Abstract (EN): A sulfur compound not yet studied in alcoholic beverages was found in some wines. It has been revealed in ethyl acetate extracts of wine analyzed by GC/FPD. Its identification was made by its retention time and by GC/ MS. The compound itself has no specific odor, but is a precursor of a very unpleasant poultry-like aroma, 2-mercaptoethanol. The analysis of several hundred wines coming from France, Portugal, and Spain, showed that the bis(2-hydroxyethyl) disulfide content may reach 3500 mu g/L, particularly in the case of wines from Vitis labrusca or its hybrids. More than 5% of the wines analyzed contained more than 200 mu g/L.
