Grinding for espresso? Let the Virtuoso’s professional-grade 40mm conical burrs perform their magic for a consistent, fine grind. How about a French Press? The Virtuoso can handle that too, with a particle size uniformity that gives you consistency from cup to cup. In fact, the Virtuoso is so consistent at both the coarse and fine ends of the grind range that we consider it to be in a class all by itself — and so do many of the micro- and specialty-roasters who swear by it.
