The Long History of the Espresso Machine

In the 19th century, coffee was big business in Europe. As inventors sought to improve brews and reduce brewing time, the espresso was born

Each topic we tackle on Design Decoded is explored through a multi-part series of interlocking posts that will, we hope, offer a new lens for viewing the familiar. This is the second installment in a series about that centuries-old molten brew that can get you out of bed or fuel a revolution. Java, joe, café, drip, mud, idea juice, whatever you call it, coffee by any other name still tastes as bitter. Or does it? In our ongoing effort to unlock the ways design factors into the world around us, Design Decoded is looking into all things coffee. Read Part 1 on reinventing the coffee shop.

For many coffee drinkers, espresso is coffee. It is the purest distillation of the coffee bean, the literal essence of a bean. In another sense, it is also the first instant coffee. Before espresso, it could take up to five minutes –five minutes!– for a cup of coffee to brew. But what exactly is espresso and how did it come to dominate our morning routines? Although many people are familiar with espresso these days thanks to the Starbucksification of the world, there is often still some confusion over what it actually is – largely due to “espresso roasts” available on supermarket shelves everywhere. First, and most importantly, espresso is not a roasting method. It is neither a bean nor a blend. It is a method of preparation. More specifically, it is a preparation method in which highly-pressurized hot water is forced over coffee grounds to produce a very concentrated coffee drink with a deep, robust flavor. While there is no standardized process for pulling a shot of espresso, Italian coffeemaker Illy’s definition of the authentic espresso seems as good a measure as any:

For those of you who, like me, are more than a few years out of science class, nine atmospheres of pressure is the equivalent to nine times the amount of pressure normally exerted by the earth’s atmosphere. As you might be able to tell from the precision of Illy’s description, good espresso is good chemistry. It’s all about precision and consistency and finding the perfect balance between grind, temperature, and pressure. Espresso happens at the molecular level. This is why technology has been such an important part of the historical development of espresso and a key to the ongoing search for the perfect shot. While espresso was never designed per se, the machines –or Macchina– that make our cappuccinos and lattes have a history that stretches back more than a century.

In the 19th century, coffee was a huge business in Europe with cafes flourishing across the continent. But coffee brewing was a slow process and, as is still the case today, customers often had to wait for their brew. Seeing an opportunity, inventors across Europe began to explore ways of using steam machines to reduce brewing time – this was, after all, the age of steam. Though there were surely innumerable patents and prototypes, the invention of the machine and the method that would lead to espresso is usually attributed to Angelo Moriondo of Turin, Italy, who was granted a patent in 1884 for “new steam machinery for the economic and instantaneous confection of coffee beverage.” The machine consisted of a large boiler, heated to 1.5 bars of pressure, that pushed water through a large bed of coffee grounds on demand, with a second boiler producing steam that would flash the bed of coffee and complete the brew. Though Moriondo’s invention was the first coffee machine to use both water and steam, it was purely a bulk brewer created for the Turin General Exposition. Not much more is known about Moriondo, due in large part to what we might think of today as a branding failure. There were never any “Moriondo” machines, there are no verifiable machines still in existence, and there aren’t even photographs of his work. With the exception of his patent, Moriondo has been largely lost to history. The two men who would improve on Morinodo’s design to produce a single serving espresso would not make that same mistake.
