Sulphite-free organic additives to be used in white wine-making process

Ziel

For many years winemakers have been trying to solve the sulphites problem, but. at present time,there is no method or technology that enables to produce wine with very low added sulphitescontent.This proposal addresses the ever more growing requirement of a wine with a very smallconcentration of volatile sulphites. Such an increasing demand concerns a small part of thepopulation, the sulphite sensitive people, but it is expected to spread among the entire population inthe next 2 years.The SULPHREE project proposes to develop a new product for wine processing based onvegetal extracts. This product will be able to mimic the effect of the SO? in white wine makingprocess, thus guaranteeing the antioxidant and antibacterial action. The use of such a product willdecrease the amount of added sulphites during vinification and to obtain, as final result, aconcentration of volatile sulphites lower than 10 ppm in white wines.This proposal wishes to satisfy the requirement for wines with low added-sulphites which isnowadays growing among the sensitive-sulphites consumers worldwide and which, as expected,will increase also among European no sensitive-sulphites people when since 2005, all Europeanwines producers, will be obliged to label wines containing more than 10 ppm of volatile addedsulphites.The main innovative element of the project will be:- the development of a new natural product able to substitute partially SO? in the preservation of white wines,- The setting up of a new procedure to be used at industrial level for reducing by, at least, 75 % the sulphites concentration in/mal white wine- The development of a new methodological tool for winemakers enabling for obtaining safer white wine with high quality standard
