Mentioned in:
Adds sulfate and magnesium ions to brewing water. Adjusts mash pH down (very slightly).
Make sure to buy pure epsom salt and not special types sold for bath use that have scents and/or dyes added. The only ingredient should be magnesium sulfate (MgSO4). In the USA, any package that has a “drug facts” box or that is labeled "USP" has been manufactured, tested and certified to meet the regulatory standards of the FDA and the United States Pharmacopeia, and is deemed safe and acceptable for human use.
Different beer styles will call for different salt additions. For more information see our Water Adjustment guide.
