The History of La Marzocco Coffee Machines

Ever wondered how today’s sleek, high-performance espresso machines evolved from early 20th-century industrial designs? The story of La Marzocco isn’t just about coffee—it’s about craftsmanship, innovation, and resilience in the face of war, floods, and changing tastes. This is how one Italian company helped define the modern espresso experience.

La Marzocco was founded in 1927 by brothers Giuseppe and Bruno Bambi, who registered the first patent for a horizontal-boiler espresso machine in 1939—ushering in the modern era of multi-group espresso setups. Their GS series, launched in 1970, introduced the now-standard independent dual boiler system, revolutionizing temperature stability and steam control.

The Origins: From Fiorenza to La Marzocco

Giuseppe Bambi, a determined craftsman, partnered with his brother Bruno to create coffee machines independently after producing models like the "Fiorenza" for clients. In 1927, they established Officina Fratelli Bambi, designing, manufacturing, and selling machines with notable success. Giuseppe chose the Marzocco lion—a symbol of Florence—as the company emblem, representing victory and success, and renamed the company La Marzocco.

Design Evolution and the First Horizontal Boiler

As fascism influenced Italian design aesthetics, La Marzocco adapted by refining machine lines while retaining functionality. With rising demand for café espresso, the Bambi brothers focused on reducing machine size and increasing output. On February 25, 1939, Giuseppe Bambi patented the world’s first horizontal-boiler espresso machine, arranging brew groups in a straight line for simultaneous extraction and easier operation.

Post-War Innovation: Lever Machines and the Rise of Pressure

The 1950s saw the rise of lever-operated machines, which used spring-loaded pistons to generate around 10 atmospheres of pressure—creating the iconic espresso crema. This breakthrough transformed espresso flavor profiles and set new standards. Electric gear motors were later added to reduce barista effort. These advancements culminated in the first espresso machines with automated pressure control and electric motors.

The GS Series: A Revolutionary Leap

In 1961, La Marzocco built a new headquarters overlooking Florence. After the devastating 1966 Florence flood, the company faced financial hardship but persevered. By 1970, they launched the GS series—a game-changer featuring independent dual boilers (one for brewing, one for steam) and saturated groups. The GS (short for “saturated group”) maintained optimal brewing temperatures by keeping water constantly circulating through the group head, directly connected to the boiler. This design became a lasting standard in La Marzocco machines.

Global Success and Technological Advancements

The GS series achieved international acclaim, leading to subsequent models like the GS-2, Linea, and FB/70. In 1995, La Marzocco restructured its production, management, and technical support teams, hiring skilled technicians and expanding internationally with a Milan office. Between 2000 and 2008, the brand sponsored the World Barista Championship (WBC), reinforcing its commitment to professional excellence.

Modern Era: PID Control, Pre-Infusion, and New Designs

From 2005 to 2007, La Marzocco released the GB/5, FB/80, and single-group GS/3, all equipped with PID temperature control, digital displays, and multifunction keypads. In late 2008, pre-infusion functionality was reintroduced across standard models, giving baristas greater control over extraction variables. In 2009, the company relocated to a new factory north of Florence with upgraded equipment. That year also saw the launch of the Strada series, featuring pioneering pressure profiling technology developed with input from top baristas. The Vulcano grinder, combining La Marzocco design with Mazzer engineering, debuted in Milan in October 2009 and entered production in fall 2010.

Frequently Asked Questions

When was La Marzocco founded?

La Marzocco was founded in 1927 by brothers Giuseppe and Bruno Bambi, who had previously produced espresso machines under the "Fiorenza" model name.

What was the first major patent by La Marzocco?

In 1939, Giuseppe Bambi registered the world’s first patent for a horizontal-boiler espresso machine, arranging multiple brew groups in a straight line for simultaneous use and simplified operation.

What is the GS series and why is it important?

Launched in 1970, the GS (saturated group) series introduced independent dual boilers—one for steam and hot water, the other for brewing—ensuring stable brewing temperatures. It also featured saturated groups for superior temperature stability, becoming a global standard in espresso machine design.

Did La Marzocco survive the 1966 Florence flood?

Although not directly hit, La Marzocco endured financial challenges after the 1966 Florence flood due to delayed customer payments. The company persisted and launched the GS series in 1970, marking a major turnaround.

What modern features did La Marzocco introduce in the 2000s?

Between 2005 and 2007, La Marzocco released machines like the GB/5, FB/80, and GS/3, all with PID temperature control, digital displays, and multifunction keypads. Pre-infusion was reintroduced in 2008, allowing baristas to refine extraction.

What is pressure profiling in espresso machines?

Pressure profiling refers to controlling the pressure during espresso extraction to influence flavor. The Strada series, launched in 2009–2010, was pioneering in this technology, developed with elite baristas.
