How to Roast
If you plan to do some roasting at home, there are some things that you will want to know, if you don’t plan to roast at home, these are still fun items to know. First you will need to heat the beans to about 370F to 500F. The beans have to be in constant motion, and be ready to vent the smoke and deal with chafe that might develop during roasting. Also, be ready to cool the beans quickly when ready to prevent over roasting.
As you roast the beans you will notice them getting darker, going from green to yellow and eventually brown – you might even hear them pop. The popping you hear is the moisture escaping from the bean. As the moisture escapes, the oil from the bean starts to come to the surface and results in a shine on the bean.
What the degree of roast means
Different roasts on your beans will create different tastes. Let’s say that you have a bean that has a very distinct soil that is was grown in and you want to showcase that taste – you would use a light roast. Light roasts allow more of the bean’s flavor to shine through.
As you continue to roast the bean darker and darker the acidity of the bean goes down, and more of the flavor of roast comes through.
Each person has a distinct palate and will enjoy certain beans from various regions over other regions’ beans. Additionally, the roast will also play a large role in making the bean an even better treat. For example, a Sumatran bean often reaches its best flavor with a darker roast, as a light roast its natural flavors are not nearly as noted.
The important thing is to have fun with roasting coffee and to be sure to enjoy and savor your coffee.
