Product Description

Uses: Potassium Metabisulphite (AKA sulphite) is a white crystalline powder which mixes with water to form a sanitizing solution. It is the most widely used sanitizer in home-winemaking. Sulfites have been utilized in winemaking for hundreds of years. Sulphites also act as a preservative to prevent oxidation in wine.

For Sulphite additions in wine: Dissolve 3 grams (1/2 tsp) per 23 L of wine to give 50 ppm. Dissolve in a small amount of cold water. Stir into wine thoroughly. Seal tightly when not in use.

To make a 2.5% sanitizing solution: Dissolve 50 grams (8 tsp) into 4 L of cold water. This produces a re-useable solution that will last for about 2 months. Keep it tightly sealed in a glass or plastic container only (it will corrode metals). To sanitize simply rinse your equipment and let it drip dry for 10 minutes. The metabisulphite solution can be poured into or on your equipment, or your equipment can be dipped into it. (Helpful Hint: use a spray bottle to spray it onto your equipment).
