Roasting is a process where heat is supplied to the green bean, which makes its colour change from green to a desired brown colour, depending on the roast profile.
What is a roast profile?
A roast profile is a description of how much a coffee bean has been roasted. It is like a recipe. A roast profile can be light, medium or dark and each of these profiles have their own "recipes".
There can be hundreds and thousands of different roast profiles, according to the type of coffee beans, their flavours, origin, and other aspects.
Let's talk about these roast profiles.
- Light- The colour of the beans is light brown
