Every espresso machine on the market today, from a $449 entry-level Gaggia to a $6,600 La Marzocco, descends from a chain of specific patents filed over roughly sixty years by a small handful of Italian inventors solving the same basic problem: how to force hot water through finely ground coffee fast enough to make it commercially practical, without ruining the flavor in the process.
1884: A Forgotten Patent in Turin
The first known patent for an espresso-style machine belongs to Angelo Moriondo, a hotelier and inventor from Turin, who registered Patent No. 33/256 in June 1884 for what the filing called "new steam machinery for the economic and instantaneous confection of coffee beverage." Moriondo's machine used a combination of steam and boiling water pressure to brew coffee quickly for the bars he owned, and it won a bronze medal at the 1884 Turin General Expo. He built only a handful of the machines, used exclusively in his own establishments, and the design never reached wider production, leaving Moriondo a genuine footnote rather than the household name later inventors became.
1901: Bezzera's Patent and the Multi-Group Machine
Milanese manufacturer Luigi Bezzera filed the next major patent in 1901, describing a machine with a central boiler feeding multiple brewing "groups," letting a single machine pull several shots at once for a busy bar. Bezzera's design still relied on steam pressure to force water through the grounds, and steam-based extraction, run hot enough to build sufficient pressure, tended to scorch the coffee and pull out excess bitterness along with it. It solved the speed problem the era's coffee bars actually needed solved, even if the flavor still lagged behind what the equipment would eventually be capable of.

1903-1905: La Pavoni and the First Mass-Produced Machine
In 1903, Bezzera sold his patent to Milanese engineer Desiderio Pavoni, who refined the design and founded La Pavoni to manufacture it commercially. In 1905, La Pavoni launched the "Ideale," widely credited as the first mass-produced espresso machine, bringing café-style coffee brewing out of a single inventor's workshop and into bars across Italy for the first time. La Pavoni remains a functioning coffee equipment brand today, more than a century later.
1938: Gaggia's Steamless Breakthrough
The steam-pressure design that Bezzera and Pavoni relied on had a ceiling: it could never fully escape the scorched, bitter edge that high-temperature steam extraction left in the cup. Achille Gaggia broke that ceiling on September 5, 1938, filing a patent for a machine nicknamed "Lampo" that used hot water pressure instead of steam to push water through the coffee bed. Removing steam from the brewing process itself was the real innovation, and it's the direct ancestor of how every modern espresso machine, from a home semi-automatic to a commercial three-group bar setup, still works today.
“Gaggia's real invention wasn't a faster way to make coffee. It was a way to make coffee under pressure without steam wrecking the flavor on the way through.”
1947: The Lever, the Spring, and the Birth of Crema
Gaggia filed a second, equally important patent in 1947 for a lever-operated piston mechanism built around a spring, letting a barista manually pull a lever to drive a piston down through a cylinder of pressurized water and coffee. That mechanical, spring-assisted pressure was high and consistent enough to produce something earlier machines never reliably had: crema, the reddish-brown foam layer that forms on top of a well-pulled shot from emulsified coffee oils and carbon dioxide. Gaggia marketed the resulting drink as "caffè crema," and the lever machine became the design that defined professional espresso for the next several decades, right up until electric pumps eventually took over the same basic job.
From Lever to Pump: The Postwar Shift
Manual lever machines demanded real physical technique, a consistent pull on a spring-loaded arm, timed and weighted correctly shot after shot, which made quality heavily dependent on the individual barista's skill and stamina over a long shift. Electric pump-driven machines, which became commercially practical through the 1960s and 1970s, replaced the barista's arm with a motorized pump capable of producing the same roughly 9 bars of pressure automatically and consistently, shot after shot, without fatigue. That shift is why the overwhelming majority of machines sold today, semi-automatic and super-automatic alike, use an electric pump rather than a lever, even though a small dedicated market for manual lever machines, covered in our best manual lever espresso machines guide, has never fully disappeared.
What Hasn't Actually Changed
Strip away a century and a half of engineering refinement, and the core mechanism Moriondo, Bezzera, Pavoni and Gaggia were all chasing is the same one every machine on the market still runs: hot water, forced through finely ground coffee, under enough pressure to extract quickly instead of steeping slowly. Everything since, PID temperature control, pressure profiling, built-in grinders, has refined that mechanism rather than replaced it. Our science of espresso extraction guide covers how those refinements translate into the variables you actually control at home today.
