Description
Maximum flavour, minimum complexity. Preselection functions allow the user to define their own personal aroma preferences, so one touch of a button is all it takes to prepare the perfect cup of coffee. It couldn’t be easier.
Freshly ground, not capsuled
The defining features of the Professional Aroma Grinder include 12.2%* more aroma and consistently high grind quality over its entire service life. Combined with the eighth-generation brewing unit and the 3D brewing process, the result in the cup is truly sublime coffee. The E4 prepares double products in two cycles. This results in maximum aroma, because the user can take advantage of the variable brewing unit’s full range of 5 to 16 grams of ground coffee for both cups.
Hot water in no time
Fancy a cup of tea for a change? No problem. Simply turn the switch to start hot water preparation and up to 300 ml of hot water will flow into the cup in no time at all.
Harmonious design
The E4 reflects the characteristic design of JURA coffee machines, with clean lines and surfaces. Crafted with maximum precision, the minimalist lines emphasise the premium quality of the machine. The use of colours follows the same minimalist approach. While the complete body of the machine is in understated Piano Black, chrome-plated details add accents and set off the finished coffee to perfection.
Changing the filter
Thanks to the integrated RFID (Radio-Frequency-Identification) chip, the CLARIS Smart continuously records information about filter use and alerts the user when the filter capacity has been used up. CLARIS Smart is automatically detected by the coffee machine and water is automatically routed through it.
Descaling the machine
Scale is the biggest enemy of any appliance that uses water. Only use JURA descaling tablets, which remove scale gently to extend the life of your coffee machine.
Cleaning the machine
Cleaning extends the life of your coffee machine and keeps the coffee quality at the highest level. Only use JURA cleaning tablets, which are specially designed to work with the cleaning program.
