How Coffee Became Quick

The invention of espresso:

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. …

In [Luigi] Bezzera’s original patent, a large boiler with built-in burner chambers filled with water was heated until it pushed water and steam through a tamped puck of ground coffee. The mechanism through which the heated water passed also functioned as heat radiators, lowering the temperature of the water from 250°F in the boiler to the ideal brewing temperature of approximately 195°F (90°C). Et voila, espresso. For the first time, a cup of coffee was brewed to order in a matter of seconds.
