With the popularity of coffee, people continue to look at options to enhance the coffee experience. One such option is purchasing green coffee beans and home roasting. Roasting your own beans results in higher quality coffee that is cheaper than purchasing pre-roasted beans. Higher quality in that the coffee is fresher providing richer flavors and aromas at your own personal flavor preference. Popular methods for roasting coffee include: home coffee bean roaster, air blown popcorn popper, oven top (crank) popcorn popper, or cast iron skillet / frying pan
Coffee starts to lose flavor within days of being roasted. Buying pre-roasted beans and home grinding lessens flavor loss, but it still doesn’t come close to the freshness offered by home roasting. Home roasting is not a walk in the park, but with patience and practice you will be able to make exceptional coffee that meets your personal flavor profile. We recommend that you start with a small amount of green coffee and follow these basis steps:
- Heat beans to a temperature of 375 to 550 degrees;
- Coffee beans must be in constant motion to prevent uneven roasting and scorching;
- Must vent properly as roasting produces a lot of smoke (oven fan, open window; roast on barbeque);
- The beans must be cooled quickly to prevent over roasting.
Coffee Roasting using a cast iron skillet
- Pre-heat the skillet using a medium setting ( temperature of approximately 450).
- Add up to 10 oz. of green coffee beans and cover (use less coffee until roasting process is mastered).
- Every 15 to 30 seconds and holding the cover, vigorously shake the skillet over the burner for five seconds. Continue this process until coffee is removed from the burner. Once the beans begin to make a cracking sound, smoke and coffee aroma will begin.
- Every minute after cracking begins, check the color of the beans by removing cover and visually inspecting.
- Once the desired color is achieved (see chart below), remove beans immediately and place in a separate container (preferably a metal colander) to cool by stirring and/or tossing.
- Once beans are cooled, remove the chaff (dried bean cover that has separated from the bean).
- Store in container, but do not seal the container for the first 24 hours as roasted coffee continues to release gases.
- After 24 hours seal the container to enhance coffee freshness.
