Without a doubt, coffee flavor and taste are the main things to determine our coffee preference. And the crucial factor to make a good coffee aroma is the roasting process. Based on how you do the coffee roasting, you will feel the completely different taste and aroma of your coffee. 

What is Coffee Aroma?

Basically, coffee aroma is the smell of coffee in the simplest way. Besides the four main types of aroma that you just read from the coffee mind aroma wheel, there are more than 800 aromatics in coffee according to the specific testing or experiments. Because it is released with flavorful combinations through the air, therefore, the more coffee fresh, the more smell it has.

Fresh coffee not only tastes good but also has a strong fresh aroma that you can feel. Anyway, the process of roasting determines the level of your coffee smell. In short, if the roasts are getting darker, then it means you are going to have a strong coffee aroma, giving a better feeling to you while enjoying coffee. Moreover, coffee flavor is considered as one of the top factors that professional coffee tasters or lovers use to judge the quality of the coffee.

What Is Coffee Aroma And Its Relation To Coffee Taste?

Actually, the green original coffee beans themselves do not have much smell. And coffee aroma comes through the roasting process which makes the coffee aroma unique and a nice coffee. And, what we think as a flavor, in fact, is a coffee aroma. As we mentioned, there are several different types of taste such as salty, sweet, sour, and bitter. When you feel these tastes with your tongue, it is flavor, and when you receive them in your nose, then it is the aroma. Additionally, coffee aroma and its taste have a very close relation. For instance, if the coffee is full of rich flavor, then the scent of that coffee will be very rich as well. 

Which Component Creates Which Aroma?

The coffee aroma is actually formed with various components such as protein, acid, and carbohydrates, and so on according to some scientific facts. And these different components create different flavors and tastes of coffee during the roasting process. Below are the common components that created a unique and fresh coffee aroma.

  • Pyrazines can create a nuttiness aroma so that you can smell it even with a very little amount of coffee. Therefore, it is one of the most important and most contributable components to the coffee aroma.
  • The breakdown of amino acids can produce a coffee aroma that is sweet and fruity.
  • Ketones contribute to coffee aroma a lot and the smell is very aromatic as a result of the auto-oxidation of fatty acids. Ketones usually create a fruity or musty aroma. 

How Do We Perceive Coffee Aroma?

Now we have some ideas of how the coffee aroma is formed with those components and what kind of aroma that they can produce. But you should also be aware that it is perceived in many various ways.

According to the research, it is proven that there are more than 800 components created during the roasting process. However, only less than 30 of them actually contribute to the coffee taste and aroma actually. Then the components are balancing each other to produce the best flavor and aromatic coffee. 

If you pay attention to making a cup of coffee,  you will see the scent difference between the grounding coffee and the cup of coffee with water. When you smell the grounded coffee beans, then you will smell all of those aromas. But if you add water to it to make a cup of coffee, then you will smell a quite different aroma compared to before. It is simply because some of the components are extracted while mixing with water.

One more thing that you should pay attention to is the level of the extraction that we just mentioned above. Because the components extract at different levels since they are all different. And based on the extraction level, the coffee aroma will be changed as well.
