SO2 Aspiration/Oxidation Method
Details: This is a simple calculation of SO2 for the aspiration/oxidation method. Whether free, bound or total SO2 is calculated depends on the method you used.
Red Wines: Much of the 'free' SO2 in red wines is actually pigment (anthocyanin) bound - actual free SO2 levels will be very significantly lower.
The following formula is used:
SO2 = ( t * m * 1.6 * 1000 * 20) / v
m = molarity of NaOH
t = titre of NaOH required (mL)
v = volume of sample used (mL)
