There is argument over exactly what your roasted beans should look like. Some say the perfect city roast is the beans being just at the beginning of shiny, with no oil showing.
The oil should stay in the bean for the correct flavor to be in the grounds. Oil on the storage container is flavor not in your cup. They say oily beans are a sign of over roasting.
