The History of Espresso: From Invention to Modern Day

Espresso is more than just a drink—it’s a cultural phenomenon that has shaped the way millions of people enjoy coffee every day. From the bustling cafes of Milan to the sleek third-wave coffee shops in London, espresso remains the foundation of countless beverages and rituals. But how did this concentrated, crema-topped shot of coffee come to be? The history of espresso is a story of innovation, necessity, and a relentless pursuit of speed and flavour.

In this article, we’ll take you on a journey through time, exploring the key inventions, inventors, and social shifts that turned espresso into the global icon it is today. Whether you’re a home barista or a seasoned professional, understanding the roots of espresso can deepen your appreciation for every cup you brew.

The Birth of Espresso: 19th-Century Innovations

The story of espresso begins in the 19th century, when coffee was already a popular beverage in Europe, but brewing was slow. In 1884, Angelo Moriondo of Turin, Italy, patented the first known espresso machine—a bulky steam-powered device designed to brew coffee quickly by forcing water through coffee grounds. While Moriondo’s invention was a breakthrough, it was Luigi Bezzera who refined the concept in 1901. Bezzera’s machine used steam pressure to push water through coffee, producing a concentrated shot in under 30 seconds. He also introduced the group head, a feature still used today.

Bezzera’s innovation was commercialised by Desiderio Pavoni, who purchased the patent in 1903 and began manufacturing the ‘Ideale’ machine. By 1906, Pavoni was demonstrating his espresso machine at the Milan Fair, where the term ‘espresso’ (meaning ‘expressed’ or ‘pressed out’) was first used. These early machines were large, steam-driven, and prone to overheating, but they laid the groundwork for everything that followed.

The Rise of the Lever Machine: 1930s–1940s

The next major leap came in 1938 when Francesco Illy, founder of illycaffè, invented the Illetta machine. This was the first espresso machine to replace steam with compressed air, allowing for a more consistent pressure and a better-tasting shot. Illy’s system also introduced the use of pressurised water, which helped create the thick, golden crema we now associate with quality espresso.

However, it was Achille Gaggia who truly revolutionised espresso in 1945. Gaggia’s lever-operated machine used a spring-piston mechanism that forced water through coffee at high pressure (around 8–10 bars), producing a rich crema that steam-based machines could not achieve. The lever machine became an instant hit in Italian cafes, and Gaggia’s design is the direct ancestor of most modern espresso machines. His invention also popularised the term ‘caffè crema’ and set a new standard for espresso quality.

• The Gaggia lever machine allowed baristas to control pressure manually, leading to more consistent and flavourful shots.

Post-War Boom and the Espresso Bar Culture

After World War II, espresso became synonymous with Italian social life. The 1950s and 1960s saw a boom in espresso bars across Italy and beyond, as returning soldiers and immigrants brought the culture to the United Kingdom, the United States, and Australia. Machines became smaller, more affordable, and easier to use, with brands like Faema and La Marzocco introducing electric pumps and heat exchangers.

In 1961, the Faema E61 was launched, featuring a rotary pump that delivered consistent pressure without the need for a lever. This machine became the industry standard for commercial espresso, and its design influenced countless models. The E61 also introduced a heat exchanger system, allowing the machine to brew and steam simultaneously—a feature that remains popular in prosumer machines today.

The Third Wave and Modern Espresso

The late 1990s and early 2000s ushered in the ‘third wave’ coffee movement, which emphasised quality, traceability, and craftsmanship. Espresso was no longer just a quick caffeine fix—it became a canvas for showcasing single-origin beans and precise brewing techniques. Baristas began weighing doses, timing shots, and adjusting grind size with scientific rigour. This period also saw the rise of home espresso enthusiasts, thanks to affordable machines like the Rancilio Silvia and the Gaggia Classic.

Today, espresso continues to evolve. Innovations in temperature stability, pressure profiling, and pre-infusion allow baristas to extract nuanced flavours from beans grown in specific regions. At Square Mile Coffee Roasters, we celebrate this heritage by offering carefully curated coffee subscriptions, such as the Prepaid Our Pick Espresso Subscription Fortnightly 12 months - Gift, which delivers exceptional espresso beans straight to your door. For those who prefer decaf, the Prepaid Decaf Espresso Subscription Weekly 3 months ensures you never miss a perfect shot, even without caffeine.

• Modern espresso machines often feature PID controllers for precise temperature management, improving shot consistency.
• Pressure profiling allows baristas to vary pressure during extraction, highlighting different flavour notes.

The Future of Espresso

As we look ahead, the history of espresso is far from over. Sustainability is driving new developments, from energy-efficient machines to compostable coffee pods. Meanwhile, digital technology is enabling remote monitoring and recipe sharing among baristas worldwide. The core principles—pressure, temperature, and grind—remain the same, but our understanding of how to manipulate them continues to deepen.

Whether you’re pulling shots on a vintage lever machine or a modern dual-boiler setup, espresso remains a bridge between tradition and innovation. By exploring its past, we can better appreciate the craft and science that goes into every cup.

From Moriondo’s steam-powered prototype to today’s precision-engineered machines, the history of espresso is a testament to human ingenuity and our love for great coffee. Whether you’re a seasoned barista or a curious beginner, exploring espresso’s rich past can deepen your appreciation for every shot you pull.
