Still drinking instant coffee | The production process of instant coffee that you absolutely don’t know!

Nowadays, boutique coffee has become the mainstream of the market, and instant coffee is quietly disappearing from people's daily lives, but it is undeniable that instant coffee still has a large number of loyal fans, especially our parents' generation, who must have a cup of instant coffee every morning.

We all know that instant coffee is deeply roasted to make the flavor stronger, and its texture is very dry and easy to dissolve. Its taste and quality are far different from freshly roasted coffee, but does anyone really know how instant coffee is made? Instant coffee was invented in 1901, which is more than 100 years ago. I think that from the perspective of respecting history, every coffee lover should know the truth about instant coffee.

First of all, instant coffee is indeed made from coffee. Whole coffee beans are roasted, ground into powder and brewed before being made into instant coffee. Yes, instant coffee is actually made from brewed coffee solution. After the water is completely drained, the remaining coffee crystals are instant coffee powder, which can be brewed with water and drunk.

There are two main drying processes: spray drying and freeze drying . Spray drying involves spraying the coffee solution into hot, dry air (about 480°F), where the water in the solution evaporates instantly, leaving tiny, round coffee crystals.

Freeze Dryer

Freeze drying is a process that involves several steps. First, the coffee is brewed to create a concentrate, which is then cooled to 20°F to create a frappé. The frappé is then cooled further to -40°F to create ice cubes, which are then ground and vacuum dried, where the ice evaporates instantly, creating instant coffee powder.

Even if you are a fan of hand-brewed coffee, you cannot deny that the production process of instant coffee is really ingenious. If you are a fan of instant coffee, please note that even instant coffee has different coffee qualities from different brands. After a deeper understanding, I hope you can find the instant coffee that suits you!
