Dialing in Sparge Water pH and Temperature

A lot of brewers focus on mash pH, but sparge water can make or break your final wort. If the sparge water is too hot or the pH creeps too high, you risk extracting tannins and silicates from the grain husks. The result? Astringency, bitterness, and that “drying” flavor nobody wants in their beer. Keeping sparge water at the right temperature—around 168–170°F—and holding the pH below 6.0 ensures you’re rinsing sugars, not harsh compounds.

The right sparge adjustment is also about consistency. Acidifying sparge water when needed with lactic acid or phosphoric acid protects the flavor while still maximizing efficiency. It’s a small detail, but one that separates clean, well-balanced beer from one that feels rough around the edges. Pay attention to sparge water, and you’ll get more predictable mash efficiency, smoother wort, and beer that finishes as crisp and clean as you intended.
