How can freshly roasted coffee typically be identified?

Freshly roasted coffee is most commonly identified by its strong aroma and the presence of an oily sheen. When coffee beans are roasted, they undergo a transformation that releases the natural oils within them. This release is what contributes to the rich and inviting aroma that freshly roasted coffee is known for. The oil can also surface on the beans, creating that characteristic sheen.

The strong aroma is a result of countless volatile compounds released during the roasting process, which are responsible for the complex flavors and scents associated with coffee. This makes aromatic quality a key indicator of freshness. In contrast, stale coffee or coffee that has been improperly stored typically lacks this vibrant aroma and sheen, which is why this distinction is critical for coffee enthusiasts and professionals alike.

Other options do not accurately reflect the qualities of fresh coffee; for instance, the presence of a weak aroma and bland taste indicates either older beans or improper roasting, and dry, sheen-less beans suggest lack of freshness as well. The statement about color being lighter is not universally applicable since the roasting process can yield different results based on the desired roast level.
