• Active ingredient: potassium disulfite (E224)
• Dosage for sulfiting: approx. 10 g/hl or as required
• Airlock barrier liquid: plain water during fermentation; for storage, dissolve 1 g in 50 ml of water (large airlock: 2 g in 100 ml), without acid. This gives a potassium metabisulfite solution of about 2 %, i.e. about 1 % SO₂. Never let potassium metabisulfite come into contact with acid, not even in the same container: toxic gas is released.
