How are Different Types of Coffee Made?
The process of making espresso coffee includes pushing a small amount of boiling water through the compression of fine coffee powder.

The espresso coffee also forms the base for many other types of coffee like the café latte, macchiato, mocha, Americano, etc. Naturally, the espresso coffee has more caffeine compared to other types of coffees. Some people prefer to drink espresso shot directly by adding a thick cream layer to the shot.
Cappuccino is prepared by mixing espresso with hot milk, and a thick layer of cream is used to give it a thick texture. To make this coffee, espresso is first poured into the cup. The amount of espresso will decide how strong or light the coffee is. After this, hot milk is added. Lastly, a thick layer of milk foam is added.
Unlike Cappuccino, this coffee is made using only espresso and steamed milk. Since no cream is used in this type of coffee, the quantity of this kind of coffee is fairly less than Cappuccino.
Americano is for those who do not like milk to interfere with coffee. In this, espresso is brewed with hot water to give a powerful dose of coffee. Some people like to have some milk on the side with this type of coffee to blend the strong taste of coffee.

In many places, there are traditional methods of processing also used. The fruit pulp of the coffee fruit and the coffee seed or the coffee bean is left for drying. There are three methods for further processing of the coffee that is the wet method, the dry method, and semi-dry method.
- Wet Method: A particular kind of equipment or machinery along with the proper quantity of water is required for the wet method of processing coffee. This process involves the fermenting of the coffee bean. The fermentation has to be done very carefully to ensure that the coffee does not lose its flavor. The machine based wet method of processing coffee the separation of coffee bean is through scrubbing mechanically.
- Dry Method: The dry method of processing coffee is an ancient practice. Once the harvesting is done, the entire coffee cherry is cleaned and put in the sun, to dry. While the coffee cherries are put for drying, they are turned around continuously to ensure that drying takes place from all sides. It can take about four weeks for cherries to dry thoroughly. If the plantations are huge, then the coffee cherries are dried using machines after they are dried in the sun for few days. Drying is the most important part of making coffee. If the beans are over dried, then they can become brittle.
- Semi-Dry Method: The semi-dry method of processing coffee also called “Giling Basah” is very popular in Indonesia and Brazil. It is a very hybrid approach. This process is also known by other names such as Wet Hulling, Wet Grinding, etc. Then the dried coffee cherries are stored until they are put into the further process of milling, sorting, grading and packaging.
Further, let us see how is coffee Decaffeinated.
Decaffeination of Coffee
Extracting caffeine from the coffee before roasting involves the process of decaffeination. The process of supercritical carbon dioxide extraction is the most widely used method.

This process can remove up to 97 percent caffeine from the coffee bean. An alternative to this is the solvent extraction method. This method is also very popular. In this method, the caffeine is extracted from the coffee after roasting with the help of the solution. Further, let us understand how to make coffee powder.
