The Infinity offers the slowest grinding speed in its class that creates less friction and heat build-up, preserving maximum aroma and flavor in any grind setting. Computer controlled special grinding heads cut the angles and shapes of the steel burrs to within 0.1mm precision. Burrs are produced as matched pairs and are hand assembled in Switzerland for precise fit. The multiple gear motor's slow grinding action results in highest precision grinding from Turkish fine to percolator coarse. Also makes the lowest noise.
