BREWERS’ GYPSUM is hydrated calcium sulfate used to correct mineral deficiencies in water which
is to be used for brewing. It is used in de-mineralized or soft to medium hard water to increase
permanent hardness. Used as directed, BREWERS’ GYPSUM is effective in eliminating the variations
in composition often encountered in water from surface sources. It will help establish proper pH of the
mash and the wort and provide sufficient calcium ions essential for enzyme function, kettle protein
coagulation and yeast metabolism.

Typical Properties
Form Crystalline powder
Color White
Solubility 0.26g per 100ml at 70ºF
Calcium, as Ca Min. 23%
pH of 10% slurry 7.3
Bulk Density - pcf 42.0 loose 70.0 compacted
Specific Gravity 2.32
Avg. particle size 12-15 microns

Suggested Procedures For Use
If possible, make up a 1% solution of BREWERS’ GYPSUM in cold water in a separate tank with
vigorous mixing. Calcium salts are more soluble in cold water, and the mixing will help dissolve the salt
more completely.

Dilute the BREWERS’ GYPSUM solution into water being heated for mashing or for sparging. The
final concentration of salts should be in the range of 100 to 1000 ppm (mg/L). This will require 2.5 to
25 lb/100 Bbl (10 to 100 g/Hl). If a tank is not available for making a solution ahead of time, the
BREWERS’ GYPSUM can be added directly to mash water or sparge water with as much mixing as
possible to assure dispersion.

Approval For Use In Brewing
The ingredient in BREWERS’ GYPSUM is approved for use in brewing and calcium sulfate is listed in
the Adjunct Reference Manual of the United States Beer Institute.

Packaging & Storage
Store in closed containers under dry conditions.  The product should be stored in
a cool, dry place.
