Weber Workshops - Key Mk II

I’ve owned the Key MK2, Kafatek, and Niche Zero (and many more flat burr grinders). I’m sticking with the Niche Zero. For me personally, it’s the best grinder for medium to dark roasts. You won’t get the most complex flavor notes, but you’ll enjoy a rich, chocolatey, nutty, and syrupy-thick espresso. It’s honestly the best and easiest conical burr grinder to use even for other people in the household. Also, this grinder is truly high-quality. With the Key and Kafatek, you must shake, because they produce a lot of fines in the grind and I don’t like to shake my grinds.

Love mine and they are nice and quiet at slower speeds.

I have 2 grinders atm. Sold 1 gave 2 away for free I use both grinders nearly every day. My favorite grinder: Option-o lagom 01 with 102mm mizen burrs. This could be a one and done grinder, does really good for modern espresso, great for filter and immersion brew, and good ( not great ) for traditional espresso and milkies. My more used grinder: Weber key mk2. (Used to be the niche zero). Great high end traditional espressos grinder, wonderful body texture, and sweetness, with a little bit more clarity than the niche. I run 2 grinders, because I can (lol), but really it just convenience thing. I can have my big flat set for grind size that’s more suitable for modern light roast while having my key set for traditional darker roast.
