Answer From Expert Roger Bohmrich MW
Sulfites as sulfur dioxide occur naturally in wine as a result of fermentation, brought about by the metabolism of yeast. SO2 is also the oldest and most common additive in wine production, having been used by ancient Egyptian, Greek and Roman winemakers, and universally in contemporary winemaking. Sulfur dioxide has many practical benefits, notably its antioxidant and antimicrobial properties, and is also widely used to disinfect equipment. 99% of all wines contain sulfites at varying concentrations. A very small percentage of individuals are sensitive to sulfites, although many more may believe that they suffer ill effects due to sulfites rather than other causes. Sulfite-free wines are certainly critical for asthmatics and other highly sensitive people, but it is difficult to argue that they are superior in terms of taste or stability.
