How the Espresso Machine Was Invented

Ever wonder how espresso went from a slow, low-pressure drip to the bold shot pulled in 30 seconds under nine bars of pressure? The journey began in early 20th-century Italy, where inventors and roasters relentlessly pursued a better way to brew coffee—fast, intense, and full of crema. That quest led to the world’s first true espresso machine, designed not for home use but for busy cafés.

The first commercial espresso machine was invented in 1903 by Italian engineer Luigi Bezzera. In 1905, Desiderio Pavoni bought the patent, improved the design—fixing issues with low pressure and high temperature—and began selling espresso machines to cafés. Optimal brewing was later found to occur at 9 bars of pressure and 90°C water temperature.

The Birth of the Espresso Machine

In 1903, Italian industrialist Luigi Bezzera invented the first machine capable of producing espresso commercially. This wasn’t just a drip brewer—it used steam and pressure to extract coffee much faster than traditional methods. His goal was simple: speed up service in busy cafés.

However, Bezzera’s original design had flaws. The pressure was often too low and the temperature too high, resulting in bitter, poorly extracted coffee. That’s where Desiderio Pavoni stepped in.

Pavoni’s Commercial Breakthrough

In 1905, Pavoni acquired Bezzera’s patent and began refining the technology. He improved the machine’s ability to handle pressure and heat, making it more practical and pleasant for café use. Pavoni then started manufacturing and promoting the machines, bringing espresso brewing to a broader commercial audience.

These early espresso machines remained largely unchanged in design and function until 1935. During that time, they dominated Italian cafés but were still limited by inconsistent temperature and pressure control.

Technological Stagnation and the Illy Innovation

From 1905 to 1935, no significant technical advancements were made to the espresso machine. The basic design and brewing process remained primitive by modern standards. Then, in the mid-20th century, Francesco Illy, founder of the Illycaffè company, introduced new engineering concepts that pushed espresso technology forward.

Though not detailed in the original text, Illy’s contributions marked a turning point toward more precise and controlled espresso brewing, setting the stage for the modern espresso machine.

The Science of the Perfect Espresso Shot

Italian coffee professionals didn’t stop at invention—they conducted countless experiments to perfect the espresso formula. Through trial and error, they discovered the optimal brewing parameters that produce the best-tasting shot.

The key findings? The ideal espresso is brewed at 9 bars of pressure and a water temperature of 90°C. These settings extract the right balance of flavours, aromas, and crema—without over-extracting bitterness or under-extracting acidity.

Frequently Asked Questions

Who invented the first espresso machine?

The first commercial espresso machine was invented in 1903 by Italian engineer Luigi Bezzera. His design used pressure to brew coffee faster, aiming to serve customers more quickly in busy cafés.

What did Pavoni do for the espresso machine?

In 1905, Desiderio Pavoni purchased Bezzera’s patent and improved the machine by fixing its issues with low pressure and high temperature. He began producing and selling refined espresso machines to cafés, making espresso brewing more practical for commercial use.

When did espresso machines stop improving technologically?

Espresso machines remained largely unchanged in design and function from 1905 until 1935. No major technological advancements were made during that 30-year period.

What are the optimal brewing conditions for espresso?

Italian experiments found that the best espresso is brewed at 9 bars of pressure and 90°C water temperature. These settings help achieve ideal extraction balance, producing good flavour, aroma, and crema.

What happened after 1935 in espresso machine development?

After 1935, Francesco Illy of Illycaffè contributed new engineering approaches that advanced espresso machine technology beyond the stagnant period of 1905–1935, paving the way for modern espresso equipment.
