First class material, excellent quality and precise function is what the name Zassenhaus, the leading manufacturer of manual coffee mills/grinders, has stood for since 1867. The Zassenhaus coffee mills are built to ground coffee the PERFECT way. The stepless adjustment guarantees a consistent uniform grind from coarse to powder fine with the least heat build up in order to protect the most delicate flavours of gourmet coffee. Zassenhaus Espresso Mills are manufactured to the highest standards and are backed by a 25 year manufacturers guarantee on the grinding mechanism. This black beechwood Zassenhaus Santiago Espresso Mill/Grinder measures 9cm/3.5in by 14cm/5.5in by 20cm/7.9in. The coarseness of the grinds can be varied by using the knurled knob located below the crank.
