Control mash pH and create clean, balanced sourness with Lactic Acid (88%), a concentrated liquid acidifier used by homebrewers to fine-tune brewing water and achieve precise acidi ty adjustments. This 4 oz bottle provides accurate dosing whether you’re lowering mash pH for better enzyme performance or adding controlled tartness to sour beer styles. Its neutral, dairy-like acidity makes it ideal for developing the bright, clean sour profile found in Berliner Weisse, Gose, and quick-soured ales. Lactic Acid is commonly used to bring mash pH into the optimal enzymatic range, improving extraction, clarity, and fermentation consistency. When used post-mash or during the boil, it can contribute gentle, rounded sourness without introducing harsh, citrus-like flavors. Its liquid form allows predictable adjustments in both small and large batches. This 88% concentration provides strong acidification power in a compact bottle, making it a reliable tool for brewers performing mash chemistry corrections, kettle souring, or recipe development that requires fine acidity control. It can be added directly to brewing water, wort, or finished beer in measured amounts based on taste or target pH. Widely used by home and commercial brewers for its consistency and ease of use, lactic acid offers a practical way to manage pH and shape the flavor profile of modern and traditional sour styles.
