Key brewing benefits

In brewing, gypsum can contribute to water hardness by adding calcium and sulfate. This balance may influence acidity and help proteins settle during the boil, potentially yielding clearer results. A common starting point is 1 teaspoon per 5 gallons of water.

• Raises calcium and sulfate levels to improve mineral balance in soft or distilled water.
• Supports coagulation of proteins during boil for clearer liquids.

Soil, garden, and culinary uses

Beyond brewing, gypsum serves as a soil conditioner and pH reducer, commonly used to boost calcium and sulfur in soil, improve water retention, and support plant health. Traditional tofu production and certain wine, pickle, and canning applications also leverage its mineral balance.

• In soil: increase calcium and sulfur, improve moisture retention, help address blossom end rot.
• In food and crafts: traditional tofu production, wine clarification, pickling, and canning.
