Protein haze can appear in white wines during transportation and storage. This instability represents an aesthetic problem that can be prevented by removing the grape proteins that have survived the winemaking process. Matteo Marangon, Associate Professor at University of Padova (Italy), will cover: recent developments in wine protein instability, including the most current version of
A range of volatile sulfur compounds can form in wine, resulting in a variety of unwanted reductive sensory characters. The reductive aromas wine fault is mainly caused by excessive H2S and other volatile sulfur compounds with a negative impact on the wine aroma profile. The most efficient prevention of undesirable reductive aromas in wine lies
Protein haze can appear in white wines during transportation and storage. This instability represents an aesthetic problem that can be prevented by removing the grape proteins that have survived the winemaking process. This instability results in PR-proteins denaturation, and this in turn leads to their aggregation and precipitation, with formation of turbidity and sediments in bottled wines. Winemakers

In the current global warming scenario, wines show flat sensory profiles with high alcohol content, high pH and lack of varietal aroma and freshness. Acidification biotechnologies such as the use of L. thermotolerans help transform sugars into lactic acid by strongly reducing pH and slightly reducing alcohol content. These biotechnological strategies help to improve freshness
