Calcium Sulphate (Gypsum) 500g

Calcium Sulphate (Gypsum) 500g is an essential brewing water treatment used by home brewers and professional brewers to adjust water chemistry and fine-tune beer flavour profiles. By increasing both calcium and sulfate levels, gypsum helps create ideal brewing conditions while enhancing the crisp, clean bitterness found in many hop-forward beer styles.

Water chemistry plays a vital role in brewing, influencing mash efficiency, fermentation performance, flavour balance, and overall beer quality. Calcium Sulphate (Gypsum) 500g is commonly added when brewing with soft water or when a recipe requires additional calcium and sulfate content to achieve a specific water profile.

One of the primary benefits of gypsum is its ability to lower mash pH. Maintaining the correct mash pH can improve enzyme activity, increase extraction efficiency, and contribute to a cleaner flavour profile in the finished beer. The calcium component also supports yeast health, protein coagulation, and improved beer clarity.

The sulfate portion of Calcium Sulphate (Gypsum) 500g helps accentuate hop bitterness and contributes to a dry, crisp finish. This makes gypsum particularly popular for Pale Ales, IPAs, and traditional British beer styles where hop character is a defining feature.

Historically, gypsum became famous through the brewing waters of Burton-on-Trent in England, where naturally high sulfate levels helped create the distinctive bitterness and character of classic English Pale Ales. Today, brewers often use gypsum to replicate these traditional water profiles and enhance modern hop-forward beer styles.

Whether you’re building a custom water profile, improving soft water, or chasing the perfect IPA bitterness, Calcium Sulphate (Gypsum) 500g is an important tool for achieving better brewing results.

Water Chemistry Information

Calcium (Ca)

Calcium is one of the most important minerals in brewing water and contributes to:

• Improved mash efficiency
• Better yeast performance
• Enhanced protein coagulation
• Improved beer clarity
• Reduced mash pH

Sulfate (SO₄)

Sulfate helps enhance hop bitterness and create a crisp, dry beer profile.

Typical sulfate levels:

• 10–50mg/L for lighter beers
• 30–70mg/L for most ales
• 100–150mg/L for hop-forward styles
• Higher levels for Burton-style ales

Adjusting Brewing Water

Brewers commonly use Calcium Sulphate (Gypsum) 500g alongside other brewing salts to achieve target water profiles.

Common brewing water additions include:

• Calcium Sulphate (Gypsum)
• Calcium Chloride
• Magnesium Sulphate (Epsom Salt)
• Baking Soda
• Chalk
• Table Salt

Using a brewing water calculator can help accurately determine the correct dosage required for your desired beer style.
