Rancilio is an espresso machine manufacturer, founded in 1927 by Roberto Rancilio in Parabiago, Milan, Italy. Rancilio would become best known for its innovative distribution networks, effective use of industrial design and reputable reliability.
Rancilio's earliest well-known machine was 'La Regina' – a vertical boiler machine, similar to the original Bezzera and Victoria Arduino devices in function and gilded 'Belle Epoque' styling.
In 1950, Rancilio released a horizontal boiler machine, the Invicta Horizzontal, showing evidence of the postwar shift toward spare, modern styling. The machine however, still used the same forced-steam brewing method from the early 20th century. By 1953, Rancilio adopted lever piston technology introduced by Gaggia. In 1957, Rancilio released a model which automated the lever process, the H/L Automatica. The company followed new technological trends towards continuous deliver brewing introduced by Faema in 1961. In the 1965, Rancilio commissioned design work from industrial designer Marco Zanuso, beginning with the Rancilio Z8, and continuing with the Z9 in 1974. Rancilio continued with several Z-series machines, with the Z11 being the last. The S-series machine would become popular in the 1990s, and become well known in the North American marketplace. 
In 2001, Rancilio revamped their lineup, introducing the basic Epoca, and the Classe series. In 2011, they introduced a new advanced brewing system for the Classe 9 called Xcelsius, which gives precise control of water temperature during the brewing cycle. This allows for "temperature profiling" where the temperature of the water can be raised or lowered a few degrees during the brew cycle to change the flavor of the extraction.
Rancilio made an attempt at a superautomatic machine, the Classe 12, and used cafes in Borders bookstores as a test market. It was deemed a failure, recalled, and abandoned. They subsequently purchased the Swiss Egro brand of superautomatic machines and have built a presence in that market with their successful Egro One.
For the home market, they produce the Silvia machine: a one group machine with a vibratory pump and a single boiler for both steam and hot water. It is frequently sold with its companion Rocky grinder. These have gained a following among enthusiasts for home use.
The company Rancilio has now been sold to Ali group (an investment fund).
