| sulfur dioxide |
In the form of potassium metabisulfite crystals, liquid sulfur dioxide, or sulfur dioxide gas, sulfur dioxide is an effective and safe preservative, antioxidant, and antimicrobial agent that has been used for millennia to facilitate the winemaking process. It is a respiratory irritant in high concentrations, so it should always be handled with care. Usual levels of free sulfur dioxide in table wines is about 20 to 40 parts per million.

| sulfur dioxide |
a corrosive gas produced both by nature and technology in nearly equal amounts. Burning fuels, such as coal and oil, that contain sulfur produces SO2. It is also produced from sea spray, organic decomposition and volcanic eruptions. When combined with water in the air, it produces a weak, corrosive sulfuric acid -- an ingredient of "acid rain."
