Acid adjustment calculator

Tartaric acid to raise titratable acidity, or potassium bicarbonate to lower it. Always bench-trial first: pH movement depends on buffering you cannot predict.

Tartaric acid to add

30.0 g

Direction

Acidifying

Bench-trial before treating the whole volume. How far pH moves for a given acid addition depends on the wine’s buffering capacity, which you cannot predict from TA alone.

Relation used

Tartaric at 1 g/L per 1 g/L TA; potassium bicarbonate at 0.9. If another calculator gives you a different answer, this is usually why. Neither is wrong; they are different published relations describing the same chemistry, and the useful thing is knowing which one produced the number in front of you.
