The taste of coffee is directly related to the region it comes from, and it also depends upon the climate and soil that was used in the growth process. Coffee beans themselves have hundreds of different compounds on them that contribute to their flavor and aroma overall. There are two various types of coffee beans, Arabica and Robusta, and they both have a variety of different flavors available, depending on how they were cultivated. Arabica is the higher quality and more gourmet bean, and Robusta is seen to be the cheaper filler bean that is of a lower quality.
There are, quite literally, dozens of coffee-growing regions throughout the world, and while it may seem confusing, it can be a lot of fun trying out new and different varieties of coffee offerings to find the right blend for you.But regardless of which type of bean that you choose, the harvesting and roasting process do have a direct effect on their taste overall, which is precisely why you need to focus on high-quality methods in these processes. It is best to look for top organic coffee brands or Fair Trade harvesting of your coffee beans because they can guarantee you that you will be getting a higher quality in the product. Organic specifically means that your coffee beans were not harvested with the use of pesticides, and the farmers also practiced crop rotation because it keeps the soil rich and fertile. Fair Trade coffee harvesting guarantees the farmers set wages that are fair, so it allows the farmers to focus more on the quality of their crop since their wages are guaranteed.
More specifically, the acidity is what is going to leave an aftertaste in your mouth after you take a sip of your cup of Joe. This is a good thing because it gives a brightness to the flavor of the coffee. If you would like a lighter taste, then you will want to look for low acidity, and a deeper taste will be a full and bright acidity.
