a) 160 mg/l for red wines;
b) 210 mg/l for white and rosé wines;
c) 185 mg/l for quality sparkling wines and VSQPRD
d) 235 mg/l for sparkling wines.
For non-sparkling wines with a residual sugar content, expressed as invert sugar, equal to or greater than 5 g/l, the limits become the following:
a) 210 mg/l for red wines;
b) 260 g/l for white and rosé wines.
1 g of Potassium Metabisulfite provides approximately 5 mg/l of SO2.
