Exploration into the Influence of Malolactic Fermentation Parameters and Pre-fermentation Juice Treatment on Chardonnay Mouthfeel

Creator:: Sereni, Anthony
Abstract:: Mouthfeel is one of the most important quality parameters of Chardonnay wines. Malolactic fermentation (MLF) is an important process in wine production, and influential to wine mouthfeel, with the reduction in acidity being particularly important for cool climate wines that generally have higher acidity such as Chardonnay. MLF is typically...
