Category: Sulfite sensitivity

According to the U.S. Food and Drug Administration (FDA), about 1 in 100 people are sensitive to sulfites, a group of compounds that includes sodium metabisulfite. This common preservative is added to a wide range of foods to prevent spoilage and discoloration, making it crucial for sensitive individuals to know which products contain it.

While all wines contain naturally occurring sulfites, the quantity can vary dramatically depending on the wine's characteristics. Generally, sweeter white wines and less acidic white wines are among those which wines are high in sulfites, requiring extra preservatives to prevent spoilage.

According to the Food and Drug Administration (FDA), all wines containing 10 parts per million (ppm) or more of total sulfites must have a "Contains Sulfites" label. While some assume popular brands like Barefoot Wine are sulfite-free due to their widespread availability, this is not the case.
