Do sulfites from red wine disapate in cooking?

Sulfites are commonly added to red wine as a preservative to prevent oxidation and microbial spoilage. While some sulfites may dissipate during the cooking process, it's important to note that the extent of their reduction can vary depending on several factors, including the cooking method, temperature, and duration.

Here's an overview of how cooking may affect sulfite levels in red wine:

1. Boiling: Sulfites are water-soluble compounds, and boiling red wine can lead to some evaporation of the liquid, which may result in a slight reduction of sulfite content. However, it's worth noting that boiling may also concentrate other components of the wine, potentially altering its overall taste and aroma.

2. Simmering: Simmering red wine at a lower temperature for a longer period may allow for a more gradual evaporation of sulfites compared to boiling. However, similar to boiling, simmering can also affect the flavor and aroma of the wine.

3. Reduction: Cooking red wine in a sauce, stew, or marinade may lead to some reduction of sulfite levels as the wine liquid is absorbed into other ingredients. The extent of reduction will depend on the ratio of wine to other components and the cooking time.

4. Degradation: At higher temperatures, sulfites may undergo chemical reactions and degradation. This process can be influenced by factors such as the cooking temperature, pH level, and presence of other compounds in the food.

It's important to remember that even if some sulfites dissipate during cooking, individuals with sulfite sensitivities may still experience reactions to red wine in cooked dishes. If you have concerns or sensitivities, it's advisable to consult a healthcare professional or nutritionist for personalized advice.
