If you're passionate about java, you probably already know coffee grinding 101: fine powder for espresso, coarser grains for a french press, something in between for your handy countertop machine. But with a blade grinder, getting your beans to the right consistency is easier said than done; a coarse grind from a standard machine typically includes a couple of whole beans—and plenty of coffee dust. The best way to step up your game is by switching to a burr grinder. Instead of slicing and dicing, they crush the beans evenly, resulting in a perfectly consistent grind.

If you're dedicated enough to put your money where your mouth is, the Baratza Virtuoso is the answer to your coffee grinding woes. It's designed—and priced—as a "prosumer" device, to be used by baristas and home brewers alike. With 40 settings and a timer switch, you can really customize your brew. Also worth noting: the machine stays cool to avoid heating the flavour out of your beans. Will you really notice the difference? If you're a connoisseur, definitely. Nothing beats the smell of freshly ground coffee, but a truly epic cuppa joe can come pretty close.
