Coffee preparation is the process of turning coffee beans into a beverage. While the particular steps vary with the type of coffee and with the raw materials, the process includes four basic steps; raw coffee beans must be roasted , the roasted coffee beans must then be ground, the ground coffee must then be mixed with hot water for a certain time (brewed), and finally the liquid coffee must be separated from the used grounds.

In percolation, the water passes through the coffee grounds, gaining soluble compounds to form coffee. Insoluble compounds remain within the coffee filter. Coffee can be brewed in several different ways, but these methods fall into four main groups depending on how the water is introduced to the coffee grounds: decoction (through boiling), infusion (through steeping), gravitational feed (used with percolators and in drip brewing), or pressurized percolation (as with espresso)....

When roasted, the green coffee bean expands to nearly double its original size, changing in color and density. As the bean absorbs heat, its color shifts to yellow, then to a light "cinnamon" brown, and then to a rich dark brown color. During roasting, oils appear on the surface of the bean...

It’s iconic across the globe, and the base of more delicious coffee drinks than we’d like to count. But why is an espresso so special?
Read MoreCoffee drinks are made by brewing water with ground coffee beans. The brewing is either done slowly by drip, filter, French press, cafetière or percolator, or done very quickly under pressure by an espresso machine...
The origin of the name "macchiato" stems from baristas needing to show the serving waiters the difference between an espresso and an espresso with a tiny bit of milk in it...

The whole coffee beans are ground, also known as milling, to facilitate the brewing process. The fineness of the grind strongly affects brewing. Brewing methods that expose coffee grounds to heated water for longer require a coarser grind than faster brewing methods. Beans that are too finely ground for the brewing method in which they are used will expose too much surface area to the heated water and produce a bitter, harsh, "over-extracted" taste. At the other extreme, an overly coarse grind will produce weak coffee unless more is used. Due to the importance of a grind's fineness, a uniform grind is highly desirable. If a brewing method is used in which the time of exposure of the ground coffee to the heated water is adjustable, then a short brewing time can be used for finely ground coffee.
This produces coffee of equal flavor yet uses less ground coffee. A blade grinder does not cause frictional heat buildup in the ground coffee unless used to grind very large amounts as in a commercial operation. A fine grind allows the most efficient extraction but coffee ground too finely will slow down filtration or screening. Ground coffee deteriorates faster than roasted beans because of the greater surface area exposed to oxygen. Many coffee drinkers grind the beans themselves immediately before brewing.
There are four methods of grinding coffee for brewing: Burr-grinding,Chopping, Pounding and Roller grinding
