Roasting Your Own Coffee Right At Home
Roasting coffee at home is really quite a simple concept however there is a huge margin for error. If you like to experiment with different blends of coffee home roasting is a good way to do this but it will take some pratice. Keep in mind however that when you do become proficient in your roasting skills you will still need a quality machine like the Jura Capresso ENA 5 if you want to achieve an excellent espresso beverage.
The concept of roasting your own beans is a simple one. You will need to be able to expose the beans evenly to air that is the temperature of at least 400 degrees for 5-10 minutes. You also must know the right moment to cool them. Although this may sound easy it is sometimes difficult to tell when to stop the roasting and also keeping the beans from roasting unevenly.
To start a new roast you will need a perforated surface that is oven proof such as a normal petal like vegetable steamer. Myself I bought a big pizza pan with small holes in the bottom. You need to use something perforated so that the air can flow around the beans more evenly.
Layer a thin layer of green beans on the surface of your pan or steamer (if using a vegetable steamer you can fit a thin layer of approx. 3 oz. of beans). The layer of green beans can be up to 2 beans deep.
Heat up your oven to four hundred twenty five degrees. Place your green beans into the oven on the middle rack once the oven has reached temperature. You will need to set a timer for ten min.. If you are trying to recreate a roast that you are fond of it would be helpful at this point to have a sample of that roast handy so you can use it as a color reference.
Shortly the coffee will start to release bound moisture because of the heat and you will start to hear crackling. After 1-2 min. of the crackling sound it is a good time to check on the shade of the beans.
Make sure to only open the oven only long enough to view the shade of the beans, believe me when I say that beans that are roasting smoke quite a bit and don’t smell like you would think. You will want to look at the bean shade every few minutes til the shade is a bit lighter than what you are going for.
Because the beans will still cook after you take them out of the oven, you will need to remove them prior to reaching the desired darkness. If you can place your beans in a protected area outside to cool so the smell doesn’t fill your entire house.
Don’t worry if your beans look a bit uneven or darker in spots than you were trying for. Your home roast will still taste better than any stale grocery store bought bean that is available.
Once a week I roast beans, let them cool and put them into my Jura Capresso ENA machine to use (I own the ena 5 cherry red… I love it).
