In the "wet process", the fruit covering the coffee beans is removed before they are dried. Coffee processed by the wet method is called wet processed or washed coffee. [5] The wet method requires the use of specific equipment and substantial quantities of water. The coffee cherries are sorted by immersion in water.
To produce instant coffee, the soluble and volatile contents of the beans, which provide the coffee aroma and flavor, have to be extracted. This is done using water. Pressurized water heated to around 175 °C (347 °F) is used for this process. The coffee concentration in the liquid is then increased by either evaporation or by freeze ...
