Molecular SO2 in wine calculator is a free web-based tool that estimates how much free SO2 is required to protect your wine based on its PH. To get perfect and accurate results, use this calculator tool, to use this calculator tool, give the inputs in the input boxes and click on the calculate button.

### What is Molecular SO2 in Wine?

Sulfur is one of the most effective products for making wine as sulfur is a natural byproduct that will be achieved by the fermentation process. If you can see even there will be a small amount of sulfur that you found in bread. There are some recommended levels of sulfur in a variety of wines. They are 0.5 mg/L (ppm) for red wines, 0.8 mg/L (ppm) for white wines, 1.5 mg/L (ppm) for dessert wines.

Molecular SO2 in wine can be calculated by using the formula,

r = a / (1 + 10[p - 1.8])

where,

r = molecular SO2

a = free SO2

p = pH of the wine.

### Steps to Calculate Molecular SO2 in Wine

Go through the guidelines carefully to calculate the molecular so2 in wine easily. Just follow the steps given.

• Note down the values that are given in the problem.
• And then apply the basic formula, r = a / (1 + 10[p - 1.8]).
• Finally, get the result easily by substituting the values and by simplifying it.
