Potassium Metabisulfite – 1 lb

Description

Potassium Metabisulfite (often referred to as “SO2” “sulfites” “meta” or “meta bi”) has several uses in winemaking. At the crush sulfites are generally used to help control the spoilage bacteria and indigenous yeast that may already be present both on the fruit and in the winery (i.e. on the picking bins processing equipment tanks tubing etc.). The amount generally used is enough to inhibit most of the unwanted organisms but not enough to hinder a cultured yeast which has a higher tolerance to sulfites than most of the indigenous organisms do. This inhibition effectively “wipes the slate clean” for the cultured yeast to step in and rapidly colonize the must so that it can effectively dominate the subsequent fermentation. In addition sulfites also help to inhibit the enzymatic browning of both musts and finished wines so that all of their delicate complexities can be preserved. Later during storage and in the bottle sulfites at the proper levels will further protect a wine by continuing to inhibit spoilage organisms as well as by scavenging oxygen. Note that the exact amount needed to effectively do the job is determined by the pH of the wine. In addition it’s important to keep in mind that free SO2 levels fall faster in wood cooperage than in glass or stainless so if you are using a barrel you will most likely need to manage sulfite levels more closely. The most common form of Metabisulfite is as a powder which is fixed with potassium or sodium. 1/4 tsp of Potassium Metabisulfite adds 50 ppm 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.
