Acid Reducing Solutions for Wine Making

Both potassium bicarbonate and calcium carbonate solutions can be used to reduce acid levels in finished wine. The preferred of these two is the potassium solution because the calcium carbonate solution results in an unpleasant taste to the wine.

When adding either of these solutions to wine, the wine maker should realize that the first acid that the solution will lower is the preferred acid, tartaric. The wine maker must take care that the tartaric acid present is not eliminated completely from the wine.

Reduction in acid levels in finished wine are accomplished at about a 1:2 ratio. Total acidity is reduced by 1g/L for every 2g/L of bicarbonate that is added to the wine. Dissolve the bicarbonate in a small quantity of wine and then add the solution to your wine. If your initial acidity reading indicates that you need to reduce the total acidity by 2g/L, do not make a solution totaling 4g/L (remember the 1:2 ratio) and add it to your wine all in one swoop. Instead, make small incremental additions of the solution and taste and take additional acidity measurements in between each further addition of solution.
