Baratza Virtuoso Coffee Burr Grinder Review
We think this is the best precision burr grinder for a simple reason: We love the burrs.
The pro-grade, solid-steel conical burrs are 40 millimeters in diameter. They're equipped to produce exact grinds, literally down to the micron. Adjust the bean hopper to one of its 40 settings, and the burr will produce a fine or coarse grind from 200-1,200 microns. While the burr is doing its work, the push-button machine is doing its work: making sure the beans don't heat during the grinding process (and, thus, losing some of their flavor).
And here's a note your ears and neighbors will enjoy: This model was redesigned in 2012 to reduce motor noise via a thermo-plastic drive gear.
