Kinu's dedication to fine engineering is apparent from just about every angle with their M47 hand grinder. As premium hand grinders go, Kinu's craftsmanship is up there with the best, from the precision-made steel body to the smooth and delightfully clicky grind adjustment, to the ultra-smooth turning of the handle. With a grind range running from Turkish and espresso fine all the way to whatever your coarse needs may be, the M47 is capable of handling any coffee grind you wish.

As its name implies, the M47 uses a 47 mm set of conical steel burrs, coated in their own proprietary material for a longer burr life. Adjustment is micro-stepped, with 50 clicks per rotation of the adjustment wheel, each corresponding to 0.01 mm of vertical movement. Dialing in for various brew methods, we found that 1.5 to 2 full rotations from 0 would be suitable for Turkish coffee, 2.5-3.5 for espresso, 4-6 for pourover, and 6.5-7.5 for very coarse needs like cold brew. Our best tasting brews fell into the finer half of the M47's range - espresso and pourover - as coarser grinds saw slightly more fines. A 20 gram espresso dose takes about 30-50 seconds to grind, while larger doses at coarser settings took us around 20-40 seconds total (coarser is generally faster).

The M47 is constructed primarily of steel from top to bottom, with ABS plastic accents. Its overall capacity comes in around 30-40 grams, depending on bean size and roast level. Kinu advises regular cleaning with only a dry brush or cloth, and disassembly is overall straightforward and easy. Note: the ring burr appears to be press fit in place and cannot be removed. Check the User Manual for more use and care instructions.

Solid as a rock

I bought mine from Kinu before Prima carried them. This is a great hand grinder with a solid as a rock build. You can taste the difference.
