NOTE: IF THESE BURRS ARE ORDERED WITH A GRINDER, WE WILL INSTALL THEM, BUT CAN ONLY DO SO FOR ORDERS GOING TO USA CUSTOMERS. The black DLC (Diamond Like Carbon) espresso burrs are the perfect way to upgrade your DF64 or DF64V. Offering precision grinding for both espresso and drip. The DLC coated espresso burrs have a geometry intended to excel at producing espresso. This style of burr tends to work better for medium to dark roasted coffees, but we also find they work fantastic for lighter roasts as well. These burrs are designed to produce a high uniformity coffee ground, allowing the espresso extraction to have high body (viscosity) while also producing a balanced amount of clarity. While these burrs are marketed as "espresso" burrs, they also produce a quality pour over extraction. They are designed for the Turin DF64 Turin DF64V, Mazzer Super Jolly and many other 64mm "Mazzer" hole pattern grinders.
