Potassium Metabisulfite – 55 lb
Potassium metabisulfite is used as an antioxidant. May be used at modest levels (10ppm free SO2) to provide protection from headspace oxygen.
Potassium metabisulfite: Antioxidant and antimicrobial agent
Our potassium metabisulfite is a high quality white crystalline powder that does not clump. Manufactured in Germany, the 1 kg potassium metabisulfite is packaged with a resealable ZIP-LOK® bag, assuring fresh quality and NOT losing its strength over time if unopened. The 25 kg potassium metabisulfite is packaged in tri-laminate packaging, offering a longer shelf life.
Dissolve potassium metabisulfite in cold water and add directly to must/wine.
100 grams of potassium metabisulfite releases around 57.6 g SO2
To optimize the use of PMBS, we recommend trials prior to the routine use of the antioxidant. This assures optimum protection and uniform beer quality. PMBS is normally added at 10 – 20 ppm is (0.25 to 0.50 lb/100bbl.; 1-2 g/hl) of beer. Maximum addition depends upon application but should not generally exceed 100ppm.
Application rate (malt & grain): 10-20 ppm (0.25-0.50#/100 bbl)
