Definizione

A substance present in wines obtained from alcohol oxidation; it affects wine flavour, aging and colour. 1

Nota

Aldehydes are carbonyl compounds distinguished by the terminal location of the carbonyl functional group (- C=O). […]
Grapes produce few aldehydes important in the generation of varietal aromas. This may result from their reduction to alcohols during fermentation. […] However, most aldehydes found in wine are produced during fermentation, processing, or extracted from oak cooperage. 2

Contesto

[…] The method provides the opportunity to monitor individual aldehyde levels in wine during fermentation and aging and to evaluate the effects that aldehyde formation may have on wine flavor. 3
