Potassium metabisulfite is widely used in the wine-making and brewing industries. It prevents the development of unfavourable microflora in fermented musts. Potassium metabisulfite protects wine batches from contamination and eliminates the presence of the so-called wild yeasts.
When used with ready wines, it stops fermentation, stabilises the colour and clarity.
Potassium metabisulfite is also an excellent disinfectant used for rinsing wine-making, brewing or distilling equipment.

Directions for use:
Depending on the application:
1) to stabilise must: 1 g per 10 L of must. Dissolve a proper portion in 50-100 ml of water, add to the must and mix thoroughly.
(2) to stabilise wine before pouring it into bottles: 1 g per 10 L of wine. Dissolve a proper portion in 50-100 ml of water, add to the must and mix thoroughly.
3) to rinse equipment: 10 g per 2 L of water. Use the solution to rinse demijohns, fermentation containers, bottles, presses, barrels that have been washed with detergent and rinsed with water. Do not reuse water after rinsing with potassium metabisulfite.
Potassium metabisulfite solution is unstable and should therefore be prepared just before use. After rinsing, the solution should be discarded. Due to its characteristic, strong sulfuric odour, it is recommended to use the product only in well-ventilated rooms.

Potassium metabisulfite is a common wine or must additive, in which it forms sulfur dioxide gas (SO2). This both prevents most wild microorganism  from growing, and it acts as a potent antioxidant, protecting both the color and delicate flavors of wine. Winemaking equipment is sanitized by spraying with a solution.


Potassium metabisulfite is sometimes used in the brewing industry to inhibit the growth of wild yeasts, bacteria, and fungi. This is called 'stabilizing'. It is also used to neutralize chloramine that has been added to tap water at the source as a disinfectant. It is used both by homebrewers and commercial brewers alike. It is not used as much for brewing beer, because the wort is almost always boiled, which kills most microorganisms. It can also be added to strike water (the water used to mash the malted barley) in order to remove chloramines which can cause phenolic off flavors in beer.
