The coffee beans are roasted until they can be used as coffee. Without roasting, they are nothing more than a coffee bean. The beans do possess unique qualities that we associate with coffee. However, they are not able to produce the desired flavor until they have been roasted.
Coffee Beans Just Before The Roast
Coffee beans don’t contain beans. They are seedlings, or the seedlings, of a red, purple, or even a blue fruit. The appearance of coffee beans, and their resemblance to a traditional bean, is why they are called beans. The green color of a raw coffee bean indicates that it is fresh.
There are two main kinds of coffee beans: Robusta (or Arabica). Which one are you familiar with? Most often, however, Arabica coffee beans are better than Robusta. However, Arabica coffee beans tend to be of higher quality, have less caffeine, and are more fragrant with more flavors than the Robusta.
Roasting Coffee Beans
The transformation of coffee beans is rigorous, altering the chemical makeup and the physical characteristics of both the coffee bean’s green and brown parts.
To extract the true flavors of coffee beans, they’re roasted. Coffee roasting can be complex and unique. Each roaster will have a different preference. Roasters can vary the roast temperatures and timeframes to accommodate different flavor palettes.
The Art, And Technique Of Roasting Coffee Beans
To a degree, the art of roasting coffee beans depends on your taste. There are many roasting methods available, but they all rely on the final taste of the coffee bean. How long they are roasted is an important factor in determining the final taste and color.
Coffee roasting technology can give you an edge but knowledge is what makes the coffee art. Depending on your intent, each stage can result in a different outcome. Therefore, it is essential to utilize the senses and have experience.

The Science Of Brewing Coffee Beans
Beyond the technical expertise of an individual and modern technologies used, there is science behind roasting coffee beans. This science is what makes coffee.
You can divide roasted coffee into volatile and non-volatile groups. The volatile elements contribute most to the aroma. While the nonvolatile constituents are responsible for the flavors we associate coffee with, such as bitterness and sourness (often determined using caffeine levels).
During roasting, the coffee bean is subject to a range of exothermic or endothermic reactions. The endothermic phase sees energy absorbed in the form of heat. At this stage, coffee beans begin to lose their moisture, change in color, and emit bread-like aromas.
The exothermic period sees energy released in form of heat (in the case of steam). Once the moisture from the coffee bean has evaporated the steam escapes through the bean. This causes the bean to pop or crack. This point is when the coffee beans have begun to develop their true flavors and aromas. They also inherit the rich brown color that we all know.
Coffee Roasted
Technically, coffee is not coffee if it isn’t roasted. This is the simple answer to the question: Why are coffee beans roasted?
The love affair between an individual and the science behind these processes could also be the answer. It could also be answered by saying that coffee consumption is on the rise and that coffee beans must be roasted accordingly.
