aroma
In wine parlance, the established definition of aroma is the simple, fruity smell of the grape variety. Today’s broader definition combines a wine’s varietal fragrance plus any changes that develop during fermentation and aging. The traditional difference is that a young wine will show its varietal aroma in a more pronounced way. Whereas in a mature wine—where some of the grape’s intrinsic fragrance has been replaced by other characteristics—the smell transmutes into a bouquet. See also nose.
