  • Sulfur Dioxide Measurement and Overestimation in Red

    Apr 26, 2019To compare, SO2 values in red wine reported for the HS-GDT method ranged from 30-60% lower than commonly used methods to measure SO2. Currently, it’s recommended to target lower molecular SO2 (0.2-0.3 mg/ L) for dry reds if using the headspace method. Further investigation to validate these recommended targets is still needed.
