Soluble coffee is a dried soluble powder or liquid coffee extract that can be reconstituted with hot water when desired to produce coffee. Essentially, it consists of coffee solids and oils from brewed coffee that are spray-dried and packaged for convenient preparation. The manufacturing process allows coffee enthusiasts to enjoy coffee anywhere and anytime without access to fresh beans or a coffee maker.

Soluble coffee was invented in 1930 by an American businessman named George Constant Louis Washington. His goal was to create a shelf-stable version of coffee that soldiers could enjoy in the field during World War II. Since then, soluble coffee has evolved significantly and now comes in many varieties to please different tastes.

How is Instant Coffee Made?

The process to make soluble Instant Coffee starts by brewing high-quality green coffee beans to produce regular coffee liquor. Then, the water is removed using one of two primary techniques - spray drying or freeze drying.

In spray drying, the hot coffee liquid is sprayed into a chamber of hot air, which causes it to dry into powdered form almost instantly. This process retains more of the coffee's original oils.

In freeze drying, the coffee is frozen and placed under low pressure, allowing the ice to transition directly from solid to gas without forming liquid water in between. This slow process protects the soluble solids but loses more of the flavor oils. As a result, freeze-dried coffee has a cleaner taste.

Once dried, the powdered coffee extract is milled to the desired particle size and packaged for retail distribution and consumption. Additional flavors are sometimes added during production as well.
