Hands-On Review & Editor's Verdict
Overview: The Rocket Appartamento is an icon in the prosumer espresso world. Hand-built by master Italian craftsmen in Milan, the Appartamento strips away unnecessary digital clutter to deliver pure, commercial-grade espresso mechanics in a compact chassis designed for home kitchens.
At its core sits the legendary E61 brew group—a 9-pound solid brass casting that circulates hot water continuously from the 1.8-liter copper boiler. This thermosiphon system ensures unwavering thermal stability, while the heat-exchange design enables simultaneous brewing and high-pressure milk steaming for silky, café-quality cappuccinos and flat whites.

Frequently Asked Questions
What makes the E61 group head so popular among espresso connoisseurs?
▾
The massive 9-pound brass E61 group maintains constant thermal mass, preventing temperature dips when brewing. It also features a mechanical pre-infusion chamber that gently saturates coffee grounds before ramping to full 9-bar pressure.
Can the Rocket Appartamento steam milk while brewing an espresso shot?
▾
Yes. Because it uses a heat-exchange (HX) boiler system, steam is drawn directly from the main boiler while fresh water is heated on-demand through an internal tube for brewing, allowing simultaneous operation.
How long does it take for the machine to heat up from cold?
▾
While the boiler reaches pressure in about 8 minutes, allowing 20 minutes ensures the heavy brass E61 group head and portafilter are thoroughly heat-soaked for ideal extraction temperature.
