Lactic Acid – Food Grade – 100mL

Lactic Acid is a high-quality, food-grade acidifier essential for precise pH control in brewing. Commonly used to lower mash or sparge pH, it helps prevent excessive tannin extraction and keeps your sparge runoff below the ideal 5.8 pH, resulting in a smoother, cleaner-tasting beer.

Lactic Acid is also perfect for pre-acidifying wort before adding souring bacteria such as Lactobacillus. This reduces the risk of unwanted wild bacterial growth by creating a more stable, low-pH environment.

Favoured by traditional brewers for being a natural byproduct of fermentation, lactic acid provides a gentle, authentic acidity — ideal for styles like Berliner Weisse, Gose, and other sour ales.

Key Features:

• 100mL bottle of food-grade Lactic Acid

• Lowers mash and sparge pH for improved flavour and clarity

• Prevents tannin extraction during sparging

• Used to pre-acidify wort for controlled souring

• Natural byproduct of fermentation – authentic and traditional

• Recommended for use with RAPT Recipe Builder or BrewFather for accurate dosage

Usage:
Add small, measured amounts to mash or sparge water to reach your target pH (typically 5.2–5.6). Use brewing software to determine precise additions for your setup.
