Brewco Sodium Metabisulphite is a multi-purpose powder for winemakers and brewers: a steriliser for equipment, an antioxidant and preservative for wine and cider, and a way to remove chlorine from brewing water. It's the same active ingredient as Campden tablets, in loose form.

Uses

  • Sterilising equipment, bottles and fermenters
  • Protecting finished wine and cider from oxidation and spoilage bacteria
  • Removing chlorine from tap water before brewing

How to use

For sterilising, coat all surfaces with the solution, then rinse thoroughly. See the How to Use box for wine dosing.

Who it's for

Winemakers and cider makers who want an economical preservative and steriliser. Prefer measured doses? Campden Tablets do the same job in tablet form. Avoid breathing in the fumes when mixing. For no-rinse sanitising on brew day, many brewers use ChemSan instead.
