A Simplified View of Chemical Oxidation Mechanisms in Red Wines and the Role of Sulfur Dioxide

It is well known that wines are negatively affected by oxygen during the aging process, whites even more so throughout winemaking. Oxidation causes color to turn to a brownish color and convert desirable aroma and flavor compounds into flaws, possibly making the wine undrinkable. Sulfur dioxide, or SO2, is used in winemaking partly because of

Using your Vinmetrica analyzer to measure oxygen levels and make greater wines

Measuring and controlling oxygen, and more specifically, dissolved oxygen (DO), throughout the winemaking process should be part of every winemaker’s quality control protocol, much like free sulfur dioxide (SO2) levels. The chemistry of oxygen reactions notwithstanding, home winemakers have been shying away from measuring oxygen because there have not been any affordable, easy-to-use tools. But Vinmetrica
