Rancilio Specialty RS1 has passed Specialty Coffee Association tests and is now an SCA certified espresso machine.
The quantitative temperature tests were carried out on several simultaneously operating groups. In a series of dispensing runs at different temperatures (between 90.5°C and 96°C), the RS1 achieved high thermal stability, with an average oscillation of ± 0.6°C, well below the SCA value of 1.1°C required to pass the test.
In the temperature control response time test, the RS1 achieved delivery temperature stability within the required time interval (10 minutes), being highly responsive from a thermodynamic perspective.
In the quantitative pressure test results, the RS1 espresso machine operated reliably, without pressure fluctuations (Δ ≤ 0.4 bar). This included simultaneous dispensing from several groups.
Two different baskets were used for the extraction tests. The results met the required standards with an output extraction yield close to 20 per cent.
