Roasting
After green coffee is transported and sold it must be roasted. The coffee is roasted for 11-15 minutes at up to 450°F. During the roasting process the volatile flavor oils develop to a critical point where the variety in their character is released.
Roast Colors
1) Yellow
2) Cinnamon
3) City
4) Chestnut brown
5) Dark
It takes a skilled expert to determine when to stop the roasting process. Once roasting is finished, beans are immediately moved to a rotating tray for cooling and darken one more shade in the next four minutes. Roasted coffee is measured by color and flavor. At this point coffee begins losing its flavor and should be protected from oxygen and moisture. Properly stored, coffee should last about two weeks at peak freshness.
