Calcium Sulphate - 250g

Calcium Sulphate (In brewing calcium sulphate (gypsum) may be added to brewing water to increase calcium levels. Proper calcium levels in brewing water can:

  • reduce mash pH
  • preserve mash enzymes
  • increase extract yield
  • improve yeast growth and flocculation
  • accelerate oxalate removal
  • reduce colour.

The sulphate ion in calcium sulphate is thought to promote a drier beer, which in turn may allow bitterness and hop flavours and aromas to be more prominent. Adding calcium sulphate to brewing water is common when brewing pale ales and India pale ales.

Before adding salts to your brewing water you should obtain a water analysis report to enable you to calculate the amount of salts in your brewing water after making any additions. Refer to the Brewing Resources page for some links to water chemistry calculators.
