The term bouquet (Engl. "flower bush", also known as bouquet, flower or nose) has only been used in connection with a wine appeal since the beginning of the 19th century as a supplement to aroma. In most cases, this is understood to mean the smell or scent of a mature wine after bottle-ageing. This is why bouquet is also called tertiary aroma or storage bouquet. However, it is also the sum of all olfactory and gustatory substances in a wine. However, experts disagree on the transition from aroma to bouquet during wine development; see aroma and aroma substances.
