Green coffee beans: The science behind why they are green and how to roast them to get the best cup of coffee with the best taste

When you roast green coffee beans, the content of chlorogenic acid decreases. This is what makes the beans turn yellow and then brown. In this blog post, we will take a closer look at the science behind green coffee beans and how to roast them to get the best tasting cup of coffee!

What are green coffee beans and why are they green?

Coffee beans are coffee seeds that have not yet been roasted. The coffee roasting process brings out the rich taste and aroma of coffee that we know and love, but it also makes the coffee beans turn brown. Before the coffee beans are roasted, they actually have a light green color. So why are coffee beans green? It all has something to do with the coffee plant. Coffee plants produce coffee cherries, and each cherry contains two coffee beans. Once the coffee cherries are picked, the coffee beans are extracted and then dried. At this point, the coffee beans are still green. It is only when they are toasted that they turn brown.

The science behind roasting green coffee beans

The process of roasting coffee beans is a crucial step in creating a delicious cup of coffee. But what really happens when the coffee beans are roasted? It turns out that the science behind this process is quite complex. The beans are roasted to release the coffee's unique taste and aroma. The roasting process also has the effect of reducing the bean's natural acid content.

During roasting, the coffee beans undergo a series of physical and chemical changes. The beans grow in size and change color, from green to yellow to brown. As the temperature during roasting increases, so does the rate of these changes. At lower temperatures, the coffee beans retain e.g. more moisture, resulting in a lighter toasting. Conversely, higher temperatures will result in a darker roast.

The roasting process itself is also responsible for producing certain desirable flavor nuances in coffee. There is e.g. Maillard reactions when the coffee beans are roasted at high temperatures. These reactions cause various compounds in the coffee beans to be broken down and form new flavor molecules. This is why coffee that has been roasted for a long time often has a more complex taste than coffee that has been roasted for a long time
