The Origins of Commercial Semi-Automatic Coffee Machines

Ever wondered how today’s commercial espresso machines evolved from early 19th-century steam experiments? The path from a simple idea—using steam to extract coffee—to the reliable, pressure-driven machines behind your favorite café shot is longer and more experimental than you might think.

The first patent for a coffee extractor appeared in 1818, and by 1961 the E61 machine had revolutionized temperature stability and brewing pressure. Along the way, innovators tested steam soaking, vacuum pumps, and piston levers to perfect the espresso shot.

The Birth of Coffee Extraction Theories (Before 1900)

Long before espresso machines became bar staples, inventors were experimenting with ways to extract coffee using steam and pressure. These early patents laid the groundwork for what would eventually become the modern espresso machine.

• 1818: Romershausen patented an “extractor” in Prussia, one of the earliest known devices aimed at coffee extraction.
• 1822: Frenchman Louis Bernard Rabout improved on this with a design using blotting paper to produce a cleaner brew.
• 1824: Paris craftsman Caseneuve created an overly complex coffee device meant to preserve aroma—though it was never produced.
• 1827: Laurens’ French patent emphasized pre-wetting coffee grounds with steam before extraction.
• 1833: Samuel Parker (UK) introduced a pump system that pushed water upward through coffee—opposite to gravity-fed methods—and observed that bitterness emerged later in the brew.
• 1838: Parisian optician Leburn designed several compact tabletop coffee makers popular in southern Europe.
• 1840: Tiesset developed a vacuum pump to force hot water through coffee with greater intensity.
• 1844: Cordier’s patent included multiple extractor designs, one resembling a machine Eicke would build in Germany 30 years later.
• 1847: Romershausen built a steam pressure coffee pot.
• 1855: Loysel introduced a massive 4.5-meter-tall bar coffee machine claiming to produce 10,000 cups per day.
• 1868: Vienna’s Reiss developed the new “Vienna pot.”
• 1885: Italian Angelo Moriondo patented a machine capable of making 50 cups at once.

The Evolution from Patents to Practical Machines (1901–1947)

The early 20th century saw patents turn into usable, commercial machines. This period gave us the first single-shot espresso makers, laying the foundation for modern café culture.

• 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 issues.
• 1905: La Pavoni company was officially founded.
• 1906: Arduino patented a heat exchanger to rapidly heat water inside the machine.
• 1909: Luigi Giarlotto introduced a pump to resolve insufficient brewing pressure.
• 1910: Giarlotto’s second patent featured a screw-down piston to fully extract coffee flavors.
• 1935: Illy invented the first machine using compressed air to push water through coffee grounds.
• 1938: Boiler orientation shifted from vertical to horizontal placement, improving performance and maintenance.

The Rise of Pressure and the Birth of Crema (1948–1961)

Post-WWII innovations focused on increasing brewing pressure and lowering water temperatures, leading to the iconic crema and more stable extractions.

• 1948: Gaggia launched the piston-lever espresso machine, introducing higher pressure and creating crema.
• 1952: Traditional large vertical machines quickly disappeared from the market.
• 1956: Cimbali adopted hydraulic systems to reduce the physical effort needed for lever-operated machines.

Mature Design and Electronics (1962 Onward)

The modern era of espresso machines began with better temperature control and electronic components. The E61 revolutionized how water was heated and pressurized.

• 1955: Giampietro Saccani contributed to stabilizing brew head temperatures.
• 1961: The E61 machine, a collaboration between Italy and Spain, changed brewing forever. Instead of pressurizing hot water, it first pressurized cold water and then heated it—a major advancement over previous methods.

Frequently Asked Questions

When was the first coffee extraction patent filed?

The first known coffee extraction patent was filed in 1818 by Romershausen in Prussia. It was one of the earliest attempts to create a device specifically for extracting coffee.

What did early coffee machines focus on?

Early machines focused on using steam, pressure, and various filters to extract coffee more cleanly and efficiently. Many prototypes aimed to preserve aroma or improve flavor, often using creative methods like blotting paper or vacuum pumps.

Who made the first commercial espresso machine?

The first commercial espresso machine was developed by Desiderio Pavoni, based on Luigi Bezzera’s 1901 patent. Pavoni began selling machines in 1905 after buying the rights in 1903.

What was the significance of the 1948 Gaggia machine?

Gaggia’s 1948 piston-lever machine introduced high-pressure brewing, which created crema and set the standard for modern espresso extraction.

How did the E61 machine change espresso brewing?

The 1961 E61 machine pioneered heating cold water under pressure, rather than pressurizing pre-heated water. This innovation greatly improved temperature stability and brewing consistency.

Why did vertical boilers disappear after 1952?

Large vertical boilers were bulky and inefficient. By 1952, horizontal boiler designs became standard, offering better performance and easier maintenance.
