Potassium Metabisulphite 100gr

Potassium Metabisulphite 100gr

High purity potassium metabisulfite. Essential additive in oenology, protects musts and wines from oxidation, eliminates unwanted microbial flora, solubilizes the phenolic substances contained in the skins and blocks the activity of oxidative enzymes. 


The most common form of Metabisulfite is as a powder which is fixed with potassium or sodium. 1/4 tsp of Potassium Metabisulfite adds 50ppm to 5 gallons of must. Old Metabisulfite loses potency with time and should be replaced every year to assure that you are getting correct levels. You can use old Metabisulfite to make solutions for sanitizing equipment.
