Are you interested in trying it yourself? Unfortunately, some people, including you, might hesitate to roast their coffee at home.

Does it require a specific technique? Or is the process complicated? Don’t worry; you only need a guide on how to roast coffee beans at home and some supporting equipment.

Let’s get into what are the stages you will go through when roasting coffee beans at home.

Stages of Coffee Beans Roasting

Each stage plays a vital role in the final flavor of the coffee beverage. By understanding each stage and what it entails, you can produce coffee with a flavor profile to your liking!

1. Raw Coffee

The first stage of coffee roasting that you will go through is to prepare some raw green coffee beans. Their characteristics include being green in color and having a reasonably high moisture content of around 10-12%. You can feel free to use any beans from any region with varied flavor profiles.

2. Drying

Once you have finished preparing the green coffee beans, dry them to remove their moisture content. Place the coffee in a coffee roasting device and set the temperature to 160°c for a few minutes.

This process lasts for a few minutes, and the beans turn yellow. Coffee beans that are still moist will prevent them from being roasted evenly. This may also affect the final result of the coffee.

3. Maillard

Next, the coffee beans will enter the Maillard stage. This chemical process combines the sugar and amino acid content of the coffee beans thanks to high temperatures, around 150-200°C.

This stage is where the complex aroma and flavor of the coffee is formed. The color will turn brownish, and the aroma will start to become fragrant.

4. Browning

Continuing the Maillard reaction, the browning stage makes your coffee beans appear darker and the aroma stronger. At this point, several new compounds are formed that give a cup of coffee its particular flavor profile, including its acidity and bitterness!

5. First Crack & Development

This stage is equally important because it determines how mature you want your coffee to be. Here, each coffee bean will experience increased internal pressure and release carbon dioxide gas, resulting in cracking. If you think about it, the process is similar to raw corn popping into popcorn.

After the first crack, these coffee beans enter the development process. You can stop here to produce a light roast coffee with a mild and slightly acidic flavor.

6. Second Crack

After the first crack, there is also a similar stage- the second crack. This stage generally occurs when the roasting temperature of the coffee reaches 210°C.

If you hear this second crack, it’s a sign that the coffee beans are fully roasted. This results in a more bitter, smoky, and thick coffee. Avoid roasting it too long, as it will cause your coffee to taste bitter, even to the point of being undrinkable!

7. Cooling

Temporarily cool your beans so that the roasting process can completely halt. You can spread them out and air them directly or use a fan as an auxiliary tool. Cooling your beans in the right way will preserve the unique characteristics of each coffee bean!
