Who's The ROK Suitable For
As I’ve mentioned just now, like all manual coffee grinders, the ROK Espresso Coffee Grinder is great for those who want to get the full barista experience, and grind their own coffee beans at home. This product is ideal because it requires little effort and time, and can produce results at the fine – mid settings similar to electric burr grinders at the $600 range. Of course, this all comes at a higher price, it’s significantly more expensive than majority of other hand-held coffee grinders out there – if you’re on a budget, you should check out the upgraded Hario Skerton instead. Otherwise, a coffee grinder is a lifelong investment, if you are an Espresso lover who have some spare money to spare, then I recommend the ROK Espresso Coffee Grinder to you.
Main Features of The ROK Coffee Grinder
Design & Appearance
The ROK Coffee Grinder doesn’t use traditional cranks sticking out on the side, like other hand-held coffee grinders. It has a long, vertical handle on the side instead, like this:
This ROK Kitchen Tool’s coffee grinder is constructed using stainless steel aluminum, a vertical crank on the side, and an adjustment wheel that is built to adjust the coffee grinder’s settings. The ROK grinder uses 48mm stainless steel conical burrs and designed to reduce wobble (that causes inconsistent grinds) with its double bearing shaft design.
This is a conical burr grinder that uses 48mm stainless steel burrs. It’s designed with double bearing shafts to reduce wobble during operation. Based on the material and design, I think steel burrs are pretty durable.
Just like all other hand-held coffee grinders, this one is quiet – 75 decibels. If you are grinding your coffee in the morning, you can rest assure that it won’t disturb anyone in the family nor block out any conversations. This didn’t happen to me, but I read from other customer reviews that the coffee grinder sometimes make these squeaky noises – but I read adding some natural lubricant (ie. olive oil) around the hinges fixes the problem.
Ease Of Use
The ROK Espresso Coffee Grinder is very easy to use because it’s designed with human factors and ergonomics in mind. Instead of the traditional, horizontal crank, this grinder’s crank is placed vertically on the side. This makes the grinding process a lot more natural and efficient. With its efficient crank design and double bearing design, the ROK Grinder takes around half the revolutions required by other manual coffee grinders.
For example, a standard coffee grinder takes around 190 revolutions to grind a double shot of Espresso, but this grinder only takes 62! As such, it takes a lot less time to grind coffee.
Accessible Grind Settings
Unlike nearly every other handheld coffee grinders out there, you can adjust the ROK Coffee Grinder’s grind settings with the adjustment wheel on the outside – you don’t have to take anything apart, it’s very straight forward.
Ease of Cleaning
In-order to clean your ROK Espresso Coffee Grinder, we should wash it occasionally with water and soap – but don’t put it in the dishwasher, it will erode the grinder’s high-quality finish. You also need to clean the diaphragm, water cylinder, and plunger using warm, soapy water. Remember, before using it again, you must dry it thoroughly. Lastly, you can clean your portafilter can be cleaned by simply removing it and rinsing it with water.
When I used the grinder, I noticed that there are lots of residual left in the hopper and on top of the adjustment wheel – it creates a little bit of mess that’s quite difficult to clean.
The price of the ROK is quite steep. It’s way more expensive than other hand-held coffee grinders and on par wiht electric grinders. However, it’s still pretty good value for money considering the fact that the grind quality it produces matches high-end coffee grinders. I personally think if you have the spare cash, want to be immersed in the barista experience, and at the same time…put in the minimum effort, then you should go for this grinder.
The ROK Coffee Grinder comes with a 10-year warranty for all metal parts, and 1-year warranty on other parts. If a part becomes defective, all you have to do is send a photo (via email) to customer services, and they’ll send you a replacement part – delivery charges will be handled by the customer though.
The Coffee Barrister’s Verdict [CONCLUSION]
Alternatively, you may also want to get an electric coffee grinder like the Baratza Preciso for roughly the same budget.
As it stands, you’re essentially getting the results of a high-end product, at the mid-range price. The grind consistency is pretty good from the fine espresso grind to medium range, so it’s perfect for those looking for anything from Turkish to Pour Over, but this is probably not suitable for those looking for French Press.
Overall, I would recommend the ROK Coffee Grinder to Espresso lovers who want to immerse themselves in the world of artisan coffee, and at the same time, have some cash to spare.
- Switch between stepped or step less grinding with an easily removable set of washers
