The Influence of Lees
Industry Seminar – Winemaking
Aging wine on yeast lees can have a significant impact on aroma and mouthfeel properties. These effects may be a direct consequence of the release of cellular components from yeast during the self-digestion process known as autolysis but these changes can also arise from the oxygen-consuming capacity of the yeast lees. This session will cover these aspects of lees aging and also offer a practical guide to managing lees in the winery.
