BDF Sodium metabisulphite 500g

Sodium Metabisulphite is a strong sterilising powder that once dissolved in cold water (where it forms sulfur dioxide gas) will inhibit the growth of mould and bacteria on all surfaces it comes into contact with. Used to sterilise brewing and winemaking equipment and beer and wine bottles.

Sodium Metabisulphate is also a common additive used to preserve and stabilize wines, ciders, and occasionally beers. When added to wine or must, it forms sulfur dioxide gas (SO₂). This prevents most wild microorganisms from growing and acts as a potent antioxidant, protecting both the color and delicate flavors of wine.
