Calcium Chloride 500g is one of the most widely used brewing salts for adjusting water chemistry and improving beer flavour. By increasing both calcium and chloride levels in brewing water, it helps brewers create fuller-bodied beers with enhanced malt character, improved mouthfeel, and balanced flavour profiles.

Water chemistry plays a critical role in brewing performance and the final character of a beer. Calcium Chloride 500g is commonly used to increase calcium levels, which contribute to several important brewing processes. Calcium assists yeast health during the lag phase, supports enzyme activity in the mash, promotes protein precipitation during the boil, and contributes to improved beer stability and clarity.

The chloride component of Calcium Chloride 500g is highly valued for its ability to enhance malt sweetness, body, and mouthfeel. This makes it particularly useful when brewing malt-forward styles such as Lagers, Porters, Stouts, Brown Ales, and New England IPAs where a softer, fuller flavour profile is desired.

One of the most important concepts in modern water chemistry is the sulfate-to-chloride ratio. Adjusting chloride levels allows brewers to influence how flavours are perceived in the finished beer. Higher chloride levels generally promote malt character, fullness, and sweetness, while higher sulfate levels tend to emphasise hop bitterness and dryness.

Because of this flexibility, Calcium Chloride 500g has become an essential water treatment for brewers seeking precise control over flavour balance and water profile adjustments.

Whether you’re building a custom water profile, improving soft water, or enhancing mouthfeel in hop-forward or malt-driven beers, Calcium Chloride is an important tool for producing better beer.

Water Chemistry Information

Calcium (Ca)

Calcium contributes to:

• Permanent water hardness
• Improved mash performance
• Better yeast health
• Protein precipitation during the hot break
• Enhanced beer stability and clarity

Preferred brewing range:

• 50–150mg/L

Chloride (Cl)

Chloride helps enhance:

• Body
• Mouthfeel
• Malt sweetness
• Perceived fullness

Higher chloride levels generally favour malt-forward beers and softer flavour profiles.

Sulfate-to-Chloride Ratio

The balance between sulfate and chloride significantly impacts beer flavour perception.

Malt-Focused Ratios

• 1:2 Sulfate to Chloride
• 1:3 Sulfate to Chloride

These ratios help enhance:

• Malt flavour
• Sweetness
• Mouthfeel
• Fullness

Hop-Focused Ratios

• 2:1 Sulfate to Chloride
• 3:1 Sulfate to Chloride

These ratios help enhance:

• Hop bitterness
• Dryness
• Hop flavour and aroma

Adjusting Brewing Water

Brewers commonly use Calcium Chloride 500g alongside other brewing salts to achieve specific water chemistry targets.

Common brewing salts include:

• Calcium Chloride
• Calcium Sulphate (Gypsum)
• Magnesium Sulphate (Epsom Salt)
• Calcium Carbonate (Chalk)
• Calcium Hydroxide (Slaked Lime)
• Baking Soda

Using brewing software such as BrewFather can help determine the correct addition rates for your water profile and beer style.
