Damascones are rose ketone aroma molecules that have fruity, floral, spicey, and woodsy aspects to them. They are found in roses as well as in other flowers and in some fruits and beverages. They can have facets of berry, plum, apple, rose, honey, tobacco, and blackcurrant. Beta damascone and alpha damascone are found in nature, but delta damascone is synthetic. Beta has more plum/blackcurrant while alpha has more apple.
