Magnesium Sulphate (Heptahydrate) is a salt used to increase the mineral content of brewing liquor to improve its brewing quality and produce the desired beer characteristics.


  • Increases Sulphate content of brewing liquor without increasing Calcium content.
  • Imparts dry bitter character to beer.
  • Magnesium ions help reduce wort pH (to a lesser extent to Calcium Ions).

Application and rates of use

Magnesium Sulphate is normally added to the grist prior to mashing.

Magnesium Sulphate should NOT be added to the hot liquor tank (HLT), as some constituents are insoluble. They will remain in the hot liquor tank as opposed to being released into the grist, thus requiring the HLT to be cleaned on a regular basis.

Rates of Magnesium Sulphate should be determined based on the final brew-length and are dependant on the levels of calcium, magnesium, sulphate and chloride present in your untreated liquor. Magnesium levels must not exceed 50ppm.

Levels of the relevant ions present in your liquor can be obtained from your Local Water Authority
