■Types of Coffee
Depending on how to prepare coffee beverage, the following types of coffee can be considered:
Espresso: One kind of coffee (black coffee) made under pressure through an espresso machine, after having pulverized roasted coffee beans with a grinder. Because espresso preparation is done at higher temperature and more pressure, it differs from the coffee produced by the coffee drip method. In fact, what we do is to pass a jet of hot water vapor through a filter full of coffee. All the aroma and taste of coffee beans which are transferred to the infusion are removed by the jet of pressurized steam removes. Then a type of very tasty and frothy coffee is produced. Sometimes espresso is mixed with milk to give different blends, such as cappuccino, white coffee, coffee chocolate, American coffee.
Drip coffee: One type of coffee cooked by pouring water over roasted, ground coffee beans contained in a filter. Water passes through the coffee, absorbing its oils and essences, solely under gravity, then seeps through the bottom of the filter. The used coffee grounds are kept in the filter with the liquid falling (dripping) into a collecting vessel such as a pot or carafe.
Brewed pot coffee: The traditional coffee brewed at home without the aid of any machine, and with the aid of a pot and a strainer. Because it consists on a natural way of obtaining the coffee properties by methods of the decoction mean in which coffee beans are directly cooked in water, it is the most natural form of preparing this beverage.
