Rancilio

Rancilio is an Italian manufacturer best known for its espresso equipment, founded in 1927 by Roberto Rancilio in Parabiago, Italy, near Milan.

The company produces appliances for commercial and domestic use, especially espresso machines and coffee grinders, which it distributes worldwide.

History

Rancilio's earliest espresso machine was La Regina: a steam-driven vertical boiler model, similar to the original Bezzera, Gaggia, and Victoria Arduino machines in function and gilded Belle Époque styling.[1]

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

Rancilio Silvia

The Rancilio Silvia (officially "Miss Silvia") is a semi-automatic espresso machine manufactured by Rancilio since 1997. James Hoffmann suggests that the Silvia marks the beginning of the "prosumer category" in espresso, representing "miniature commercial machines for the home," and characterizes the Silvia as "the closest to a commercial machine" available among consumer espresso machines.[19] Mark Frauenfelder concurs, noting that the Silvia "shares many characteristics of commercial equipment — robustness and repairability being chief among them."[20] He describes the Silvia as "the most well-documented espresso maker in history, thanks to its legion of hacker fans," and devotes an entire chapter, "Tickling Miss Silvia," to the machine.[20] Hoffmann agrees, observing that the Silvia is "probably the most modified domestic espresso machine in the world."[21] The Silvia is regarded as "an icon in the home coffee market,"[22] "a classic" in the espresso community, and "perhaps the most famous domestic espresso machine on the market," to the point of being recognised as a potential "coffee cliché."[23]

The Silvia placed components of the Audrey into a much heavier steel chassis, finished with a rectangular brushed stainless steel case and drip tray cover, and a cylindrical brushed steel collar covering the brass grouphead. (The Silvia may thus be understood as an example of old wine in a new bottle.) As a result, the Silvia weighs 14 kg, more than 50% more than its ancestor Audrey's 9 kg.[24][17] Hoffmann describes the Silvia as "built like an absolute tank," and exceptionally stable in countertop operation.[25] Matte black rocker switches replaced the translucent orange, fully illuminated switches on prior Miss Rancilio machines, completing the Silvia's visual design.

As the Silvia evolved, online communities began to assign informal version control numbers to denote changes in features relative to production date. (There is no evidence that Rancilio uses or acknowledges these version numbers; they have, however, been employed in peer-reviewed scientific literature.[26]) The initial release of the Silvia subsequently became known as V1.[17]

The production date for each Silvia machine is typically printed as a four-digit code in the bottom-right corner of the manufacturer's sticker concealed beneath the drip tray, or, on some early models, on the bottom of the machine body. The first two digits of this code are the production month, and the second two digits are the production year, such that "0506" would denote a Silvia manufactured in May 2006.[27] The general references for the following version history the Silvia are Avi Schneor's introduction to his SchneorDesign Rancilio Silvia Mega-Mod project[17] and the KaffeeWiki guide to Rancilio Silvia's differences in production series.[24]

V1 (1997-July 2006)

Even within what is generally referred to as the first version of the Silvia, Rancilio did make some alterations. Early V1 machines have a Rancilio logo printed in black on the front of the case; later models have a thick plastic badge attached to the case in the same location. In May 2000, a change was made to the design of the Silvia's boiler, which incidentally accommodates user installation of a PID controller to manage boiler temperature; machines made in April 2000 and earlier have an earlier version of the boiler.[27] In 2002, the boiler design was revised once more, replacing the threaded, replaceable stainless steel heating element with a copper element soldered to the upper half of the boiler.

V2 (August 2006-early 2008)

In August 2006, Rancilio introduced significant changes to the Silvia. The boiler design was revised again, replacing the cast brass connections for steam and water pipes with threaded connections. Rancilio also changed the design of the overpressure valve (OPV) which regulates pressure between the pump and the grouphead. The V1 OPV could only be adjusted to reduce brew pressure by adding washers between the single 20mm nut and the OPV body. The V2 OPV had two 20mm nuts, which could be more easily adjusted to raise and lower brew pressure. The now defunct (but archived) website PIDSilvia described methods both for adding a pressure gauge to the Silvia (among many other useful guides)[28]
