WARNING: Risk of burns. Do not try to create as much pressure as you can. The aim is great espresso - not maximum pressure, STOP if it's a struggle to pull the arms down. The coffee might be too fine or tamped too densely. The water must be able to pass through the coffee in the portafilter.

Top 3 tips - experiment, experiment and experiment! Remember the ROK is the antithesis of an electronically programmed machine. You are in control. You are the 'settings' - part of the pleasure is making the coffee - the other part is enjoying the result. Good luck - and keep experimenting as the ROK will grow with you ...... These tips should help ......

-

Make sure you use clean fresh water that has not been re-boiled.

-

For the best results make sure the coffee is fresh. Grinding your own beans is best.

-

It is the coffee itself that creates the back-pressure, so ......

-

Use coffee grounds suitable for Espresso. Not too coarse or the water will pass through too easily, you won't feel much pressure in the arms and the coffee will be weak and thin. Not too fine or it will be very hard to push the arms down.  WARNING: Risk of burns. Do not create so much pressure that it becomes too hard to pull the arms down.

-

Tamp down the grounds (about 16g) firmly with the ROK spoon tamper. A good tip is to build the coffee up in small layers, pressing each layer down firmly as you go.

-

How you tamp is as important as the coffee itself - if you don't tamp firmly enough there will not be enough density to create back-pressure; if you tamp too tightly the water may struggle to pass through.

-

An expert tip is to warm the portafilter before you put the coffee in.

-

After filling the ROK with hot water raise the arms then lower a little just until you feel a push-back; then let the water infuse into the grinds for a few seconds.

-

Now lift the arms and then pull them down firmly all the way. An extraction should take between 20 and 30 seconds. You choose!

-

For maximum crema, try overfilling the cylinder with hot water to increase the pressure.  WARNING: Risk of burns. Do not create so much pressure that it becomes too hard to pull the arms down.

-

Push the handles downwards in a firm, smooth motion and hold them at the end of the stroke (curl your fingers around the base legs) until all the water has been extracted.

-

It's a good idea to squeeze the arms down a second time for more crema.

-

Catch the remainder in a second cup and throw this away.

If the arms are too hard to pull down, STOP. The coffee might be too fine or tamped too densely.

To clean your ROK, simply remove the portafilter by turning to the right, knock out the coffee ‘cake’ into a bin and rinse off any remaining coffee grounds that may be left on the body. Occasionally wash with soapy water but do not put the ROK through a dishwasher. The salts will destroy the high quality finish. The milk frother, however, is dishwasher safe.

Occasionally, you may want to maintain your ROK more thoroughly. You can do this in 2 ways -

With the portafilter removed and the ROK upside down, press the centre of the round rubber diaphragm (with the small holes). You will see that this diaphragm deforms allowing you to remove it from the edge. Clean the diaphragm with warm soapy water and dry thoroughly before replacing it, and also clean and dry the inside of ROK from the underside. Replace the diaphragm before usage.

Undo the double top bolt which attaches the plunger to the metal arms. With the bolts off the arms will fold back allowing you to remove the plunger and water cylinder. Clean thoroughly with warm soapy water, dry thoroughy and re-assemble.

To clean the portafilter, remove the inner basket (taking care not to lose the metal ring which keeps it in place) and rinse under running water.

This depends a lot on how firmly you press the arms down. In normal usage expect between 5 to 10 bar

Pre-warm the portafilter - put it in a cup of boiled water for a few minutes (make sure the ROK body is warm and not out of a cold cupboard etc).

Warm up your cups with some hot water before you use them also.

After some time there may be a build up of oily coffee residues on the surface of the bayonet mechanism. This can be solved by cleaning the surfaces with a cloth soaked in warm soapy water. Follow the instructions in 'How do I clean my ROK' paying special attention to cleaning the area where the chrome portafilter attaches.

The coffee grind should be specifically for making espressos. The grind should be fine. If it’s coarse, the water will pass through too easily so it won’t create enough pressure. If it's too fine it might be too dense and create too much resistance.
