What Is Instant Coffee?

Instant coffee is a popular type of coffee that is made from dried coffee extract. Similar to the way that regular coffee is brewed, the coffee extract for instant coffee is made by brewing ground up coffee beans, but it is more concentrated. After it has been brewed, the water is removed to make dry powder or fragments which dissolve when added to water. 

There are two main ways of manufacturing instant coffee: 

  • Freeze-drying – This method involves freezing the extract and then cutting it into small pieces. These little fragments are then dried at a low temperature under vacuum conditions. 
  • Spray-drying – This method involves spraying coffee extract into hot air. This quickly dries the spray droplets and turns them into small pieces or powder. 

Both of these methods preserve the flavour, aroma, and the quality of the coffee.
