DescriptionHydrogen sulfide (H2S) is a powerful aroma compound largely produced by yeast during fermentation. Its occurrence in wines and other fermented beverages has been associated with off-odors described as rotten egg and/or sewage. In wine fermentations, H2S is largely formed by reduction of exogenous sulfate during the biosynthesis of the sulfur-containing amino acids cysteine and methionine. Sulfite, which is commonly added to grape musts as an antioxidant and antimicrobial agent, can also enter the cell and become a source of H2S, after reduction by sulfite reductase.
