New grinding disc development for the commercial sector

We would also be happy to develop new grinding discs for you according to your requirements and quality specifications, which are perfectly matched to your coffee grinder or fully automatic coffee machine.  


Our quality standards

Our claim is the highest quality.
To this end, we work closely with the Technical University of Hamburg, among others, in the field of particle technology.
Continuous quality checks ensure compliance with our quality standards and we are constantly developing them and the technologies we use.


Grinding disk coatings

With our coatings specially developed for coffee grinding, we achieve an optimized particle distribution and a significantly longer service life for our grinding discs.


Optimized particle distribution

The result of the optimized particle distribution is a greater variety of flavors and a wider range of settings for your coffee grinder and fully automatic coffee machine.
Nothing stands in the way of a next-generation (Third Wave) coffee and espresso experience. This has already been confirmed by a multiple Barista Champion as well as other coffee experts.
