E224 - Potassium metabisulphite

Potassium metabisulphite (E224) is a sulphite-based preservative and antioxidant used to keep foods and drinks fresh. It releases small amounts of sulphur dioxide that slow browning and help control unwanted microbes in products like wine, fruit products, and some soft drinks.

  1. How much potassium metabisulfite per gallon of wine?

    About 0.3 g per US gallon (≈50 ppm as SO2), or 1 Campden tablet per gallon; adjust to wine pH and confirm with a free SO2 test.

  2. How much potassium metabisulfite per gallon of mead?

    Start with ~0.3 g per US gallon (≈50 ppm as SO2), or 1 Campden tablet per gallon; mead’s typically higher pH may require more to reach the target molecular SO2, and stabilization often also uses potassium sorbate.

  3. Is potassium metabisulfite harmful?

    At permitted food levels it’s generally considered safe, but sulfites can trigger asthma or allergic‑like reactions in sensitive individuals; the powder/solutions are irritating, so avoid inhalation and skin/eye contact.

  4. When to add potassium metabisulfite to wine?

    Add at crush to limit wild microbes and oxidation, then maintain appropriate free SO2 after fermentation during aging/racking and just before bottling based on pH.

  5. How much potassium metabisulfite per gallon?

    About 0.3 g per US gallon (≈50 ppm as SO2), or 1 Campden tablet per gallon; measure free SO2 and adjust for your beverage’s pH.
