Key Technologies: Coffee pleasure – freshly ground, not capsuled.
The ultimate cup of coffee from fresh beans, freshly ground at the touch of a button, freshly extracted, all in less than 60 seconds – exactly according to your personal taste.
How a JURA automatic coffee machine works
It makes the perfect speciality coffee at the touch of a button – freshly ground, not capsuled. But what happens after you tell the machine to start preparing your speciality coffee? Follow the preparation process with a look inside a JURA coffee machine: from freshly grinding the beans to brewing and the finished result. See how the different technologies work ingeniously together to create the ultimate coffee experience.
The Product Recognising Grinder (P.R.G.)
To ensure the optimum grind for every speciality, JURA engineers developed the Product Recognising Grinder (P.R.G.). The electronically controlled high-performance grinder adjusts in a fraction of a second to the predefined consistency of grind – much more quickly than could be done manually. Its spectrum ranges from very fine for short classics to very coarse for long specialities.
The different brewing processes
The ideal extraction time is crucial to achieving an optimum result. The contact time between the water and the ground coffee needs to be long enough to extract the aroma compounds from the coffee but short enough to avoid removing the bitter substances and tannins.
That’s why, in addition to the standard brewing process, JURA has developed the Pulse Extraction Process (P.E.P.®) for short specialities like ristretto or espresso and the One-Touch Lungo function for long specialities. For the preparation of cold brew specialities using the espresso method, there is also the cold extraction process.
The Intelligent Water System (I.W.S.) with the CLARIS Smart filter cartridge
Coffee contains 98% water. So fresh, cold water is essential to making the perfect cup of coffee. Heating water causes limescale contained in the water to form deposits. JURA has a smart solution: the CLARIS filter cartridge.
- It protects the machine against calcium deposits and extends its service life.
- The machine does not need to be descaled.
- This ensures a consistent high level of quality for both the water and the coffee.
- The Intelligent Water System (I.W.S.) automatically detects when a filter has been inserted.
The milk system
Speciality coffees such as cappuccino and latte macchiato are finished with milk or milk foam. JURA’s innovative milk foam frothers use revolutionary fine foam technology to create a finely textured milk foam with a long-lasting consistency or to simply heat the milk to the desired temperature.
