  • What are Tannins?

    • Tannins are natural compounds found in the skins, seeds, and stems of grapes. They contribute to the bitterness, astringency, and complexity of wine.
    • Some research suggests that excessive consumption of tannins may contribute to health issues such as digestive problems, particularly in individuals with sensitive stomachs or gastrointestinal conditions.
    • Tannins can also interfere with the absorption of iron, which may be a concern for individuals with iron deficiency anemia.
  • What are Sulfites?

    • Sulfites are commonly used as preservatives in wine to prevent spoilage and oxidation.
    • According to the FDA, sulfites can cause allergic reactions in some people, particularly those who are sensitive to sulfites. Symptoms may include hives, itching, flushing, or even anaphylaxis in severe cases.

  • Other Considerations

    • The combination of sulfites and tannins in wine may exacerbate symptoms in individuals who are sensitive to either compound.
    • Red wines generally contain higher levels of tannins compared to white wines, which may be a consideration for those who are particularly sensitive.
    • It's important to note that moderate consumption of wine, which typically contains relatively low levels of sulfites and tannins, is generally considered safe for most people and may even offer some health benefits due to the presence of antioxidants such as resveratrol.
