No matter how big of a coffee geek you may be, you are not a true coffee cultist until you know how to roast coffee beans at home.
Considering the fact that we are living in an era where doing things yourself is glorified, it is worth a try.
Things you will need:
The first thing that you will need to roast coffee beans at home is green unroasted coffee beans, which you will readily find online.
You most likely already have an oven, and it will be even better if it is near a window. Other things that you will need include a colander, perforated disposable roasting tin or a stainless steel wire mesh strainer, a large spoon and oven mitts.
Roasting your coffee:
- The oven should be preheated to 500 degrees Fahrenheit.
- The beans should be spread out in the colander, strainer or tin, only a single layer deep.
- The bowl should be placed directly on the middle shelf and the oven door should be closed quickly, so that too much heat does not escape.
- Charring the coffee beans can be avoided if they are agitated intermittently during roasting, every minute or so.
- Again, leaving the oven door open for too long should be avoided so that the heat does not escape.
- After almost 5 to 6 minutes, the first “crack” will be heard. Technically, this is a sign that the beans are now lightly roasted.
- After waiting for a minute more or two, the beans should now be constantly checked for color. An already roasted coffee bean should be used as a guide.
- The beans can be removed from the oven once the beans start to reach the desired color.
- The heat should be increased to 525 degree Fahrenheit if the beans do not reach a brown color after 12 minutes.
- The beans should be removed from the oven and should be transferred to a new colander, perforated tin or strainer. If the beans are left in the heated vessel, then they will keep on roasting, so the cooking stops once they are transferred.
- The beans should be shaken or stirred using a large spoon so that their chaff or skins fall away. The chaff can also be softly blown away.
Like fine wine, coffee beans that have been freshly roasted at home should be allowed to breathe for the best results. They should be left uncovered overnight.
The next day, they can be sealed in an airtight jar, and they will remain at their fresh for almost one week if stored in a cool, dry place.
However, that at all does not mean that they should be stored in the freezer. The oils can get damaged by extreme cold. The result of which the flavors in your newly roasted coffee beans will also get damaged.
Moreover, since the beans tend to be porous, odors from within the freezer can get absorbed by the beans quite easily.
You barely need anything for oven roasting, and once you get used to it, you will find roasting coffee beans at home as easy as preparing a hot, steaming cup of coffee itself.
