Description
Sodium Metabisulphite is a powder that releases sulphur dioxide when mixed with water. When used in small dosages Sodium Met has an oxygen scrubbing effect and is a popular preservative for wine production.
If using to avoid oxygen pickup in beer, we recommend dosing a 19L corny keg with 0.3g (1/16th of a teaspoon) of Sodium Metabisulphite during packaging.
Caution: Irritant. Use gloves if handling and avoid inhaling any fumes while dosing your wine/beer.
