Coffee Brewing Techniques
Generally we know only about the roasting of coffee beans but the extraction of the coffee flavor from the beans through the brewing technique is the most important aspect of coffee-making. It is the final process of coffee making. Today, we have many forms of coffee brewing techniques which are used for both the commercial and home purposes. They are,
Flavor extraction length :
Generally, the length of extraction time is directly related to the grind coarseness. The smaller coffee particles take only a shorter extraction time. The french press coffee is the longest, with the coffee and water lasting more than four minutes. The Espresso method requires only less time, about twenty-five seconds, and the coffee granules are too smaller in this type.
If the coffee and water stay together for a long time , then it will make the coffee bitter. On the other hand, if the granules are large and if the extraction time is short then the coffee will lack flavor because of under-extraction.
Drip brew:
Nowadays, most of the home brews are produced through the drip process. The technique is simple enough where the hot water is poured over a medium-ground coffee within a filter and the water goes through the coffee grounds and drips into a holding container. There are so many variations on these drip brewers with different functions and are available for both the home, commercial use.

The machines have warming hot plates, for keeping the coffee warm. But the continuous heat will make the coffee bitter.
Single-Server Systems :
These machines are exclusively used for the commercial purposes. Nowadays, most of the people buy for their home for their convenience. The P re-packaged coffee is inserted into the machine with a push of button and the coffee starts to come out. There are many variations in this method. Some machines can brew with less water and make stronger coffees. One complaint is that, these machines use proprietary packaged coffee and the quality and freshness cannot be guaranteed.
French Press / Press Pot / Cafeteria / Plunger Pot :
The French Press pot has two parts. They are, the beaker and a plunger which has a wire-mesh filter. At first, heat the brewing water and pour it over the coffee grounds in the beaker. Let the coffee boil for about 3 to 5 minutes before putting the plunger in and it will be easy to push the drugs with the filter mesh easily. Now stir the brew once and it is ready for drinking. Then Pour the coffee into the drinking mugs after brewing.
Espresso :
The Espresso is prepared by forcing the hot water steam through a finely grounded coffee in a certain pressure. The resulting brew is called as an espresso and it is developed by the Italians at first. It is different from the regular coffee which is produced by the process unlike the regular brews.
