How To Roast Coffee Beans With Flavor

Many factors such as varieties, origins, altitude, type of soil, farming, processing, and brewing affect how your coffee tastes in your cup. However, if we were to specialize in one factor that features a huge influence on the flavors you enjoy, it might be the roasting of coffee beans.

The coffee roasting process requires intimate knowledge of the ingredient, a trained palate, creativity, discipline, passion, and an understanding of coffee chemistry and the science of heat and energy of cooking. Today, roasting coffee beans is considered both an art AND a science.

Homework before the coffee berry roasting process begins, a roaster has got to do his homework. He needs to know all about the beans to roast right down to the variability, type and flavor note it's going to have. This enables him to make a roasting profile that will best highlight the distinct qualities of every bean. Once this is often done, it's time to roast!

When harvested the coffee beans remain green during the wet process and contain approximately 12% water which needs to be dry before roasting.

Many chemical changes happen to the beans, greatly affecting their aroma and flavor. Roasting duration is extremely crucial to avoid the coffee beans turning acidic or the sugars will over-caramelize. The roaster’s experience and skill will determine the roasting duration thereby creating their unique roasting flavor.

The beans are allowed to de-gas in a container with a one-way valve for about 15 to 24 hours that allows gas to escape. Here the beans fully develop their flavor before they're prepared for brewing.
