Drinking a great cup of coffee in your local shop sounds fancy and more convenient. However, have you ever thought of roasting the beans yourself? It may seem a lot of work, especially if you often see how your local barista looks super busy making coffee at the shop.

The truth is, roasting beans is easier than you thought. You would only need a few pieces of equipment and a good supply of fresh green coffee beans. Likewise, roasting beans yourself allows you to create your beverage according to your liking.

What happens to coffee beans when roasting?

When you roast a bean, you are forcing the moisture out of the bean, drying, and expanding it. The natural sugars in the beans either turn into carbon dioxide or be caramelized to bring the flavor. After the process, your green bean will turn brown, lighter, and larger.

10 Stages of Roasting Coffee Bean

According to pro roasters, there are ten levels of roasts of beans. However, that does not mean that you need to roast your beans up to the tenth level since this is just a guide for identifying bean roast. Remember that you can roast them according to your preferences.

With that said, here are the ten stages or levels of roasting coffee beans:

Stage #1: Green

The beans will appear and stay in their green essence after a few seconds or minutes of exposing them to heat.

Stage #2: Yellow

At this time, the beans will turn yellow and produce a significant grassy smell.

Stage #3: Steam

The beans have water inside of them. At this stage, the water will rise and evaporate from the beans.

Stage #4: Cinnamon Roast

It is also known as the “first crack,” and this is where the roasting process formally begins. As the sugar inside the beans caramelizes, you will hear a cracking or popping noise.

Stage #5: City Roast

It is the minimum level of roast acceptable to most people’s tastes. Roasters at home and coffee shops serve coffees at this level of roast.

Stage #6: City Plus Roast

It is the level of roast popular and familiar to most coffee drinkers. As the sugar continues to caramelize and the oil migrates, the beans swell and reach this level of roast.

Stage #7: Full City Roast

At this stage, the roasted beans become darker in color as they verge for the second cracking.

Stage #8: Full City Plus Roast

It is the second cracking of the beans. At this stage, the bean will have a more violent cracking. As a result, it will reveal even more intensity of flavor.

Stage #9: French Roast

Also known as the dark roast, this is the utmost limit of roasting. The sugar will burn even further, smoke will become pungent, and the beans will break down.

Stage #10: Burn

You will know that your beans are burnt if its smell turns from pungent into terrible.
