how much so2

0.8 mg/l of molecular SO2 is considered the needed amount for white wine and 0.5 mg/l for red wine. Certain "free" SO2 levels are needed to insure the target amounts of molecular SO2 are maintained. It's important to note that the amount of "free SO2 to add to maintain the proper molecular level is dependent on the wine's pH.

    Apr 02, 2019SO 2 emissions that lead to high concentrations of SO 2 in the air generally also lead to the formation of other sulfur oxides (SO x).). SO x can react with other compounds in the atmosphere to form small particles. These particles contribute to particulate matter (PM) pollution. Small particles may penetrate deeply into the lungs and in sufficient quantity can contribute to health problems.

    SO 2 is used as a preservative to protect grape juice, must or wines from oxidation and microbial spoilage. When SO 2 is added, part of it reacts with different components present in the grape juice/must or wine to bound and become inactive as an antioxidant and antimicrobial agent. What remains is the Free SO 2 and is in two parts bisulfite (HSO 3-) and molecular SO 2.
