The Evolution of Commercial Coffee Machines: From Steam to E61

Ever wondered how today’s sleek, high-pressure espresso machines evolved from 19th-century contraptions that barely resembled modern brewers? The journey from steam-driven extraction theories to the precise, temperature-stable machines we rely on today is a fascinating tale of innovation, trial, and error spanning over a century.

From 1818 to the 1960s, commercial coffee machines transformed dramatically: 12 key patents and inventions between 1818–1900 laid early foundations, 1901–1947 introduced single-serving pressurized brewing, 1948–1961 brought lever-driven crema, and 1962 onward revolutionized thermal stability with models like the E61.

The Birth of Coffee Extraction: Pre-1900 Experiments

Long before espresso machines resembled the ones we know, 19th-century inventors were obsessed with using steam and pressure to extract coffee. Their goal? A perfect brew extracted solely through vapor power.

• 1818: Romershausen (Prussia) patented an “extractor.”
• 1822: Louis Bernard Rabout (France) refined the idea using blotting paper to clarify the brew.
• 1824: Paris craftsman Caseneuve designed an overly complex device to preserve aroma.
• 1827: Laurens (France) emphasized pre-wetting coffee grounds with steam before extraction.
• 1833: Samuel Parker (UK) used a pump to push water upward through coffee—opposite to conventional gravity flow. He noted bitterness appeared later in the brew.
• 1838: Leburn (Paris optician) created small tabletop coffee makers popular in Southern Europe.
• 1840: Tiesset employed a vacuum pump to drive hot water through coffee with extra force.
• 1844: Cordier (France) sketched multiple brewers, one resembling a 1874 German design by Eicke.
• 1847: Romershausen built a steam pressure coffee pot.
• 1855: Loysel (France) introduced a 4.5-meter-tall bar coffee machine claiming 10,000 cups/day output.
• 1868: Reiss (Vienna) developed the “Vienna pot.”
• 1885: Angelo Moriondo (Italy) patented a machine making 50 cups at once.

The Early Era: 1901–1947, The Rise of Single-Serve Brewing

The 20th century kicked off with a breakthrough: the ability to brew one cup of espresso at a time under pressure. This period gave birth to the foundational technology still used in modern machines.

• 1901: Luigi Bezzera patented a coffee machine design.
• 1902: 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 trouble.
• 1905: La Pavoni company was officially founded.
• 1906: Arduino patented a machine with a heat exchanger for rapid water heating.
• 1909: Luigi Giarlotto introduced a pump to solve insufficient extraction pressure.
• 1910: Giarlotto’s second patent featured a screw-down piston to fully express coffee flavors.
• 1935: Illy Doctor invented an air-compression machine pushing water through coffee.
• 1938: Boilers transitioned from vertical to horizontal placement for better performance.

The Golden Age: 1948–1961, Pressure, Temperature & Crema

This era saw the emergence of the beloved crema and machines that could handle higher pressure with less manual effort, forever changing the espresso experience.

• 1948: Gaggia launched the piston-style lever and spring coffee machine, popularizing high-pressure brewing.
• 1952: Large vertical espresso machines rapidly fell out of favor.
• 1956: Cimbali introduced hydraulic systems to reduce the physical effort of lever operation.

The Modern Foundation: 1962 Onward, Thermal Stability & Electronics

With electronics and advanced engineering, commercial coffee machines became more consistent, efficient, and capable of maintaining ideal brewing temperatures throughout long service periods.

• 1955: Giampietro Saccani made strides in stabilizing brew head temperatures.
• 1961: The E61 machine, a Italy-Spain collaboration, revolutionized brewing by pre-pressurizing water before heating it—shifting from the older method of pressurizing hot water. This design became a milestone in thermal control and consistency.

Frequently Asked Questions

What was the first patented coffee extraction device?

The first patented coffee extraction device was by Romershausen in Prussia in 1818. It was an “extractor” patent, marking one of the earliest attempts to mechanize coffee brewing.

When did commercial single-serve espresso machines appear?

Single-serve espresso machines emerged in 1901 with Luigi Bezzera’s patented design, which was later commercialized by Desiderio Pavoni starting in 1902, with the La Pavoni company founded in 1905.

What was the significance of the 1948 Gaggia machine?

The 1948 Gaggia machine introduced the piston-style lever and spring system, enabling high-pressure brewing and leading to the creation of crema, which became a defining feature of modern espresso.

How did the E61 machine improve coffee brewing?

The 1961 E61 machine revolutionized brewing by pre-pressurizing water before heating it, rather than pressurizing hot water. This design greatly improved temperature stability and brewing consistency.

What role did boiler orientation play in early machines?

Boiler orientation shifted from vertical to horizontal in 1938, improving machine performance and ease of maintenance, marking a key development in early espresso machine design.

Who contributed to early pressure-based coffee extraction innovations?

Key contributors included Luigi Bezzera, Desiderio Pavoni, Giarlotto, and Illy, who between 1901 and 1935 developed pumps, pistons, and air compression systems to improve extraction under pressure.
