I have hands on experience with many good hand grinder like the Lido E, Hausgrind, Comandante Mk3, OE Pharos, Mahlgut and HG One. Now I would like to introduce two very interesting new hand grinders. Meet the Kinu line!

(Thanks to my coffee friend Bobbee for making this unboxing video!)
And the Kinu M68: https://www.facebook.com/media/set/?set=a.1798766017071645.1073741829.1797322603882653&type=3
A couple of weeks ago I watched some youtube movies showing the prototypes. I then got in contact with the moderator of the Romanian coffee forum (Liviu Fratila) who has been testing these grinders thorougly. The members of the Romanian coffee forum have been giving feedback to the manufacturer during the development of both grinders. Liviu gave me more details and brought me in contact with the manufacturer. And so it happens that I am looking now at two amazing grinders on my kitchen countertop!
Both are excellent grinders. In my opinion the Kinu grinders are not just "me too" grinders but rather unique in their kind. Material choice, build quality and precision alignment (they have a very interesting bearing construction to guarantee extremely tight tolerances) are as good as it can get.
Let me start with the M47: It is a very solid piece of stainless steel. The used burr set is a 47 mm conical from Italmill. Hence Kinu M47. They claim tolerances of just 0.02 mm. Even at much finer than espresso grind I get zero burr rub. So I am convinced. Grind adjustment is stepless and does not slip. Just turn the dial + or -. It has a mark to remeber settings. The touch and feel is great and a nice feature for me is the thumb rest. It really helps to stablise the grinder in use. The grinder is in my opinion not only very suitable for slow coffee but a serious espresso grinder as well. It is quite easy to grind with it in the espresso range. Until now my favourite hand grinder for slow coffee is the Comandante MK3. My preliminary conclusion is that the M47 is at least as good. Of course everything is subjective but for me the Kinu M47 is the best package at the moment. It would be nice to compare it with either the Helor 101 and Bravo mini but I do not have or had one of these in my hands. The European price for the M47 is 249 euro's (19% VAT included). Launchprice will be 209 Euro. So slighly over the Lido and Comandante in my country (The Netherlands). Reasonable given it's superior fit and finish and more expensive material use. My coffee friend Bobbee is planning to share his experiences with this piece soon on this forum as well. He has written a nice review on the Dutch forum already: http://koffiepraat.nl/forum/viewtopic.phpf=8&t=7472
Over to the M68. As one might expect it has a 68 mm conical burr set. Again from Italmill. It's from their "Food Friendly" line. These burrs should last longer than average and give (certified) no contamination. I do not think that contamination is a problem with other burrs by the way. As with the M47 alignment is just perfect. Again no burr rub in the sub espresso range. And the vertical cranking arm turns very smooth. A rather unique feature is it's "gear box". Unlike other hand grinder it has a 2.4:1 in stead of 1:1 transmission. This translates in easier turning without suffering too much on speed. I have noticed that I need considerably less effort with this Kinu compared to the Mahlgut (great grinder as well!). Especially at the beginning. I find the Mahlgut quite challenging to start up. Regarding speed: For my Strietman CT1 I typically grind 15 grams in about 20-25 turns (without seasoning the burrs properly yet). Quick enough. On flat surfaces the grinder can slide a bit so I have ordered the Amble2 antislip mat Erik has suggested for the HG One. But I have no trouble to stabilise it so far without an anti slip mat. Just use the free left hand for some down force. Nice details are the magnetic funnel holder and the magnet holding the grounds bin on it's place. Grind setting is stepless of course. And size is pretty small. Much lower than the HG One for instance. The M68 costs 649 euro's (19% VAT included). Launchprice will be 599 Euro. That is significantly cheaper than the HG One and Mahlgut. At least in the Netherlands.
After one week of heavy use I really like these grinders. I am getting great extractions with both of them. Just some RDT to get rid of static and an even and fluffy grind is guaranteed. No clumps. The M68 is even more fluffy than the M47. No signs of channeling or Spritzers whatsoever and I am not using any mixing or shaking devices. For me they are the prefect hand grinders. Regarding taste: Too early to draw definate conclusions. Both make up for a great cup. Shots with the M68 tend to be a bit brighter in comparison with the M47.
The Kinu 47 is for sale already and on stock. A new series of their M68 is almost finished. Their website is still under constuction but will be launched soon (one or two weeks from now).http://www.kinugrinders.com
Meanwhile you can find more info on their facebook page and contacting Kinu is possible via firstname.lastname@example.org
. I have found their customer service to be very polite and extremely helpful. They are so passionate and proud about their products. Rightly so!
By the way in their line up of grinders there is the Kinu M38 as well. It shares the same 38 mm conical burr set seen in many other hand grinders ( Lido 1, Hausgrind, Feldgrind, Rosco and Bravo mini). I have no personal experience with this one yet. But given their focus on tight tolerances and quality control and the proven track record of this burr set I have no doubt it will be a fine grinder as well. Price: 182 Euro.
All the best to all!
PS. Many thanks to Liviu, Cosmin and mister Biernatek from Kinu for their patient help!
