Video Overview | Kinu M47 Manual Coffee and Espresso Grinder
Hey folks. It's Steve with Prima Coffee here. Today, we're taking a look at the Kinu M47 hand grinder. This is a premium model hand grinder lauded for its superb construction, all stainless steel materials, and of course, a grind quality that yields excellent results in the cup. So let's take a look at some of these features. Of course, I said we have an all stainless steel construction. Inside, we have 47-millimeter conical steel burrs. They're coated with a proprietary coating that's meant to increase longevity, keep those burrs sharp for longer. The hopper itself holds about 30 to 40 grams of beans. It kind of depends on the density and the roast level that you're using. But it's a pretty nice capacity. Grinding action is really nice, super smooth. There's four bearings inside and Kinu's paid a lot of attention to detail for the precision of design and of course, the actual tolerances for alignment. This is a grinder that feels really solid. And it's not just because it's all steel parts, it's because there's not a lot of wiggle, there's not a lot of slop.Kinu M47 Manual Coffee and Espresso Grinder
It feels very solid to use, even during grinding, but also when it's empty which is kind of when you see those things show up more where you might feel a little bit of burr wobble as you're turning the handle. The actual adjustment of this grinder is micro-steps. It is, there's a dial here and you can probably maybe hear it that it's clicking as I turn it. The dial has 50 steps per full rotation and actually, each of those steps translates to 1/100th of a millimeter. Kinu is actually one of the few manufacturers that will tell you just how much burr travel there is per click or per rotation on the wheel. You can figure that out if you know the actual, you know, screw...pitch, the thread pitch on the adjustment mechanisms of other grinders but Kinu gives it to you right away. Another nice, little detail is that when this grinder is zeroed fully and the burrs are completely compacted together, it actually shows up as zero on the dial. That's, you know, just a nice, little creature comfort to have, but it's really helpful for translating settings across different users on, you know, their own grinders, as well as just coming back to setting more repeatedly on your own grinder between brews.
So in terms of usage, we love the Kinu for espresso and small batch drip. It's really, really nice for espresso honestly. You know, 47-millimeter conical burrs will produce a fairly good sweetness in your shot. Sometimes, it's a little bit tough to remove some of the chalky or maybe even just dry cocoaness out of certain coffees, but with blends, with more medium to slightly dark roasts, with espresso, this is really going to shine. It produces really great body, superb flavor and it can help highlight some of the acidity if you need that. Going into the drip range, that single cup to small batch drip size is really where this shines. Once you get into coarser settings, the Kinu throws a little bit more out in terms of fines, muddies the brews a little bit. Not really that bad but it's a little bit of a, maybe a step down from the good cup clarity you get when you're doing single cup V60s or AeroPress brews, or even just a small Kalita Wave, something like that. Once you get to 300 milliliters to 400 milliliters in terms of batch size, you start to see a little bit more of those fines coming in just because of the way that you're adjusting your grind size. And with certain denser coffees, you might see more fines as well in our experience.
Just to take a look at what grinding with this guy is like, I got a few beans here, I'll dump some in. This steel construction, very large steel handle, a nice, big pommel, makes it really comfortable to grind with. You'll also notice this ABS plastic, they call it a thumb stopper, but really, it's just a finger stopper. I actually prefer to tuck it in-between the kind of nook of my pointer finger as I'm holding the grinder. Grinding is nice and smooth. Again, you really don't feel much slop. You don't hear burrs grinding on each other. They've really done a great job of making sure that all of the parts in this model are really well-machined, really well centered, and just fit nicely and snugly. Grinding through a quick dose here. We also have this magnetic catch cup which is nice. No threads to worry about, there's a whole big array of magnets that actually hold it directly against the ring burr inside the grinder. So that's a really nice convenience feature.
It takes a little bit of effort to pull out, so we haven't really had to worry about it falling out while you are grinding. But just to show off some of the grind quality here, this is sort of a fine drip grind like I might use for a smaller 200 milliliter, 300 milliliter V60 or Kalita Wave. This is a fairly dense coffee. You can see somewhat by the roast level that it's fairly light. And, you know, that would be somewhat of a chore to grind if it were a lesser hand grinder honestly, and if it were, the burrs weren't as sharp, if the mechanism was a little bit sloppier, that might be a more difficult coffee to grind, but that was fairly effortless. Overall, the Kinu M47 is a really a tremendous premium hand grinder. It is more costly than quite a few others. Grind quality in the cup, we like it, but you can get similar results from other grinders. Mainly where we see the Kinu standing is it's really solidly build, you can throw it in a backpack and not worry about it breaking if, you know, things get tossed around by the TSA or something like that.
It has a five year manufacturer warranty and overall, just tremendously good build quality. This is going to last years and years and years without fail. So we really love the quality overall. There's not a lot to really say that would be negative, aside from that price point which is mainly due to the materials and the construction and the quality of the design. So overall, really fantastic hand grinder. We think you'll love it and the results really speak for themselves when you're brewing with it. Thanks for watching. Hey guys. Thanks for watching.
