Freshly roasted light roast beans should be dry; dark roast beans should be oily. But surface oil isn’t a perfect freshness indicator.

Ever picked up a bag of coffee beans and wondered whether the oily sheen means it’s fresh—or past its prime? Many coffee drinkers assume that shiny beans are fresh, while dry ones are stale. But in specialty coffee, the truth is more nuanced. Whether your beans look oily or not depends heavily on how they were roasted, not just when.
