The Sette Series debuts a revolutionary new grinding technology. Designed and perfected in Liechtenstein over a period of 8 years, this technology sets a new standard in simplicity, efficiency, and durability. This new mechanism has the outer burr rotate and the inner burr is fixed, a truly revolutionary design. The design of this mechanism doubles the efficiency of similarly sized grinders. Coffee passes straight through the grinder, vertically, and drops directly into the grounds bin or your portafilter.
