Details

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.

Excellent Grinder, built like a tank

I had to upgrade my grinder to start making espresso, so I went for the Kinu M47 I love the weight of the grinder, the way it looks, and how it fits in your hand. Plus the grind measurement is simple to use I would definitely recommend this grinder, though it's not a good option for travel due to its size and weight

Got my Turkish

Excellent. My main concern was being able to get a “Baby Powder” fine grind for Turkish coffee....and I got it.

Good enough.

I'm not good at brewing coffee and speaking English. It's a little heavy. Adjusting the size of ground coffee is very easy. The price is high but the satisfaction too.

easy to use, phenomenal control over grind size

I have used the Kinu for espresso, single cup pour overs (with V-60 and Kalita Wave) with a Chemex making coffee for two. It has performed beautifully in all settings. I'm not sure I would want to use it for espresso every time I make one (making 2-4 doubles a day), but I really enjoy it as part of my pourover routine/ritual. Weighing out and grinding the beans takes less time than bringing the water to temperature, so it does not slow down the process. It grinds very smoothly--there is no wobble in the grinding mechanism and the grounds are very uniform. The heft of it might be a problem for some, especially if you are looking for something to take on the road or trail. But if you are looking for a manual grinder to use at home for a wide range of applications, I don't think you can do better thank the M47.

Excellent grinder

This is an excellent hand grinder. The grinding motion is smooth and easy. I add 15 - 25 grams and it takes around 30 seconds to grind through. The result is a very consistent grind.

Kinu M47 is Awesome

I was looking for a manual grinder without electronic parts ever since my Baratza Encore broke down and decided to try this out. The usability and simple design of this grinder is excellent. It's very easy to clean with few parts and provides very consistent grinds for espressos all the way up to drip coffee brews. The only negative issue I had with the grinder is because they can't incorporate all grinding settings within that small of a grinder, you have to make full rotations to reduce or increase coarseness and it's very easy to forget what rotation you were on the previous day so you can know how much to adjust for a different brew the next day. Other than that this is an awesome tool I wish I could have had earlier coffee toolkit.

Incredible grinder

I personally found this grinder too heavy but that’s because it will last multiple lifetimes. The adjustment is the finest I’ve seen, truly a step less adjustment. At first I thought it was a bit expensive, but given the build quality, I think it’s underpriced.

M47 MANUAL COFFEE AND ESPRESSO GRINDER

I looked at multiple manual coffee grinder. The M47 is constructed of stainless steel body which is very strong, compared to other with aluminum bodies. The simplicity of use is excellent. You really don’t kneed to unassembled. The steel bur grinders work as advertise, grinding to the perfect setting. Adjustment are easy, just remember to tighten the top knob tight. It will not lose it setting if it is tight. I would highly recommend this to anyone who like to grind their own coffee beans.

Very pleased.

I had been using the Knock Aergrind for 1 year prior to purchasing the Kinu M47. While I like the Aergrind, the M47 is on a different level. It is much larger, heavier, and feels very premium. I wanted to get as close to the quality of the EK43 without spending $2,700. That’s the only reason I bought the most premium handgrinder that I could find. $335 is much more appropriate for my budget. I like the feel of the grinder in my hand. I like that I can just pour the beans directly into the top of the grinder without having to remove the handle and lid like I do with my Aergrind. Pro tip: weigh beans into a different vessel, and then pour into the grinder. It’s a lot easier than trying to pour the beans directly into the grinder from the bag. I personally use the grounds catch container from my Baratza 270. The grinder produces great cups, and I have no buyers remorse. I enjoy using this product every day.

Kinu M47

A++ So happy I went with a Kinu. Works great with my Flair Pro. Grinds beautifully and adjusts incredibly easily, can usually dial in new beans in around 3 shots. Cleaning and dis/reassembly is super easy. I didn’t realize how much I would appreciate the smaller details like the thumb stop or magnetic catch cup. One thing to watch out for is if you’re not paying attention your wedding (or any) ring will scratch up the body pretty quick.

Fantastic. Pulls wonderful shots on the Spirit at work and is just as great for pour overs at home. Really impressive piece of equipment. Quality and finish never cease to amaze me and all my coworkers wish they had one.

Good grinder but catch cup not perfect.

The grinder itself is amazing. Everything you expected and more. Heavy duty is what comes to mind. Grind consistency is nearly perfect. Grinds 15g of light roast in a lazy 20 seconds. Beautiful design. Thumb stop works well but isn’t really necessary because it grinds so smoothly and easily. My complaint comes in the catch cup. It’s magnetic and they came a little proud of the cup surface. A couple of times, the magnet pills slipped out of the cup and were stuck to the grinder. I had to pull them off and insert them back into the cup. I pushed them all in with my thumb and they went in a millimeter below the cup’s surface. I noticed that the magnetic force was much weaker. One day I was nearly done grinding and the cup dropped spilling all the grinds on the floor. It got dinged up but still fit into the grinder fine. I had to use a metal right angle pick, push the conical sleave down and push the magnets up so that I could push them back down flush to the surface. It ended up marring up the conical guide and has a dent on the bottom from the drop but so far it hasn’t lost a magnet and holds onto the grinder well. I don’t understand how it passed quality control from the factory. Kind of a shame for a $329 hand grinder.

defective magnets in catch cup

Each of the last 3 times I have used the grinder, another of the 11 small magnets that hold the catch cup to the body of the grinder has come loose and stuck to the inside of the grinder. (So now I have 8 of 11 magnets remaining in the catch cup.) This is after less than one week and 10 uses on the grinder.

Superb manual grinder!

Purchased direct but still wanted to post a quick comment. Worth every penny, German engineering and over built. Potential buyers will not be disappointed from a standpoint of performance or quality of design. If you just want to make drip go for the Phoenix, if you want great espresso then buy an M47, advice given to me, and passed on!

Solid, Precise and Grinds Quickly

The Kinu M47 is wonder to use. I've owned others and nothing has compared to the precise engineering and grinding. It is quite heavy but you get used to it and enjoy the solid feel it provides. I use it for different grinds but primarily a medium for pour over. It grinds 30g within about 20 secs and the grinds are very consistent. Prima advises the burr will last a lifetime and I believe it based on how it works. I use a simple brush to clean the grinder but only once every 2 weeks do I disassemble the unit to brush all components and the internal burr. It is then simple to put back together and get the grind setting back to 4.0 for my pour over. Thanks.

Design, Build, and Feel like a Curta Calculator...

from the time of handheld, hand-cranked calculators, or a Leica from the time of chemical photography. The M47 is a beautiful thing. After a short break-in period, the espresso grind is as good as it gets. Same for æropress grind.

Amazing! Wish it had a lid though.

Amazing grinder. The upgrade from a knock off Polrex is crazy. It grinds my beans SO FAST it’s crazy. The driveshaft has a beautiful click like a nice bicycle crank or a ratchet. Love love love this. Only thing is I wish it had a lid.

The awesome Kinu M47 Manual Coffee and Espresso Grinder!

I own the Flair Classic Plus (includes a Stainless Steel Tamper), the Stainless Steel Piston, and the Bottomless 2-in-1 Portafilter. I like to leave it disassembled with the parts lined up on a folded paper towel, and the screw you installed, as it feels more solid to me. My grinder is the awesome Kinu M47 Manual Coffee and Espresso Grinder which I purchased at Prima Coffee. This is the latest model which comes with the 11 magnet cup and a zero setting on the burrs. I am finding a setting of 3.4 works great with the Flair. It is so easy to take apart and clean using a 3/4" mop paintbrush made with goat hairs. I love high quality manual devices!

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.
