1ZPRESSO Grinder | K-MAX



1ZPRESSO is a newer company out of Taiwan, founded by a group of coffee lovers with a shared background in engineering. In the words of 1ZPRESSO, 'we develop innovative manual coffee grinders with a passion for specialty coffee.'

1ZPRESSO grinders are designed for clarity of flavour notes for pour over or filter brews, while still being suitable for home espresso, aeropress, and french press brews.  

With their award winning design, 1ZPRESSO grinders all have an external adjustment ring and a new heptagonal 48mm stainless steel conical burr and dual-bearing shaft for stability and consistent grinds. 

All 1ZPRESSO grinders incorporate a quick disassembly design, which allows for quick and easy cleaning with no need for tools or recalibration. 

The K-Max is most suitable for pour over and espresso brews with its 48mm stainless steel burrs and finer adjustment-dial design.

Equipped with a top adjustment dial for accessibility, the K-Max has 9 numbers and 90 clicks for grind precision. Each click moves the grind size by 22 microns.  

The K-Max comes with a magnetic catch cup for ease of use and a curved handle level / ball knob for extra comfort. 

The K-Max grinder includes a cleaning brush, air blower, rubber grip band, and cylinder case.

Please refer to the 1ZPRESSO user manual before using.
