Lactic Acid 100ml and 1 litre bottles
Lactic Acid is used in many Belgian beer styles to sour the beer.
88% Lactic Acid
Acid additions counter the H+ ion and directly lower the alkalinity of the mash.
Popular additions include phosphoric acid and lactic acid. All of these contribute other flavors and ions to the beer as well, which can again cause problems if used in excessive amounts. Lactic acid will add lactates. Sulfuric acid will contribute sulfates. In general you should add the minimum needed to achieve your target pH or the level of sourness desired. The amount will vary depending on the concentration of your acid and wort volume.
