Everything about Roasting Raw Coffee Beans

If you thought coffee beans come in brown color, here’s a fact for you. Coffee beans are seeds of tiny fruits. The coffee plant can simultaneously grow flowers and red fruits called cherries. These cherries are then picked from the plant and the seed inside them are the coffee beans.

However, the coffee beans we find by this process are green. It’s only after roasting the beans that we get brown beans which can then be crushed and prepared for a cup of delicious coffee.

Process of Coffee Roasting

As mentioned, coffee beans extracted from coffee plants are green in color. They have a jade-like look and smell like freshly cut grass. To get the depth of flavors and the distinct aroma that coffee beans have, there are several different coffee-roasting techniques that you can apply.

The techniques generally involve high temperatures (350F to 500F), a variation in airflow, and finally the audible cracks. Yes, that’s how we get the brown coffee beans. The entire roasting process is done under constant visual observation and the roaster uses all his skills and experience to bring about the finest roasts. The roasts can range from light, medium, medium-dark, and dark depending on the roasting process.

Here is a brief rundown about the coffee roasting process.

Stage 1

In this stage, the heat builds up gradually, and the beans turn from green to a slightly yellow color. The beans emit a grassy aroma and the water inside the beans begins to evaporate as steam.

Stage 2

This is the stage where real roasting begins. The escalation of temperature and airflow will make the beans crack. The sound is audible and the beans generally crack after 6 to 8 minutes. The cracking sound is like a popcorn crack and if you take out the beans at this stage, it results in a mild taste with a somewhat heavy acidity.

Stage 3

In this stage, as the sugar of the coffee beans further caramelizes, the beans swell and the roast obtained results in coffee with balanced acidity and flavor. This type of roast is very popular and aromatic. The roasts gain a medium-brown color.

Stage 4

In this stage, as the coffee beans turn darker, the flavor of the beans intensifies as well. The roasts are termed medium-dark, and they are rich and dark in color.

Stage 5

This stage sees the coffee beans on the verge of a second crack to give it a dark roast. This is the final stage of roasting and any roasting done beyond this will render the coffee beans completely black in color and all the flavor and aroma are completely burned off from the coffee beans.
