Calculators

Acid adjustment calculator

Work out how much tartaric acid raises a wine's TA to your target, or how much potassium bicarbonate or calcium carbonate lowers it.

Bench arithmetic, with the working shown. Nothing here is saved, and none of these numbers is a figure for a label. Each one comes from a working formula with its assumption stated. Bench-trial anything before it goes into a tank.

Tartaric acid1.57 kg

1.30 g/L. Expect pH to fall roughly 0.13. Dissolve it in a little wine, add it in two passes, and taste in between.

Per gallon4.92 g/gal

Bench-trial this rate on a 1 L sample before you treat the whole tank.
