11 Easy Steps to Roast Coffee Beans at Home
There are many ways to roast coffee beans at home.
Here is the step-by-step process of roasting green coffee beans using a coffee roaster.
Step 1: Pick the Right Coffee Green Beans
Always ensure that the green coffee beans you buy have a uniform size and color to get the best roast. Also, the beans must have a flavor profile suiting your taste.
Step 2: Get the Coffee Roaster
Though you can use a skillet, pan, popcorn popper, or even an oven, a coffee-specific roaster is best if you don’t want any confusion or hassle. They help roast the green beans evenly.
Take your roaster outside for the roasting process because it needs a lot of ventilation to let out the smoke.
Step 3: Put the Green beans Into the Roaster
While adding the green beans, remember that if you take 4 pounds of green coffee beans, you’ll get 2 pounds of roasted coffee beans. This is because exposing the green beans to hot temperatures will decrease the amount of water in them.
So, take twice the number of green coffee beans to get your desired number of roasted coffee beans.
Step 4: Cover the Roaster Well and Set the Right Temperature
Cover the coffee roaster well with a lid because there are chances that the steam from the coffee beans might pop off. Then, set the heat level to 285 degrees Fahrenheit.
Step 5: Initiate the Yellowing Phase
After approximately 10-15 minutes, the coffee beans dry and turn yellow. They give off a grass-like smell at this point.
Wait a few minutes, and you’ll see the steam rising from the yellow coffee beans. By now, they should lose all their water, and the actual roasting will begin.
Step 6: Let the First Crack and Browning Phase Begin
Now, raise the heat to 355 degrees Fahrenheit. You’ll hear a crack or a pop as the coffee beans start turning light brown. The coffee beans taste sour in this phase.
However, let the coffee beans get browner. For more roasting, increase the temperature to 430 degrees Fahrenheit. This phase of roasting will give you light and medium roasts.
Step 7: Set in the Second Crack Stage
After a few minutes, you’ll hear another crack sound, indicating that the coffee beans are now in the process of dark roasting.
The coffee beans will turn a darker brown shade, filled with an intense aroma and flavor.
Step 8: Cool the Roasted Beans
Once the green coffee beans are roasted, cool them down. For doing so, keep transferring them from one colander to another till the temperature of the beans comes down to a comfortable level to touch.
While you’re cooling them down, try to remove the chaff of the coffee beans as much as possible.
Step 9: Vent Off CO2
Before grinding the roasts, wait 1-3 days to vent off the CO2 gas that builds up eventually. It can decrease the longevity of roasted coffee beans.
Step 10: Grind the Beans and Brew Them
After degassing, you can grind the roasted beans and brew them for a good cup of coffee. Use them within a week or 10 days to get the best flavor and enhanced freshness.
Step 11: Store the Remainder Roasted Beans Safely
Store the roasted coffee beans in a vacuum bag or airtight container. Otherwise, oxidation will cause the flavor and texture of the coffee beans to change. Also, they shouldn’t be exposed to heat or moisture.
Thus, now that you know how to roast coffee beans at home, it will be a learning experience for you each time you do so. You’ll eventually learn what flavors you like or the right temperature to roast your green beans.
