After several hours of research and trial and error, I found the 4 most effective ways to roast coffee beans.

In this post, I’m going to walk you through 4 different methods on how to roast your coffee beans at home. The methods are pretty easy to follow and quite beneficial for the freshest, most delicious tasting coffee.

Roast Levels:

  • Light Roast – Occurs at the first crack or an internal temperature of 356-401F.
    • A.K.A Cinnamon Roast
  • Medium Roast – Occurs at the second crack or an internal temperature of 410-428F.
    • A.K.A City and City Plus
  • Medium Dark – Continue roasting after the second crack or until an internal temperature of 437-446F.
    • A.K.A Full City and Full City Plus
  • Dark Roast – Continue roasting until 464F but below 482F.

4 Ways to Roast Coffee Beans:

  1. Pan – Most cost-effective way as most of us already have this at home.

  • Equipment Needed:
    • Green Coffee Beans
    • Cast Iron or Steel Pan Uncoated
    • Stove
    • Whisk or Wooden Spoon
    • 2 x Metal Colander
    • Air-tight container
    • Infrared Thermometer
  • Steps:
    1. Maximize Ventilation – It’s going to get real smoky.
      • Turn on fans, open windows, etc.
    2. Place pan on medium heat (450F).
    3. Spread a thin layer of green coffee beans on the pan.
    4. Stir and DO NOT stop.
      • A whisk will be more effective here because it agitates the beans compared to a wooden spoon. Agitating the beans allows them to rotate, which results in a more even roast.
    5. Listen for the first crack after 4-5 minutes or when beans reach an internal temperature of around 380F. This will last for 1-3 minutes.
      • Light Roast
    6. Listen for the second crack after 1-3 more minutes or when beans reach an internal temperature of around 420F.
      • Medium Roast
    7. If you want a Medium-Dark Roast, continue roasting until an internal temperature of 437-446F
    8. If you want a Dark Roast, continue roasting until an internal temperature of 464-482F.
    9. Transfer the beans to a metal colander and shake to get rid of the husks.
    10. Leave beans exposed for about 12 hours to de-gas.

  1. Oven – Another cost-effective way to roast!
