Instant Coffee is usually preferred for it's speed in preparation and has been on the market since 1950's. All you need to do is add hot water to the coffee granules and you have your cup of instant coffee. Instant coffee also has a long shelf life and is easy to store. It is important to store the instant coffee dry though. Most coffee drinkers prefer the taste of freshly brewed coffee instead of instant coffee. Instant coffee is still very popular in the world and is often called 'Café Puro'. Instant coffee is often produced from low quality coffee beans. The high quality coffee beans are usually used for the sale of whole beans. Although many coffee companies use high quality beans nowadays. Instant coffee is produced by roasting, grinding and brewing coffee beans in a giant tank. The coffee particles are then extracted and the remaining liquid is evaporated using either a freeze drying or a spray drying method. The freeze drying process is the superior and more complicated one of the two. During the freeze drying process the coffee liquid is frozen to minus 40 degrees Celsius. This causes the water particles in the coffee to form ice crystals. The ice is extracted from the granules using a method called sublimation, a special chamber dries the particles at a very low pressure leaving behind a soluble coffee. There is another technique that is called spray drying. During spray drying the concentrated coffee is sprayed together with hot air into the top of a high tower. The water evaporates, due to the heat, as it falls, so that only the dried powdered coffee remains. The spray drying process is easier than freeze drying but many flavours of the coffee are lost because of the high temperature. You can find some more information about Instant coffee here and here.
