Varietal thiol precursors in Gewürztraminer: effect of clone and grape ripening.
, 2017 Much research has been carried out since the discovery of glutathionyl- (GSH-) and cysteinyl (Cys-) precursors of 3-mercaptohexan-1-ol (3MH) in grapes and juices (Tominaga et al.,1998; Peyrot des Gachons et al., 2002) in order to understand the origin of these precursors and optimize the technological options useful to liberate and maintain the free ...

The impact of some clarifying agents on the precursors of the varietal thiols in juice
, 2014 3-S-cysteinyl hexan-1-ol (Cys-3MH), 3-S-glutathionyl hexan-1-ol (GSH-3MH) and 4-S-cysteinyl-4-methylpentan-2-one (Cys-4MMP) are precursors of the so-called varietal thiols responsible for the tropical fruity notes produced during fermentation by some yeast strains having lyase activity.

Impact of organic viticulture on the genesis of varietal thiols in Côtes de Gascogne wines
, 2022 Varietal thiols (3-sulfanylhexan-1-ol, 3SH and its acetate, 3SHA) are powerful aromas that give grapefruit and passion fruit notes to certain wines. These aromatic notes and their power make the typicality of Côtes de Gascogne wines. In this appellation, the evolution of practices towards organic viticulture has highlighted technical obstacles to the ...

, 2023 The use of copper as the only fungicide in organic practices against downy mildew raises again the question of the effect of copper on varietal thiols in wine, especially 3- sulfanylhexan-1-ol (3SH) and its acetate (3SHA). Several works indicated that the use of copper in the vineyard had a negative effect on the content of varietal thiols in Sauvignon
