Instant coffee tastes very different from freshly brewed coffee. It is often made from inferior 'robusta' beans. It is the result of a complicated scientific process. Coffee is made from coffee beans that are tough and cannot dissolve in water. Nescafe instant coffee doesn't contain actual coffee beans. It is simply a flavored dried solution of coffee that has been subject to a complex brewing process.
Like everything else in food, instant coffee has undergone scientific alteration. Extraction is the process of passing water through a series of cylinders containing ground coffee beans. Each cylinder is heated to a different temperature. In at least one cylinder, pressure is applied to extract more coffee beans. You can buy Nescafe gold coffee pods and capsules in Egypt via Fengany.

Nescafe instant coffee is bitter because the coffee grounds are burned during extraction. They can be exposed to temperatures up to 180°C. The optimum temperature to brew coffee, according to coffee lovers, is between 90 and 95degC. After the coffee solution has been filtered, it is concentrated to get rid of any undesirable particles.
To enhance the flavor, water is removed from this coffee solution. This can be done in a variety of ways. One is to heat the solution to evaporate any remaining water. Dehydration is when the coffee solution becomes dry. Two common methods are Spray drying and freeze drying.
Although the spray drying process is more complex than the others, the principle behind it is to blow hot air through the coffee solution to evaporate any remaining water.
