The herbaceous (vegetative) character of wine can be sensorially pleasant or not depending on different circumstances. This character can be specific to a particular grape cultivar (an endogenous varietal character) or produced during the winemaking procedure, from either an endogenous or exogenous cause. Several volatile wine components containing oxygen (aldehydes and alcohols with 6 carbon atoms), nitrogen (alkylmethoxypyrazines), and selected sulfur compounds (thiols, sulfides, disulfides) are reviewed and described. The effects of micro-oxygenation and storage in wood on the herbaceous post-fermentative character are discussed. Finally, the preventive tools and winemaking technologies used to reduce or to control this sensory character are described.

Abstract
The herbaceous (vegetative) character of wine can be sensorially pleasant or not depending on different circumstances. This character can be specific to a particular grape cultivar (an endogenous varietal character) or produced during the winemaking procedure, from either an endogenous or exogenous cause. Several volatile wine components containing oxygen (aldehydes and alcohols with 6 carbon atoms), nitrogen (alkylmethoxypyrazines), and selected sulfur compounds (thiols, sulfides, disulfides) are reviewed and described. The effects of micro-oxygenation and storage in wood on the herbaceous post-fermentative character are discussed. Finally, the preventive tools and winemaking technologies used to reduce or to control this sensory character are described.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
