Rancilio - Specialty RS1 - Black - 2 Group Heads

The RS1 helps coffee professionals offer a better coffee experience by providing cutting-edge brewing technology combined with Rancilio expertise and a unique workflow design, resulting in an easy to use espresso machine with a great value. Rancilio Specialty RS1 passed the rigorous Specialty Coffee Association testing standards and is recognised as a SCA Certified Espresso Machine. Each stainless steel group contains a micro-boiler and two heating elements. As well as keeping the temperatures of both the water and the group stable, the multi-boiler system improves the thermal performance of the machine, even when simultaneously brewing espresso and steaming milk, and allows different temperatures to be set for each group head. Thanks to Advanced Temperature Profiling technology, baristas can increase or decrease the temperature of the water dispensed during espresso extraction by up to 5°C (9°F). By accurately controlling the temperature profile of the espresso extraction, baristas are given a precise tool to unlock the flavour potential of each single-origin coffee or blend. By adjusting the temperature, variable results can be achieved in terms of sweetness, acidity, body, bitterness and astringency. The barista can vary the water pressure both in the initial stage (pre-infusion) and in the final stage (post-infusion) of the extraction process, choosing between mains pressure or pump pressure, and adjust the duration of both stages. By using low-pressure water from the mains, the barista can achieve more consistent extractions, reducing the risk of channelling and better preserving soluble substances and aromas which, with high-pressure over-extraction, may not make it into the cup.
