What does sulfur mean to wine?
The sulfur both protects the wine from unwanted development and allows the wine to grow old gracefully. In an ordinary situation, the sulfur will break down over time in bottle, so an older wine will typically have less perceivable, or free, sulfur.
Why is sulfur dioxide used in wine making?
Sulfur Dioxide (SO2) is the most common chemical compound used in winemaking. Sulfur serves two main purposes. It prevents the wine from reacting with oxygen which can cause browning and off-odors (oxidation), and it inhibits the growth of bacteria and undesirable wild yeasts in the grape juice and wine.
