While cafe-worthy espresso machines still lie out of the price range for most people, there are more and more affordable versions hitting the market. Still, many models at all price points either create waste from pods and filters or use a lot of energy — or both. In searching for an option that fulfills our love for coffee without creating waste and consuming a lot of electricity, we found ROK. The ROK espresso maker promises a strong, double shot of espresso with zero-waste and zero-energy needed.
After opening the box, we felt pretty intimidated by the machine. It is made from strong, sturdy steel, and is small enough to carry around, but the instructions weren’t incredibly informative. There is also a metal portafilter, which holds the coffee grounds, as well as a plastic coffee scoop that doubles as a tamper, a splitter to turn the double shot into two single shots and a mysterious additional piece that we still do not know its purpose. (If you know, leave us a comment below!)
Luckily for ROK users, the company has an informative YouTube channel, where we found plenty of tutorials as well as helpful tips and tricks to make the best espresso possible. After familiarizing ourselves with the routine, we decided to give it a go.
We added fine coffee grounds to the portafilter and tamped it firmly, but not too firmly, using the back of the coffee scoop. Inserting the portafilter into the machine is probably the trickiest part; we recommend squatting down and looking to see where the notches line up to avoid missing and dumping the grounds everywhere (speaking from experience here).
After the portafilter is secured in place, make sure your mug is lined up at the bottom under the spout, and add boiling hot water to the black plastic rim at the top of the machine. We found about 100 to 110 mL gave us the perfect amount with enough to pull a thin layer of crema at the top of the cup as well.
Pull the arms of the machine up slowly, then push down. If you feel a lot of resistance, don’t push further! The coffee might be tamped in too much, and forcing the arms down could cause the water to burn you. If the arms are moving with just slight pressure, you are doing it correctly. Push slowly, and the water will run through the portafilter and espresso will pour into your mug.
After the arms are all the way down, feel free to pull the arms up and push down one more time to get rid of any excess water and to pull crema. If you want to create two single shots of espresso (a great way to take a quick break with coworkers!), simply attach the clear, plastic splitter to the end of the portafilter after it has been secured into the machine. Place an espresso mug under the end of each side of the splitter, and operate as usual.
After our trial run, we were so surprised at how easy it was to use the ROK espresso maker. We simply composted the used grounds, wiped the machine and portafilter down and it was ready to go for the next round of espresso.
We love it so much, in fact, that we use it multiple times a week. It makes a strong cup of espresso, it is a breeze to use, it is quiet (so we aren’t disturbing the people working around us) and it is quick to clean. It also is small enough to fit on a desk.
Prices vary depending on where you purchase ROK, but it costs about $160-180 USD. The company sells bundles on its website that include the machine as well as a milk frother, coffee and more. Although the plastic parts do feel sturdy, if they happen to break, ROK sells small replacement kits as well, so you can service your machine and get the coffee breaks you deserve for years to come.
