What are the different stages of Coffee roasting?
What are the difference between different Coffee roast?

In this article I will provide vague answers to these questions.

Green and Raw Coffee beans need to be roasted before they can be used to make any kind of Coffee drinks. Roasting makes the Coffee beans produce the notable aroma and flavor that we might all be familiar with but depending on how much the Coffee is roasted it gives a totally different character to Coffee beans. During roasting moisture, weight and acidity is gradually lost from the Coffee beans as time progress in the Coffee roaster.

There are 4 types or stages of Coffee bean roasting and they are,

  • ·        Light Roast
  • ·        Medium Roast
  • ·        Espresso Roast/ Medium Dark Roast
  • ·        Dark Roast



Now we are going to talk about what the differences between them are. After finding out the differences you will be able to choose which Coffee roast is the best for you to consume.

Light Roast

Light roast Coffee bean is light brown in color. It has no oil on the surface. Furthermore it has very high acidity and low bitter taste.

Medium Roast

Medium roasted Coffee beans are Dark brown in color. It also doesn’t have any oil on the surface. It has slightly sweet taste than compared to light roast. It has balanced flavor, aroma and acidity.

Espresso Roast/ Medium Dark Roast

Espresso roast Coffee beans are rich dark brown in color. It has some oil on the surface of the Coffee beans. It is bittersweet in taste. The flavor and aroma is much more emerged in this roast while the level of acidity is low.

Dark Roast

Dark Roast Coffee beans are shiny black in color. The Coffee beans are fully covered in oil. It is very bitter compared to other roasts but it has no acidity.

[The price of Coffee beans increases according to the roast. Light roast is the least expensive where Dark roast is the most expensive.]
The simple explaination to this is because as we keep roasting the Coffee bean moisture is lost which causes the Coffee bean to lose weight. Because of this we have to use more raw beans to make let’s say 1KG of roasted beans. This result in use of more raw resources so that’s why darker roasts tend to be expensive.
