Lowers pH by a small amount.

Can be used to add sulfate "crispness" to the hop bitterness. Often used at half the levels of Gypsum. 1 gram in 1 gallon changes the salt levels by 103 ppm sulfate, 26 ppm Magnesium and adds 108 ppm to the hardness.

Epsom salt is also ideal as a nutrient source for growing hop plants.

Feeling sore after brewing happy all day and night and your hands or feet are aching, try adding 55g of epsom salt to 5 Litres of hot water and soak for ten minutes. Temporarily relieves pain.

Magnesium Sulphate aka Epsom Salt MgSO4 * 7H20 is an important mineral for its effect on mash and wort pH. It is used as a brewing salt in brewing to adjust the ion content of the wort and enhance enzyme action in the mash to promote a desired flavour profile in the beer. Sulphate enhances hop bittering, but must be balanced with chlorides. Magnesium has a low ppm threshold for being safe (brewing range 0-30 ppm), so use this one sparingly.

Target ranges for mineral levels in beer brewing:

Flavor Ions:

Calcium (Ca⁺²) – target range of 50-150 ppm
Magnesium (Mg⁺²) – target range of 0-30 ppm
Sulfate (SO₄^-2)- target range 50-150 ppm for normal beers, 150-350ppm for highly bitter beers.
Sodium (Na⁺) – target range 0-150 ppm
Chloride (Cl^–) – target range 0-250 ppm.

Harmful levels:

Concentrations above these levels are harmful to the beer, and much beyond they become harmful to our health!

Calcium (Ca⁺²) – 250 ppm
Magnesium (Mg⁺²) – 50 ppm
Sulfate (SO₄^-2) – above 750 ppm
Sodium (Na⁺) – above 200 ppm
Chloride (Cl^–) – above 300 ppm

Sulphate and Chloride should be balanced in beer:

2:1 SO4 to Cl is good for bitter beer
1:2 SO4 to Cl for mild ales
1:3 SO4 to Cl for stouts and porters
Chloride and Sodium add the maltiness of a beer.
Sulfate highlights bitterness and reduces malt flavor.

Alkalinity Range:

Alkalinity impacts the pH of the mash, a key factor in efficiency. Bicarbonate (HCO₃^–) – ppm depends on style of beer, lower for lighter beers, higher for darker beers.

0-50 for pale beers
50-150 for amber beers
150-400 for dark beers
