Roast Defect

A problem with the roasting machine or process, resulting in off flavors in the cup: Roast defects indicate a problem with the roasting machine or process, resulting in off flavors in the cup. These are distinct from flavor defects that are a result of green coffee processing, or other factors from the plant itself. While roasting cannot make bad coffee good, it can easily make good coffee bad! Roast defects are sometimes characterized by a lack of sweetness, whether that be caramel, sugar, chocolate, syrup, etc.
