Sodium Metabisulphite is used to make up a sterilising solution for equipment, bottles, and containers. Mix approximately 1 teaspoon per litre of water, use to coat all surfaces of your equipment, then rinse thoroughly before use. A reliable, economical sterilising option for home brewers and wine makers.
Also used in wine making to inhibit bacterial growth and prevent oxidation, in conjunction with Campden Tablets. Always rinse equipment thoroughly after use. See also: Young's Cleaner/Steriliser and Puriclean for alternative sterilising options.
