Rancilio Specialty machines were crafted to let baristas access higher control over their espresso extraction. The RS1 offers full customization over a variety of extraction metrics, including time, temperature, pressure, and volume. While you can program these directly into the machine, the RS1 also features Self-Learning Mode.
In Self-Learning Mode, the RS1 will remember recipe parameters from a shot you pull manually for future use. The machine will record the time, volume, and flow meter pulses of that espresso, as well as any pre- or post-infusion you have manually added.
Afterwards, you can make slight adjustments to the recipe if needed as well as save it on the machine for future use.
