Magnesium Sulphate (Epsom) - 100g

Magnesium Sulfate (Epsom Salt) – Food Grade – 100g

Top Brew's Magnesium Sulfate, also known as Epsom Salt, is a versatile brewing salt used to enhance hop crispness and slightly lower mash pH. Commonly used in pale ales and hop-forward beers, it adds a subtle sulfate sharpness that accentuates hop bitterness and helps create a clean, dry finish.

While similar to calcium sulfate (gypsum), magnesium sulfate is less effective at reducing pH but provides valuable magnesium (Mg) for yeast health when used in small amounts.

Key Features:

• 100g pack of food-grade Magnesium Sulfate (Epsom Salt)

• Slightly lowers mash pH and enhances hop crispness

• Adds essential magnesium for healthy yeast fermentation

• Ideal for pale ales, IPAs, and hop-forward beer styles

• Use sparingly – excessive amounts may have a laxative effect

Brewing Guidance:
Maintain magnesium levels between 10–30 mg/L to promote yeast activity and balance flavour. Excess magnesium can create a dry or astringent taste.
Sulfate levels influence hop character — 30–70 mg/L for most ales and up to 130 mg/L for highly hopped beers.

Usage:
Dissolve the desired amount in brewing water according to your target water profile. Always measure carefully and use a brewing water calculator for precision.
