Coffee can be roasted in a variety of ways. The method you choose should be influenced by how much roasted coffee you require and how much money you wish to spend. Whether you choose a do-it-yourself approach or a small appliance is largely determined by whether you want more or less automation.

How To Roast Coffee At Home

This is how to roast coffee at home:


  • Cast Iron Skillet
  • Stove/Hot Plate
  • Balloon Whisk
  • Laser Thermometer
  • Smartphone/Clock


  • 1 Bag Unroasted Green Coffee Beans
  • 1 Airtight Container


  1. Prepare your workspace. Gather all of your supplies, including your beans. The number of beans required will be determined by the size of your skillet. Fill the skillet with green beans, making sure there are no more than a few layers. This is necessary for an even roast.
  2. Make sure your workspace is well ventilated, as there will be plenty of smoke. Place your skillet onto the stove and turn it on. You want to get to around 340-350F before proceeding. Adjust the stove temperature until you reach this point.

A laser thermometer is the best tool for measuring temperature.

  1. So now our skillet has reached the proper temperature, we can add the beans. When you add the beans, the temperature of your skillet will drop. You can adjust the heat to get it back to around 340-350F.
  2. Once the beans are in the skillet, start whisking. Make sure to work quickly while avoiding losing any beans. We can rotate our beans in layers instead of just moving them around the pan by using a whisk.
  3. As you whisk, you'll notice the coffee changing color and producing a lot of smoke.

Continue roasting your coffee while constantly agitating it with the whisk. You will eventually hear your beans cracking. This is the first crack, and the roast is light.

  1. When you're satisfied with the consistency and color of your beans, remove them from the skillet and place them in a bowl.

Once the chaff has been removed, your beans are ready to grind and brew, or store in an airtight container!

What Do You Need For A Coffee Roaster?

Roasting machines are costly toys that will undoubtedly be the focal point of any roasting facility. Smaller pieces of equipment, such as sample roasters, coffee bag sealers, humidity readers, and color meters, will also be required.
