A scratch-and-sniff coating is provided comprised of a first coating on a substrate having a water- and heat-resistant second coating thereon, the first coating being comprised of a non-encapsulated flavor/fragrance component and a polysaccharide component, and the second coating comprised of a shellac component. The scratch-and-sniff coating is made by forming a first coating comprised of a non-encapsulated flavor/fragrance component and a polysaccharide component and drying the first coating, and forming a water- and heat-resistant shellac-containing second coating on the first coating, and drying the second coating. An encapsulated flavor/fragrance component may optionally be present in the first coating. The scratch-and-sniff coating can be applied to a package for a consumer article.
