Instant coffee is a dry coffee extract obtained by evaporating the water in the coffee extract. Instant coffee can quickly dissolve in hot water, and occupies less space and volume in the process of storage and transportation, which is more resistant to storage.

Instant coffee is different from the more complicated traditional coffee brewing methods, so it has been widely popular.

Instant coffee is not as good as traditional coffee made from fresh coffee beans. It has higher fat and sugar content, lower quality protein and caffeine, and may lose the essence of coffee in the production process.
