What is it? The Weber Key is a single-dosing espresso grinder with massive 83mm TiN-coated Mazzer burrs. Smartly designed and expertly engineered, the Key is compact, beautiful, and powerful. The Key gives you ultimate control over your espresso. Its proprietary TiN coating and Weber's in-house seasoning process make the Key ready to pull shots out of the box with no breaking-in period. The adjustable RPM knob is easy to use as much as it is a game-changer for brewing the most delicate roast profiles. The included Magic Tumbler makes distribution incredibly easy and even, producing back-to-back shots without any channeling or static.  Who is it for? The Key is for the espresso enthusiast, tinkerer, and home barista who is painstakingly obsessive over every single variable in the brewing process. We love these kinds of coffee nerds. In short, the Key is built to stand the test of time; it is your forever grinder.  Why do we carry it? The Key is the most unique grinder we've used in several years, perhaps ever. It's quite rare to see this level of build quality, performance, and thoughtfulness all in one compact package, ready and willing to grind any coffee to perfection. The attention to detail is quite impressive, from its built-in grounds brush, to the tactile stepped adjustments, to the brilliant magnetic Magic Tumbler. The Key is remarkable because it elevates the craft, catapulting us into the future where we can all make better espresso.
