Magnesium Sulphate (Epsom salts) is a key brewing water salt, added in small amounts to adjust the mineral profile of your mash and sparge water. It supplies magnesium - an important yeast nutrient - and sulphate, which sharpens and accentuates hop bitterness for crisper, drier beers.
- Adds magnesium & sulphate to your brewing liquor
- Enhances hop character - ideal for pale ales and IPAs
- Supports yeast health in soft, low-mineral or RO water
Typical dosage: roughly 1g per 10-20 litres, adjusted to hit your target water profile. Always calculate additions against your source water, as too much can taste harsh or bitter.
