SO2 Addition Calculator

Formula

The formula to calculate the SO2 Addition is:

\[ SO2 = \frac{V \times C \times D}{1000} \]

Where:

\( SO2 \) is the amount of sulfur dioxide to be added (in grams).
\( V \) is the volume of wine (in liters).
\( C \) is the desired concentration of SO2 (in mg/L).
\( D \) is the dilution factor of the SO2 solution (usually 1 if using pure SO2).

Example

Let's say the volume of wine (\( V \)) is 100 liters, the desired concentration of SO2 (\( C \)) is 50 mg/L, and the dilution factor (\( D \)) is 1. Using the formula:

\[ SO2 = \frac{100 \times 50 \times 1}{1000} = 5 \text{ grams} \]

So, the SO2 Addition is 5 grams.

What is SO2 Addition?

SO2 addition refers to the process of adding sulfur dioxide (SO2) during winemaking. This is done to prevent oxidation and maintain the color, flavor, and stability of the wine. It also has antimicrobial properties, helping to prevent spoilage from bacteria and yeast. The amount of SO2 added must be carefully controlled as excessive amounts can lead to negative effects on the wine’s taste and aroma.
