There are different methods for brewing coffee including the renowned French Press or Espresso and the not so 
popular Turkish method. This article will give you an overview of the four most common methods for brewing coffee.
• Drip Filtration – This is the most popular method for brewing coffee. The way in which the Drip Filtration machine operates is by shooting hot water across ground coffee bean, which is held in a filter that is conical in shape. Then the hot water steadily moves through the ground coffee beans. When the water reaches to the bottom of the filter, it will drain into the container that is kept beneath it.
The conical filters that are commonly used are made of paper; however, there is also gold and stainless steel conical filters. If you choose to purchase paper filters, you should ensure that they are made from papers that are oxygen bleached. If the papers are chemically treated, then it will affect the coffee’s taste. Another thing that you should be aware of when purchasing paper filters is that some of the coffee oils may be caught in the paper filter. The oils are responsible for creating the rich cream when you brew a cup of espresso.
When it comes to Drip Filtration the grind of the coffee is important as well. You can clog the pores of the filter if the grind is too fine. This can be avoided if you use a course grind.
If you continuously reheat the same pot of coffee, it will lose its flavor and eventually become bitter; as such, you should never reheat a pot of coffee.
• French Press/Plunger – The French Press is known as easiest method used to brew coffee. The way in which the 
French Press operates is by mixing the ground coffee directly with water that is near to the boiling point. Once the flavor of the coffee is drawn out in the water, the plunger or press is then depressed and the drawn coffee grind is separated from the brew. Although the process of the French Press extracts a taste that is similar to that of the Drip Filtration, the French Press is able to able to extract a richer flavor from the ground coffee through the extension of the brewing time. However, you should be very careful. You have to have perfect timing when using manual infusion. If you allow the brewing process to extend for a long time, the result will be coffee that is bitter. On the other hand, if the coffee is brewed too quickly, you will have coffee that is weak.
Another important point that you should be bear in mind is that you must utilize course grind. You would not like if the fine ground coffee escapes through the filter (metal) and into the brew. No one enjoys a cup of coffee that is dusty.
• Espresso Machine – Today, the most popular method of brewing coffee is by using an Espresso machine. The 
machine works by forcing extra hot, pressurized water through the fine ground coffee that has been tightly packed. This process of pressurized infusion enables the water to remain in contact with the ground beans just long enough to extract as much of the flavor of the coffee as possible. Next, the water looks for a path through the ground coffee, and then the coffee is poured into your cup. ‘Shot being pulled’ is the term that is given to the process of the water finding its way through the ground coffee.
A good espresso that has used fresh coffee beans is denoted by the richness of the crema. The hazelnut foam that settles on the top of your coffee is known as crema. Crema is produced as a result of the combination of the coffee bean oils and the pressurizing process. Since oils deteriorate after some time, rich crema can only be made by using beans that are fresh.
You should utilize fine grind when using an Espresso machine. If you use a course grind, the water will not be able to properly infuse the ground coffee. You can use a course grind to produce good coffee; however, it will taste more like coffee that has been brewed using the Drip Filtration method.
• Moka Pot Coffee – The Moka Pot is also referred to as the Stovetop coffee pot. The Moka Pot is a 3 piece pot that is available in various sizes including capacities of 2, 4 or 6 cups. At the base of the pot is the water reservoir, in the middle is the coffee basket, and at the top is the coffee that has been brewed.
The method of brewing coffee with the Moka Pot is rather easy. The water in the reservoir is heated when you place the pot on the stove top. Once the water begins to boil, the steam will rise and the water will begin to push to the coffee grounds that are above. The water will continue its journey up to the central funnel, until it ends up in the top chamber. When the coffee ceases to move in the top chamber, that is when the process ends. Depending on the size of the cup used by the Moka Pot, the process will only last for a few minutes.
The grind should be similar to that used in the Espresso machine or it should be finer. You can fill the coffee basket by heaping a lot of ground coffee into the basket, and then screwing the two pieces together. You should not be worried about compacting the coffee grounds. Once you screw on the top half of the pot, the filter screen will compact the coffee grounds. When the brewing has ended, you should be left with coffee grounds that are compacted and dry.
