Instant coffee: History, invention, and development of instant coffee
News News blog
Instant coffee revolutionized the way people prepare and enjoy coffee. The convenient powder makes it possible to get a hot cup of coffee in seconds—without complicated brewing processes or special equipment.
The beginnings of instant coffee
Instant coffee was created as early as 1881, when French inventor Alphonse Allais filed the first patent for instant coffee. His invention was given patent number 141520 and laid the foundation for a revolution in coffee preparation.
Nine years later, in 1890, David Strang from Invercargill, New Zealand, developed his own version of soluble coffee. He patented his invention and successfully sold it under the name “Strang's Coffee.” The invention is often mistakenly attributed to Japanese scientist Satori Kato, who was working in Chicago in 1901.
Why was instant coffee invented?
The invention of soluble coffee solved several practical problems of the time:
- Time savings: Conventional coffee preparation was time-consuming and required special knowledge.
- Shelf life: Freshly brewed coffee spoiled quickly, while instant coffee could be stored for months.
- Portability: Soldiers and travelers could finally make coffee quickly anywhere.
- Simplicity: No more complicated brewing methods or expensive equipment were needed.
Nestlé's breakthrough
The Swiss company Nestlé took the decisive step towards industrial mass production in 1938. With its product “Nescafé,” Nestlé established instant coffee as a household standard and made it known worldwide.
Modern manufacturing processes
Today, instant coffee is mainly produced using three processes:
- Spray drying produces fine-powdered instant coffee, which is used especially in cappuccino blends.
- Freeze drying produces higher-quality instant coffee with better aroma retention.
- Vacuum concentration creates liquid coffee concentrates for special applications.
Properties of instant coffee
Instant coffee contains about half the caffeine of regular bean coffee. According to EU guidelines, only roasted coffee beans and water may be used as extraction agents in its production.
The practical invention of soluble coffee over 140 years ago fundamentally changed coffee culture and enables millions of people worldwide to enjoy coffee quickly and easily.
