Fermentaholics Potassium Metabisulfite 2 oz

Fermentaholics Potassium Metabisulfite is a great food preservative and winemaking tool for people who like to make wine and fermented drinks. It’s a strong antioxidant and antimicrobial that keeps wine and other drinks safe. This product is made to protect wine must from oxidation and the growth of bad bacteria, making sure that your wine ferments and ages well.

Fermentaholics Potassium Metabisulfite is easy to use and can be mixed with water to make a cleaning solution or added right to the wine must. It works with the acids in wine or must to release sulfur dioxide, which helps protect wine from bacteria and oxidation. Winemakers can use it in different amounts based on their needs, giving them control over the winemaking process.
