Gypsum 100g (Calcium Sulphate)
In home brewing, gypsum (calcium sulphate) plays a key role in adjusting water chemistry to enhance beer quality.
Raises calcium levels, which supports yeast health and fermentation.
Increases sulphate content, sharpening hop bitterness and making flavours crisper—especially useful for hop-forward styles like IPAs.
Lowers mash pH, improving enzyme efficiency during mashing and aiding sugar extraction from grains.
Promotes a cleaner, drier finish in beers.
Helps replicate the water profiles of famous brewing regions (e.g., Burton-on-Trent for pale ales).
Typically added during the mash or boil phase.
Dosage depends on your local water profile and beer style. A common starting point is 1 teaspoon per 5 gallons, but testing your water and adjusting accordingly is ideal.
A brewing additive to compensate water deficiencies for beers.
Also a perfect aid in Sherry fermentation.
Common name for calcium sulphate.
