Sodium Metabisulphite - 100g
Also known as campden powder is a long-established multipurpose homebrewing ingredient.
Sodium metabisulphite can be used in several ways, the first being used for sterilising equipment. (not a cleaner)
The second use is for purifying/suppressing unwanted bacteria and 'wild' yeasts before a fermentation.

For preserving wine it is recommended to use it in conjunction with potassium sorbate.
To create a sterilising solution add 12.5g (approx 2tsp) per 1 litre of cold water.
