Your purchase will also come with 100g of old coffee for you to play around with and adjust the grind settings so that you don't have to waste your precious Rogue Wave coffee.


How do I adjust the grind setting?

[Internal / Top Numerical Adjustment]

By twisting the adjustment dial in a clockwise position until reaching the lowest grind setting, then simply move the adjustment dial counter-clockwise to your preferred grind setting. More rotations produce a coarser grind.

[External Numerical Adjustment Ring]
Twist the adjustment dial to adjust the grind setting. The Red Dot pointer above the dial indicates the setting, much like an electric grinder. The higher the number, the coarser the grind.


How do I clean and care for my grinder?

All 1Zpresso grinders can be easily dismantled without tools, allowing for thorough cleaning without the need to re-calibrate the burr after reassembly.

  • The grinder should be cleaned with only a dry brush and blower. 
  • Do not clean the grinder with water!
  • Once a month, dismantle the grinder and perform a thorough cleaning. This will maintain the best grinding results and, thus, the best tasting coffee.


There is a small scratch on the surface of the catch cup, is this normal?

Manufacturing is carefully controlled to limit substantial cosmetic defects, but very small imperfections on the surface of the metal are to be expected in the aluminum anodizing process.


Are variations in the grain of the wood of the handle knob considered normal?

As a natural product, wood exhibits variations in grain and smoothness that synthetics do not. These variations are considered normal and desirable.


Do you offer a warranty or guarantee on your product?

All 1Zpresso products include a one-year limited warranty covering normal usage.


What can I do if I have technical problems?
