It lowers mash and wort pH by a small amount, adds sulphate crispness to accentuate hop bitterness, and provides magnesium — an essential mineral for yeast health and certain fermentation reactions.\u003c\/p\u003e\n\u003ch3\u003eBeer Making\u003c\/h3\u003e\n\u003cp\u003eAdds sulphate crispness and increases hop bitterness perception, similar in effect to \u003ca href=\"\/products\/gypsum-100g\"\u003eGypsum (Calcium Sulphate)\u003c\/a\u003e but contributing magnesium rather than calcium. Adding 1 teaspoon to 23 litres of brewing water increases magnesium ion levels by approximately 50 ppm and sulphate levels by approximately 210 ppm.\u003c\/p\u003e\n\u003ch3\u003eBurtonisation\u003c\/h3\u003e\n\u003cp\u003eBurton-on-Trent was historically renowned for its pale ales, owing to the high mineral content of the local water.
