Supplied in a practical 230ml bottle at food-grade quality (E338), this concentrated phosphoric acid is one of the most effective and flavour-neutral pH correction tools available to the all-grain brewer — requiring significantly smaller additions than lactic acid to achieve the same pH shift, while contributing a clean, subtle flavour note that integrates seamlessly into the finished beer without the noticeable tartness that lactic acid can introduce at higher doses.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eWhat makes phosphoric acid a compelling alternative to lactic acid for mash and wort acidification is its combination of potency and flavour neutrality. At 75% concentration, H₃PO₄ is considerably stronger than standard lactic acid solutions — meaning the volume required to achieve a target pH correction is meaningfully smaller, reducing the risk of over-acidification and giving the brewer finer, more controllable dosing precision per addition. The phosphate anion released during acidification also acts as a yeast nutrient, providing an additional phosphorus source that supports healthy yeast growth and fermentation vigour — a secondary benefit that no other common brewing acid delivers. In the wider brewing industry, phosphoric acid is the standard acid of choice for yeast washing, where its antimicrobial properties at low pH help suppress bacterial contamination while preserving viable yeast cells for repitching.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eUsed correctly against a target water profile and measured mash pH, Brewferm Phosphoric Acid 75% gives homebrewers a fast-acting, precise, and flavour-safe pH correction tool that works equally well for strike water pre-acidification, in-mash pH adjustment, and post-boil wort acidification.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-pre-wrap leading-[1.7]\"\u003eLiquid acid — food grade E338 Phosphoric acid 75% concentration.
