Molecular SO2 effect on Brettanomyces bruxellensis populations during a one-year storage

Molecular SO2 effect on Brettanomyces bruxellensis populations during a one-year storage

This work confirms that B. bruxellensis development can be tempered by SO2 addition if a sufficient molecular concentration of 0.8 mg.L-1 is achieved. However differences do exist among strains in terms of cellular multiplication and cultivability. This in turn has an impact on VP production.

A new device for stabilisation of white wines throughout a continous flow system

Parpinello, G.P., Ricci, A., Serantoni, M., Balducci, A., Ragni, L., Versari, A.; University of Bologna, Italy

Proteins occurring in wine originate from several sources during the winemaking process. Protein content in wines ranges from traces up to hundreds of mg/L, and may cause physical instability in wh...

An electrochemical method for real time measurement of polyphenols during winemaking

By Christine Pascal, Nelly Champeau, Jean Baptiste Diéval, Stéphane Vidal; Vinventions, Enology team, France

Polyphenols are known to play a major role in must oxidation as well as in wine aging and oxidation. However, they are difficult to measure in the cellar due to lack of adequate technology. Therefo...
