How to Roast Coffee Beans at Home
Using a Roasting Machine
Roasting coffee using a roasting machine is the easiest out of all the methods.
There are numerous types and sizes you can find in the market.
The principle behind these machines is like that of a popcorn popper as they also utilize hot air to roast the beans.
- Place the right amount of coffee beans inside the roaster. Please do check the machine’s manual to know the exact amount.
- Close the roaster machine and turn it on.
- Let the machine do its thing until the coffee beans start turning into the color you desire. Remember not to over-roast your coffee as it will burn or produce a darker and more potent taste.
- Pour your coffee into a colander and stir it thoroughly.
- Store it in a cold, dry room that will not be exposed to sunlight.
Using a Stove Top Popcorn Maker
If you don’t have a roaster machine, you can make do using a stovetop. Aside from the essentials, you will also need: an outdoor burner, a baking sheet, and a laser thermometer if you have one.
- Set up your burner, popper, and baking sheet on your workspace. With your stovetop popper, pre-heat until it’s about 400 degrees. You can easily tell this using your laser thermometer. However, if you don’t have one, pre-heating it for about 5-10 minutes is enough to get it into the proper range.
- Add your coffee beans and crank the handle. You will need to continually stir and move the beans to get an even roast. Crank in a steady and consistent rhythm.
- As you continuously crank, the beans will undergo the stages of roasting. Keep cranking and stirring until the beans turn into their desired color. You’ll need to pay close attention during this process as the beans can get burned quickly.
- Once they have reached their desired color, place the beans into a baking sheet to cool down. How long this takes depends on how dark your roast is. Darker roasts generally take a longer time to cool down.
- Once the beans have cooled down, store them in a cool, air-tight container. Many roasters use mason or ceramic jars as they are quite tight.
Continuously experiment with your roasting time.
Don’t be afraid to make mistakes, especially when you are still starting. Roasting times can differ when using different roasting methods.
Failing to adjust these would result in under-roasted and underdeveloped coffee beans.
Moreover, please be mindful of the number of beans you are roasting.
A large batch might make it difficult for the beans to absorb heat and evenly roast, whereas a small set has the risks of burning and over-roasting.
Keep in mind the temperature and batch size to avoid burning.
I also recommend to keep a roasting journal.
With this, you can list down the variables and patterns you see in your roasting.
Over time, you can predict how your coffee beans will react.
If you can, roast a wide variety of coffee beans.
Not only will this enable you to hone your skills, but it will also help you understand the differences in the roasting process.
