You stop the roasting process when the beans are 200 degrees worm, when you make light roasted coffee. Light roasted coffee is more fresh and sour than other types of roasting.

The medium coffee roasting stops at approximately 210 degrees. This type is not as fresh as light roasted coffee, but can be sweeter.

Dark roasted coffee is about 225 degress worm when the roasting process stops. The coffee will normally be bitterer. Dark roasted coffee are primarily used for espresso blends.

Light roast coffee will stop processing when the beansareapprox.200 degree heat. Light roast coffee is more fresh and sour.
