Pre-fermentation cold soak is a winemaking technique used to alter the color, mouthfeel, and aroma of red wine. While it is still debated what impact cold soak has on these wine quality parameters, current thoughts are that resident yeast populations found in fresh grape must play a role in altering...
Cold soaking is a technique used during red winemaking to alter the aroma, flavor, and phenolic content of a wine. However, cold soaking does not come without risk, as this process can result in the production of spoilage compounds such as acetic acid and ethyl acetate if excessive growth of...

Reductive sulfate assimilation, the biological process by which sulfur-containing amino acids and key derivatives are synthesized from sulfate, is broadly shared among bacteria, fungi, and plants. It is the major, if not sole source of methionine and cysteine for Saccharomyces cerevisiae during wine fermentation. Two obligate intermediates formed in the...
