Terpenoids and their role in wine flavour: recent advances

Terpenoids and their role in wine flavour: recent advances The terpenoids are a major class of natural products with a range of functions in plants. In the grape, monoterpenes, sesquiterpenes and C13‐norisoprenoids are present either in a free volatile form, or bound to sugars and rendered non‐volatile. Of the many terpenoids in grapes, only a relatively small number makes an important contribution to wine aroma. This review summarises new developments in understanding terpenoids, including the monoterpenes linalool, cis‐rose oxide, 1,8‐cineole and wine lactone; the sesquiterpene rotundone; and the C13‐norisoprenoids β‐damascenone, β‐ionone, 1,1,6‐trimethyl‐1,2‐dihydronaphthalene and (E)‐1‐(2,3,6‐trimethylphenyl)buta‐1,3‐diene.

Abstract

The terpenoids are a major class of natural products with a range of functions in plants. In the grape, monoterpenes, sesquiterpenes and C13‐norisoprenoids are present either in a free volatile form, or bound to sugars and rendered non‐volatile. Of the many terpenoids in grapes, only a relatively small number makes an important contribution to wine aroma. This review summarises new developments in understanding terpenoids, including the monoterpenes linalool, cis‐rose oxide, 1,8‐cineole and wine lactone; the sesquiterpene rotundone; and the C13‐norisoprenoids β‐damascenone, β‐ionone, 1,1,6‐trimethyl‐1,2‐dihydronaphthalene and (E)‐1‐(2,3,6‐trimethylphenyl)buta‐1,3‐diene. Their origin, formation and behaviour during winemaking and ageing, and viticultural influences on their concentration, will be discussed, as well as their role in different wine styles.
