How can we reduce the use of Sulphur dioxide in winemaking without compromising its quality?
Fernando Zamora - Universitat Rovira i Virgili, Tarragona (Spain)
The presentation "How can we reduce the use of Sulphur dioxide in winemaking without compromising its quality?" is an overview of the strategies that can be adopted to reduce the use of SO2 in winemaking, even in presence of the effect of climate change. The rationale use of new scientific knowledge and of several innovations can allow to reduce to a minimum the sulphite addition or even to totally avoid its use at least in some phases: biocontrol tools, physical treatments, complementary additive and processing aids, are nowadays available. Some best strategies of prevention of microbial and oxidative phenomena are described.
Fernando Zamora is full professor of the Faculty of Oenology of the University Rovira i Virgili in Tarragona (Spain). He is currently the director Experimental Winery of the Rovira i Virgili University and president of the Technology Commission of the International Organisation of Vine and Wine (OIV)

Wine is fundamentally a high-intervention product, and along all stages from harvest to bottling it's our job to guarantee safety and quality, but it's also up to us to research, experiment, and ad...
Producing a wine according to our oenological objective, wanting to express the variety, but adapting practices according to the sanitary status of the grapes, is continuous experimentation. We aga...
Phenolic composition of grapes has an important impact on the final intrinsic quality of (red) wines. Wine taste, mouthfeel and colour are driven principally by phenolic compounds present in grapes...
