Coffee, originally when in the stage of being a green bean, is extremely hard and bitter in smell and taste. So to transform the coffee from this to the aromatic brown coffee beans, roasting is an essential step. Roasting not only improves the smell and taste but removes toxins from the beans.
Process of Roasting Coffee
The processing of coffee involves the simple five-part process of cleaning, roasting, cooling, grinding and packaging. Roasting is actually done by putting fresh green beans into the roaster, which are vertical or horizontal rotating drums where the coffee beans are passed through hot burning gases. The temperatures are set between 370-540 degree F and the roasting time can vary from 8 to 30 minutes, depending on the type of roasting required.
This process doubles the size of the beans, its density and color. A lighter roast will give you a particular flavor of the region the coffee bean belongs to. The world’s best coffee beans come from Jamaican Blue Mountain, Kenya, Hawaiian Kona and Java. Coffee beans can be roasted up to various degrees to form "Light Cinnamon Roast," “Vienna Roast,” “French Roast” or “Full City Roast.” Every type will have potent taste from the roasting instead of the taste of the soil they came from.
This roasting can be done in either direct or indirect way. The latter is done by not allowing the burner to come in contact with the coffee, even if the gases are in touch with the beans. When the roasting is complete, water sprays are used to smother the beans, only to be passed through “destoner,” removing the wastes that are left to be eliminated. When the beans are passed through the heat, it unlocks the true coffee flavor, by releasing the aromatic oils and burning the carbon dioxide and moisture.
Home Roasting
Up till the 20th century, coffee was roasted in houses only. However, this practice took a back seat, with the new commercial methods of roasting coffee taking over. The various methods followed in home roasting are in pans of cast iron, over fire coals, rotating iron drums over a fire or coal base.
Various Methods of Commercial Roasting
Apart from the above-mentioned process of horizontal or vertical rotating drum, Fluidized Bed and Fast Roasting are two other processes. Coffee beans are exposed to spurts of high paced gas that allows the coffee beans to move in a controlled atmosphere of the Fluidized Bed. For uniform roasting you need to control the momentum of the gas while coming out. On the other hand, fast roasting is another process where the beans are roasted within 4 minutes maximum, which results in high volume and concentration. The roasting process leads to change in the chemical composition of the coffee imparting it a deep smell, dark color and great taste.
