As a beginner, finding the perfect coffee roasting equipment to get started seems so daunting, but the truth is you probably already own a suitable first roaster at home. Your oven is a convenient and approachable way to grasp the skills of at home coffee roasting without getting lost in the technical details of a perfect roaster. Even if you are not yet ready to commit to the proper coffee roasting setup, we can teach you how to roast coffee beans in the oven in order to cultivate your skills.
What you need:
-
Baking sheet pan
-
Wooden spoon or other stirring utensil
-
Heat resistant bowl or cooling component
-
Green coffee beans of your choice
-
Oven (preferrably with convection fan)
Steps to Roasting Coffee in the Oven:
Step 1: Preheat your oven to 450 degrees Fahrenheit
Step 2: Spread one layer of green coffee beans onto the cookie sheet evenly. Leave a large hole in the middle of the pan.
Step 3: Once your oven is done preheating, place your pan of coffee beans on the middle rack and observe the roasting process.
Step 4: Pay close attention to your beans and mark the time you place the pan in the oven. Follow the progression of the beans by noting color changes, smell differences, and any other developments as they roast. Keep a close eye for how evenly the color spreads throughout.
Step 5: If needed, take out and stir to ensure all beans are roasting evenly. Listen for the sound of the first crack around seven minutes into your roast. Focus on the attributes of your preferred roast profile at this point. If you are looking for a light roast, now is time to remove your beans and begin a cooldown process. For medium roast wait a couple more minutes, paying extra attention to a smaller popping noise to indicate a second crack before starting your cooldown. Anything beyond this may be too dark for roasting without proper ventilation and may cause problems in your oven.
Step 6: Remove beans from the oven and place into the cooling element immediately. Remove as much chaff as possible by swirling your beans around the heat resistant bowl and blowing air onto them. Small amounts of chaff may remain at the end of this process and will not affect your final cup of coffee. Allow your beans to cool completely before grinding.
Step 7: Grind your beans once entirely cool and store for up to seven days for your freshest roasts.
Now enjoy your first cup of freshly home roasted coffee and take note of what you like. Understanding the roasting process before you begin is a very helpful step in curating the perfect roast, but trial and error helps you create your favorite flavors consistently.
Making notes of how long your roast took, when and how often you stirred your beans, and even what flavors you observe can help you master the fundamentals of roasting coffee at home.
Roasting coffee in the oven at home is a great way to learn the basics and build confidence in your coffee roasting knowledge. This may be a helpful starting point, but is not an effective long term method of this craft. Once you have worked with roasting coffee beans in the oven and began to understand the process better, take the next step into at home roasting. Finding a specialty coffee roaster to take over your at home roasting needs will bring your batches better predictability, consistency, and customization.
How to Choose the Perfect Roaster:
Capacity: How much coffee do you drink regularly and how often do you plan to roast your beans for fresh batches?
Preferred Roast Profile: How dark do you tend to enjoy your coffee? Does your roaster need the capabilities of a dark roast profile?
Effort and Input: How much control do you want of the details of your roasting process? How much effort do you expect to put into roasting every batch? How much time do you set aside to roast your green coffee beans?
Preferred Green Coffee Beans: Picking high quality beans typically arrives with recommendations on how best to fully extract the flavor profile through an ideal roast. Pay attention to the density, moisture content, origins, and other important factors that might affect your roasts.
Choosing your perfect at home coffee roaster does not have to be overwhelming if you consider these inputs and search for what matches your exact needs. Uniformity and manageability are key elements to picking a roaster over learning how to roast in your oven at home. With a few considerations, you can find equipment that matches your exact needs for every roast. While learning how to roast coffee in your oven is a fun DIY approach, a dedicated coffee roaster offers more uniform batches, better flavor development, and much more control over how your roasts turn out.
