What are the shipping costs?
In Europe and the UK you don’t pay any shipment costs. Outside Europe the shipping costs will be €100,00. For Turkey and Switzerland it is €50.
What materials are used in the Superkop?
The housing is molded from aluminum, the internal mechanism / moving parts are stainless steel parts, made by molding or CNC parts. The product has been designed to ‘last forever’, making it a real tool for life.
Will it be possible to adapt the pressure applied and or duration of extraction?
Yes, it is possible to adapt the pressure and the duration of the extraction because you do it yourself.
Longevity: which parts do we expect to be replaced – are there any seals? Do we plan to offer replacement parts and which?
Testers have been using the Superkop for the past two years now and have not required any replacements so far. We expect replacements for the seals and gas spring in 5 years time, costing approximately ca.15 euro
Is the coffee puck compatible to other standard sizes?
Yes, you receive one basket for a double espresso, 18 to 20 gr. and the tamper size is 58mm
Thermodynamics: other products with a similar approach need a warm-up run
(e.g. boiling water only) to get the brewing chamber up to temperature – would we recommend this too for SUPERKOP to ensure the desired brewing temperature of 92 -96°C? You do not have to warm up the Superkop because you pour boiling water into the food safe polycarbonate isolated water cup.
Does Superkop use a spring?
You press the lever down with manual power. It is very easy to do because there is a transfer of 1:40. A gas spring is used to return the piston.
Do I receive the stand-alone version or the wall version?
When ordering you will receive a stand-alone version. With an easy installation guide you will be able to use the wooden stand. Should you wish to convert to the wall version at a later date you can buy the wall accessory when needed.
How do you prevent the water cup from breaking at high pressure?
To prevent the water cup from breaking, we have installed an overpressure valve that opens at 20 bar. To make a good espresso you need 9-11 bar.
Why does it take 6 pumps downward for one espresso? Why not one big pull per shot, like a traditional machine?
Our system builds up the correct pressure in every pump. It takes 6 pumps. It is fully manual. If you would put the complete pressure in one big pull the arm of the lever must be very long; too long. The 6 pulls are not uncomfortable and allow you to apply the correct extraction time of around 25 seconds very naturally. The way to regulate the pressure is the speed of the pumps and thus the complete extraction process combined with the volume and grain of the beans.
