All About Coffee

Why Grind Your Own Coffee

The most important step in getting coffee into your cup is the roasting. Roasting coffee is both an art and a science, requiring years of experience and the right type of roasting equipment.

Green coffee beans are roasted at temperatures ranging from 370 to 450 degrees for up to 20 minutes. During this time they lose 18 to 23% of their weight and increase in size by 35 to 60%. They change color from a light straw green color to medium brown or dark brown, depending upon the degree of roast. The bean splits open and brings out the rich aroma of the coffee.

Roasting is merely the "cooking" of the bean. How much the bean is roasted is what is called the degree of roast. The less it is cooked, the "lighter" or "milder" the roast. There are different terms used for the degree of roast. Some use the words Mild - Mild-Medium - Medium - Medium-Dark - Dark.

Today, another common naming of roasting is after countries -- American roast, French roast, Italian roast, Turkish roast. These all go from light to dark, from mild in taste to downright burnt tasting.
