Gypsum – Calcium Sulfate for Brewing Water Adjustment

Gypsum (calcium sulfate) is used in brewing and winemaking to adjust the mineral content of water or must.

In brewing, gypsum increases calcium and sulfate levels, which can improve mash performance and enhance hop character in beer.

In winemaking, gypsum may be used in small amounts to adjust mineral balance during fermentation.

Typical use: Add approximately 1–2 teaspoons per 5 gallons, depending on the desired mineral adjustment.
