Calcium Sulphate (Gypsum) - 100g

Calcium Sulfate (Gypsum) – Food Grade – 100g

Top Brew's Calcium Sulfate, commonly known as Gypsum, is an essential brewing salt used to lower mash pH, add calcium, and enhance hop crispness and dryness in your beer. Ideal for soft water profiles, it’s particularly suited to British-style ales, IPAs, and pale ales, where sulfate levels help accentuate hop bitterness and create a clean, sharp finish.

This additive provides both calcium (Ca²⁺) — crucial for yeast health, clarity, and stability — and sulfate (SO₄²⁻), which brings out hop character and balances the beer’s overall flavour profile.

Key Features:

• 100g pack of food-grade Calcium Sulfate (Gypsum)

• Lowers mash pH and enhances hop-forward flavour

• Adds calcium for improved enzyme activity and yeast performance

• Increases sulfate for a dry, crisp, bitter finish

• Ideal for pale ales, IPAs, and English-style beers

• Commonly used to add permanent hardness to brewing water

Brewing Guidance:

• Maintain calcium levels between 50–150 mg/L

• Target sulfate levels between 30–70 mg/L for most ales, or up to 200 mg/L for hoppy beers

• Recommended sulfate-to-chloride ratio:

  • 4:1 – Hoppy beers

  • 1:1 – Balanced flavour

  • 0.5:1 – Malty beers

Usage:
Dissolve small, measured amounts in your brewing water or add directly to the mash. Use a water adjustment tool such as BeerSmith or BrewFather for precise control over your target profile.
