Potassium Metabisulphite is a widely used winemaking agent. It effectively kills wild yeast and bacteria. The condition of your grapes and pH levels may vary the amount needed. This agent helps to clear the way for your yeast, better allowing it to do its job. Sulphites also aid in inhibiting enzymatic browning in white wines, and improves the flavour when used correctly. Metabisulphite does lose potency over time, so you should replace your supply at least annually. If you have some old metabisulphite, it can be used for sanitizing purposes.
