Gypsum, also known as Calicum Sulphate turns “soft” water into “hard” water. Hard water is rich with minerals which some say adds a certain flavor into their brews or spirits.
Home-brewers and home-distillers add the contents into their distilled water to give it some hardness. It fights against toxic substances in the yeast. It also doubles as a way to lower the pH of water. Our Gypsum is in powdered form (also known as hydrated calcium sulphate) and is an essential part of yeast cell formation.
Directions: Use 1 teaspoon of package contents per 5 gallons of water.
