The Evolution of Commercial Coffee Machines from 1818 to Today

Ever wondered how today’s espresso machines evolved from early steam-powered contraptions? The path from 19th-century patent filings to modern, temperature-stable brewers is longer—and more inventive—than you might think. This timeline reveals every major leap in commercial coffee extraction technology.

In short: Commercial coffee machines have been evolving since 1818, when Dr. Romershausen patented a coffee extractor in Prussia. Over the next 150 years, key innovations—including piston-driven pressure (1901), heat exchange systems (1961), and stable brew temperatures—defined the espresso machines we use today.

The Brewing Groundwork: Before 1900

Long before espresso became a household term, inventors across Europe were patenting devices aimed at improving coffee extraction. Most focused on using steam to extract flavor—though methods varied wildly in complexity and success.

• 1818: Dr. Romershausen of Prussia patented an “extractor” device.
• 1822: Frenchman Louis Bernard Rabout patented a design using blotting paper principles to achieve a cleaner extraction, building on Romershausen’s concept.
• 1824: Paris craftsman Caseneuve created an overly complex coffee maker designed to preserve aroma, though it was never manufactured.
• 1827: Laurens’ French patent emphasized pre-wetting coffee grounds with steam before extraction.
• 1833: British inventor Samuel Parker’s device pumped water upward through coffee—opposite to conventional downward flow. He noted that bitterness typically appeared later in the brew.
• 1838: Parisian optician Leburn designed several small table-top coffee makers popular in southern Europe.
• 1840: Tiesset employed a vacuum pump to pull hot water downward with extra force through coffee grounds.
• 1844: Frenchman Cordier’s patent included drawings of various coffee brewers, one resembling the German Eicke machine from 30 years later.
• 1847: Romershausen built a steam pressure coffee boiler.
• 1855: Frenchman Loysel introduced a large capacity bar-style coffee machine (around 4.5 meters tall), claiming it could produce 10,000 cups per day.
• 1868: Viennese innovator Reiss developed a new “Vienna pot.”
• 1885: Italian Angelo Moriondo patented a machine capable of making 50 cups at once.

The Birth of Espresso: 1901–1947

This era marked the shift from batch brewing to individual servings, with the first patents for single-cup extraction under pressure.

• 1901: Luigi Bezzera patented a coffee machine design.
• 1902: His friend Desiderio Pavoni added a pressure relief piston and began commercial production.
• 1903: Bezzera sold his patent to Pavoni for 10,000 lire due to financial difficulties.
• 1905: La Pavoni company was officially founded.
• 1906: Italian Arduino patented the inclusion of a heat exchanger to rapidly heat water within the machine.
• 1909: Luigi Giarlotto introduced a pump to solve insufficient pressure during extraction.
• 1910: Giarlotto’s second patent featured a screw-down piston to fully extract coffee flavors.
• 1935: Dr. Illy invented the first machine using compressed air to push water through coffee grounds.
• 1938: Boiler orientation shifted from vertical to horizontal placement, improving function and maintenance.

Pressure and Precision: 1948–1961

The post-war years saw a focus on increasing pressure and refining temperature control, leading to the iconic crema and more consistent extractions.

• 1948: Gaggia launched its piston-style lever and spring coffee machine to the market.
• 1952: Traditional large upright machines rapidly disappeared from the market.
• 1956: Cimbali introduced hydraulic systems to reduce the physical effort needed for lever-operated machines.

The Modern Era Begins: 1962 and Beyond

Advancements in electronics and thermal stability led to the development of machines that could maintain optimal brewing conditions throughout the day.

• 1955: Giampietro Saccani made strides in stabilizing the temperature of the brewing head.
• 1961: The E61 machine, a collaboration between Italian and Spanish engineers, revolutionized the industry by pre-pressurizing water before heating it—rather than the reverse. This model became a lasting standard.

Frequently Asked Questions

What was the first patented coffee extraction device?

The first known patent for a coffee extraction device was granted in 1818 to Dr. Romershausen in Prussia. It was an early “extractor” designed to brew coffee more effectively.

When did espresso machines start making single servings?

Single-serving espresso extraction began in 1901 with Luigi Bezzera’s patented machine, which was later commercialized by Desiderio Pavoni starting in 1902.

What was the significance of the 1961 E61 machine?

The E61 machine, developed in 1961, was revolutionary because it pre-pressurized water before heating it, ensuring better temperature stability and extraction consistency—a major improvement over earlier designs.

How did boiler orientation change espresso machines?

In 1938, boilers in espresso machines were reoriented from a vertical to a horizontal position, which improved both machine performance and ease of maintenance.

Who introduced the first lever-driven espresso machine?

Gaggia introduced the first lever-driven piston and spring espresso machine in 1948, which allowed for higher pressure extraction and the creation of crema.

What role did the heat exchanger play in coffee machines?

The heat exchanger, patented by Arduino in 1906, allowed for rapid heating of water inside the machine, improving efficiency and helping maintain brewing temperature.
