ROK GrinderGC - Manual Coffee Grinder. Grind Coffee Beans by Hand at Home.

Si sabes algo mas de cafe, te darias cuenta que este molino no vale mucho. La base empieza a resbalar despues de dos meses y se me rompio uno de los engranajes a los 6. Antes recomiendo otro molino.

I have used this grinder for 2 to 3 years and have enjoyed every cup. Robust and flavorful without bitterness. Previous grinder was electric, not a drop through and was a pain to clean. If I didn't clean it, over time I believe I tasted rancid oil and also a bit burnt from the high speed heat. This grinder is very easy to clean I clean it weekly. And no way do I crank fast enough to generate heat. Absolutely no off flavors. My only criticism is that it does get very staticy. I spritz .5gr of water per 30gr of beans, does the trick. But every time I grind I wonder if the original metal base and cup didn't discharge the static inherently.

Nach langem Studium verschiedener Empfehlungen und Kritiken habe ich mich für Risiko entschieden und diese noch nicht bewertete, mit 177€ relativ teure Handmühle gekauft. Leider ist die schwarze Bodenplatte nicht wie zu vermuten aus Aludruckguss, sondern aus schnöder Plastik. Ebenso wie die unter der abnehmbaren (Plastik)Abdeckung befindlichen Kegelräder des Antriebs. Na gut, wenn das Material auf Langlebigkeit ausgelegt ist, soll es mir recht sein. Auf der Unterseite sind zwei Antirutschstreifen, die gut funktionieren (eventuell muß man mal ein paar daran haften gebliebene Kaffee- oder Zuckerkrümel, die daneben gefallen sind, abwischen). Der Mahlgrad ist nicht einfach einzustellen, auf den Fotos sieht man das nicht vollständig entgratete Einstellrad und ein paar Kratzer daran. Da das Rad besonders im Bereich "fein" recht straff geht, empfehle ich ein Küchentuch zu benutzen. Eine Anzeige des Mahlgrades gibt es nicht, es nutzt auch nichts, mit dem Edding Markierungen zu machen, da das Rad sich beim Kurbeln mitdreht. Daher habe ich mir eine Mahlgradanzeige mit Blechstreifen, Klebeziffern und einem Magneten gebaut, der über der jeweils eingestellten Zahl, im Foto die 8 steht. Um ein System zu finden, habe ich das Rad im Uhrzeigersinn soweit "zu"gedreht, bis es fest war, dann drehte sich auch die Kurbel nicht mehr und ab dieser "Nullstellung" zähle ich beim Drehen gegen den Uhrzeigersinn die Rasten. 1 = feinster Mahlgrad für Räuberkaffee, 8 nehme ich für Filterkaffee. Vielleicht nicht wirklich hausfrauentauglich, mir macht das aber Spaß. Auch lustig, daß man dem Mahlwerk zuschauen kann, aber leider spritzen Kaffeebohnenstückchen immer wieder heraus, daher hab ich mir aus 2mm dickem Silikon eine Abdeckung gebaut. Bin noch auf der Suche nach glasklarem Silikon. Für 32-35g Kaffeebohnen (viel mehr paßt in das Mahlwerk und in den Auffangbecher darunter im Betrieb auch nicht hinein) benötige ich ca. 110-130 Umdrehungen an der Kurbel. Die Zahl der Umdrehungen ist seltsamerweise scheinbar unabhängig vom Mahlgrad. In Stufe 1 ist es natürlich etwas schwergängiger, aber durch die Hebellänge und die ergonomisch natürliche Drehbewegung senkrecht geht das Mahlen relativ leicht. Die Mühle behalte ich! Wie schon gesagt, ich hab Spaß dran und ich freue mich schon auf den nächsten Kaffee!

Easy to use, could do with numbered positions, but once you dial it in you kinda leave it, till the next time you need to dial in. A little rough first couple of uses, and then spins more freely

Delighted with my purchase. This hand grinder is everything that I wanted and exactly what I needed. I found it so easy to use and I was able to dial in espresso immediately! I will start by saying that I am biased in that I wanted a hand grinder and I wanted this hand grinder. I have a greater tolerance for any potential "negative" points. I will start with the pros. Pros--- Looks fab in the kitchen. Super easy and simple to use. Super easy to clean. Zero fuss to the machine. Zero grind retention. Super easy to adjust, I am sticking with the stepped adjustment and I dialed in my espresso grind immeadiately. In my opinion, I have not sifted the grinds, the grind is consistent. I am hitting my brew time and flow rate repeatedly. I am getting so much more flavour from my beans when compared to my similar priced electric burr grinder, baratza encore. I have never owned an more expensive electric grinder and thus cannot compare. I grind through 36g of in a few minutes, which is about the same time as it takes for my espresso machine to warm up. It is marginally slower than using my baratza encore. I have not used it to grind coarse coffee and I cannot comment on this. Not cons for me--- Prior to purchasing, I agonised over some of the cons. Static was the main concern. Retention, somewhat linked to static, was another concern. Popcorning beans was another concern. They turned out to be such non issues. It's actually funny how little concern I have for these points now that I own the machine. For where I live and the beans that I use, I do not have an issue with static. I have not used the water droplet method as I do not want grinds caking up in the grinder. I simply grind the beans as normal into the grind cup. Then, when I have ground all the beans and before I remove the cup from under the grinder, I lift the cup up slightly and spend up to 10seconds tapping the cup from left to right against the base of the grinder where the grinds exit from. A kind of ding a ling motion and noise if that helps you picture what I do. This gives the static enough time to disperse and knocks any retained grinds from the grinder. I do not have any retention issues. Following on from the previous point, I do not have any static related retention issues. I put 18g in and I get 18g out. I put 36g in and I get 36g out. I am fairly confident in my hario weighing scales accuracy. If I loose anything then it is due to popcorning and usually 0.1 to 0.3 of a gram......but only if I don't get any bean pieces back into the hopper before finishing my grind. Cons--- Popcorning is another non issue for me but it does happen. Therefore it is a con. I grind slowly, I did not buy a hand grinder to grind quickly. I rarely get popcorning. If I do I will loose 2 full beans or a few fragments from a single bean. Normally I just put them back in. It's not every grind. I am sure that adding more speed would cause more popcorning. The grinder needs two hands to use. I have found that it takes a little getting used to, to know how to hold it so that it doesn't move about when cranking the handle. I have almost perfected a technique now that minimises effort and increases stability. I like to have the grinder at an almost 45° angle to my body. This allows me to put minimal pressure down with my holding arm at a key crank point while the other hand cranks. For most of the crank rotation I do not need to apply any pressure with my holding arm. This is just a technique for using minimal effort to grind. If I did not do this adjustment then I would use slightly more effort when cranking and the machine might move once or twice while doing a full 36g grind. Again, this is a non issue. Summary--- I love it. I really enjoy using it. It has greatly improved my espresso. I cannot find an issue with the negative points that others raised. It is so much better than my baratza encore for making espresso. It is better than the other hand grinders that I have tried. If you really want a hand grinder and you feel this is the one for you, then I would say buy it :-)
