Rocket Espresso has outdone themselves once again! The brand has updated their Giotto and Cellini V2 models to create the Rocket Cellini Premium Plus with PID and the Giotto Premium Plus with PID. These machines still have all the high-end features that were found in the previous models, but they now also include an integrated PID (proportional integral derivative) for a more precise brewing temperature. The folks at Rocket didn’t want to change the sleek, clean lines of the machines (which are handcrafted in Italy) so they have artfully hidden the PID inside each machine’s drip tray.
What are the benefits of having a PID as part of the machine? The PID makes controlling the brewing temperature more efficient, since it considers a variety of factors when calculating the temperature instead of just the pressure, which is what V2 models with just a heat exchanger did, allowing you to get a consistent temperature over and over again. In addition, the PID enables the machine to keep the temperature within one degree of the temperature you have programed in, where as with a typical heat exchanger there is a little bit more variation.
Some of our favorite features on the Rocket Cellini Premium Plus with PID and Giotto Premium Plus with PID that have continued on from the V2 models are the copper insulated heat exchanger boiler, huge water tank and the ever-popular E61 brew group and its thermo syphon system that efficiently heats the brew head. Another nice feature is the anti-burn steam arm, which will prevent your milk from burning and hardening onto the steam arm if you forget to wipe it off right away. However, it is important to remember that this doesn’t mean the steam arm won’t be hot; it will be, so be careful not directly touch the wand after each use.
