Sodium Metabisulphite - 500g

Sodium Metabisulfite is a granulated powder that releases sulfur dioxide when dissolved in a liquid. It is added in small doses directly to fresh juices 24 hours before adding yeast. This is to destroy any wild mould and bacteria that may have been on the fruit.

Sodium Metabisulfite is also used in stronger doses with water as an equipment sanitizer. You can use it to sanitize fermenting vessels, hydrometers, bottles, hoses or any other glass, metal, plastic or wood that comes into contact with your beer or wine. Each 1/16 teaspoon of Sodium Metabisulfite and will impart approximately 55 parts-per-million (p.p.m.) of sulfur dioxide (SO2) to each gallon of liquor. Each gram will impart 175 p.p.m. to each gallon of liquid.

If you are putting a dose of sodium metabisulphite into your 19L kegs of beer then we would recommend using 0.3grams into the beer and this will greatly improve the shelf life of the beer especially for light coloured beers.

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

This product sterilises (sanitises) but does not clean.  Equipment should be clean prior to using this product.  The dosage rate is 1 tablespoon per 5 liters of water.  Allow the solution to touch all surfaces. This dilution rate is for sterilising of equipment only.

Note: Sodium metabisulphite is used in some instances as a preservative, however, you should follow food application laws exactly and obtain information regarding its use from food safety authorities.
