Cellars Choice Acid Blend – Malic Acid, Citric Acid, Tartaric Acid
Acid blends are mixtures of acids that are naturally found in wine making grapes. Most blends primarily contain malic, citric, and tartaric acids these are the tree most abundant acids found in grapes.
Malic acid contributes tartness to wines. It is the primary acid found in granny smith apples for a point of reference. Citric acid, the dominant acid found in citrus fruits. Tartaric acid brings tartness to wine and is the dominant acid in cranberries.
Acid blend is used to increase the titratable acidity of a wine. While the point here is to adjust the amount of acids contained within the must it will have an effect on the pH of the must, a measure of the strength of the acids present.
Grape acids are usually at the following concentrations:
- Tartaric = +6 g/L (50%)
- Malic Acid = 4-6.5 g/L (40%)
- Citric Acid = 0.1-0.7 g/L (10%)
Cellars Choice acid blend is composed of the following:
- Malic Acid = 50%
- Citric Acid = 40%
