Labels on wine containing more than how many ppm of SO2 must declare "Contains Sulfites"?

The requirement for wine labels to state "Contains Sulfites" arises from regulations aimed at protecting consumers who may have sensitivities to sulfur dioxide (SO2), which is commonly used as a preservative in wine. In the United States, the threshold for this labeling mandate is set at 10 parts per million (ppm).

When the SO2 content in the wine exceeds this level, the label must inform consumers about its presence. This is important because some individuals may have allergies or sensitivities to sulfites, and being aware of their presence can help these consumers make informed choices about their wine consumption.

Understanding this regulation is essential for anyone involved in the wine industry, as accurate labeling not only complies with legal requirements but also promotes transparency and consumer safety. Therefore, the identification of 10 ppm as the critical threshold is key in discussions about wine labeling and its implications for public health.
