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 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 anyway.

Potassium metabisulfite is a common wine or must additive, where it forms sulfur dioxide gas (SO₂). This both prevents most wild microorganisms from growing, and it acts as a potent antioxidant, protecting both the color, and delicate flavors of wine.

Typical dosage is 1/4 tsp potassium metabisulfite per 6 gallon bucket of must (yielding roughly 75 ppm of SO₂) prior to fermentation, and 1/2 tsp per 6 gallon bucket (150 ppm of SO₂) at bottling.
