Wine Processing
Wine making is a balance between ancestral tradition and the most advanced technology. Even if flavor of wine is decided by the vine itself, the good management of your process plays an important role in the final quality of your wine. Wine is susceptible to yeast and mold contamination, which may cause off-taste and odor. Microbial management can reduce these risks, by ensuring biological and physicochemical stability as well as organoleptic properties. Detecting these contaminations earlier in the process can significantly reduce the risk of spoiled product released to the market.
While production processes may vary slightly depending on the type of wine you’re producing, the general wine-making process remains the same. Millipore provides you with the tools, technologies and expertise to customize your process, offering total solutions that talk to efficiency, quality and cost effectiveness.

About Wine Processing
Wine Microbial Stabilization
Cold sterile filtration prior to filling contributes to the biological stabilization and improves the quality of the wine.Yeasts from Brettanomyces species are responsible for formation of high quantities of volatile phenols causing unpleasant smelling and affecting flavor: 4-ethyl-phenol and 4-ethyl-guaiacol. These yeasts can originate in the vineyard growing particularly well in wooden elements and barrels during fermentation or aging.
