Coffee beans

Coffee beans are the raw material of coffee, and they are the seeds of coffee trees. There are usually two main types of coffee beans: Arabica and Robusta. Arabica coffee beans are generally considered to be of high quality, with lower caffeine content and higher acidity. Robusta coffee beans, on the other hand, have higher caffeine content and lower acidity.


The color of coffee beans can vary depending on the degree of roasting. Lightly roasted coffee beans have a lighter color and a more acidic taste, retaining more of the original flavor of the beans. Medium roasted coffee beans have a darker color, a more balanced taste, and a certain level of acidity and bitterness. Dark roasted coffee beans have a very dark color and a bitter taste, as caramel compounds are formed during the roasting process, giving the beans a rich caramel and chocolate flavor.


The origin of coffee beans also affects their flavor. Coffee beans from different regions have unique characteristics. For example, Brazilian coffee beans usually have a nutty and chocolatey flavor, while Colombian coffee beans have a mild acidity and a rich texture.
