Coffee grinders come in all shapes and sizes — price "size" included. As an ex-barista, I've used countless commercial-level grinders, and now as Tom's Guide resident coffee expert, I've reviewed tons of home-barista grinders.
But the most premium grinder I've ever reviewed is the revered Mazzer Philos. Just the slightest utterance of this name will send fellow coffee nerds into frenzies. And it's $1,500. While yes, expensive, the Mazzer Philos is also a beauty. Just look at it (scroll up, on your left). With a 0.8% average retention, the Philos is also the lowest-retention motorized grinder I've ever tested.
