Calcium Sulfate (Gypsum) – Brewing Water Adjustment

Enhance Hop Perception and Improve Brewing Water Profiles

Calcium Sulfate, commonly known as Gypsum, is a vital brewing salt used to adjust water chemistry for better beer flavor, mouthfeel, and clarity. Available in both 2 oz and 1 lb sizes, this powdered form of gypsum is ideal for dialing in your water profile, particularly when brewing hop-forward styles such as IPAs and Pale Ales.

Key Brewing Uses:

  • Accentuates Hop Bitterness: Gypsum enhances perceived hop bitterness, making it perfect for hop-forward styles like West Coast IPAs.
  • Balances Water Profile: Adds calcium and sulfate to soft or RO water, helping to recreate classic regional brewing water profiles.
  • Improves Yeast Performance: Calcium promotes yeast flocculation and healthy fermentation.
  • Reduces Beer Haze: Calcium can help in protein coagulation during the boil, improving final clarity.

Application Tips:

  • Recommended Usage: Typical additions range from 0.5–1.0 grams per gallon depending on your desired sulfate level and target beer style.
  • Best For: American Pale Ales, IPAs, British Bitters, and any beer where enhanced hop crispness is desired.
  • When to Add: Add to strike water or mash to ensure proper mineral integration. Can also be added to the boil if needed for final adjustment.
  • Works Great With: RO water and distilled water brewers aiming for specific brewing water profiles.
