Top innovation: P.E.P.® for espresso and ristretto of outstanding barista quality JURA has perfected the complete brewing process for short speciality coffees. That‘s why the A1 prepares these beverages to the high standard you would expect in a coffee bar. The multi-level AromaG3 grinder ensures that the coffee is optimally ground. It always grinds the beans fresh, quickly yet gently to preserve the aroma. The variable brewing unit has a capacity of 6 to 10 grams and ensures the ideal brewing conditions at all times. The Pulse Extraction Process (P.E.P.®) developed by JURA optimises the extraction time. To make a ristretto or espresso, it forces the hot water through the ground coffee at short intervals. This process allows the flavours of the coffee to fully develop.
