Specific fragrances and scents that allow a product or brand to be associated with a unique sensory experience are known as olfactory signatures. They play a crucial role in helping users remember their interactions with a product or brand. A well-defined and pleasant olfactory signature can strengthen customer loyalty. Conversely, if the scent is more generic, it is considered generic. These characteristic scents are an integral part of a company’s identity and brand image. In the hospitality industry, there are various examples of olfactory signatures that contribute to creating a unique and memorable atmosphere for guests.
