Non-saccharomyces yeast derivatives as bio-adjuvants in the winemaking process. Contributing to the understanding of red wine longevity

Abstract 1

After a short introduction on the different types of yeast derivatives authorized by the Organization International de la Vigne et du vin (OIV), the seminar will focus on the biodiversity of different non-conventional yeast derivatives and the results obtained by using some of them during the winemaking process.

In particular, results on the impact of non-Saccharomyces yeast derivatives on wine protein stability will be shown.

Abstract 2

The seminar will focus on the results of controlled oxygen management experiments carried out on the farm (micro-oxygenation, nano-oxygenation and use of membrane contactors) and in the laboratory (forced oxidation) on red wines with different phenolic compositions. The studies were aimed at understanding the role of sulphur dioxide, anthocyanins, tannins and pH in the evolution of wines in contact with moderate amounts of oxygen, with particular reference to the production and consumption of acetaldehyde.
