Acids in Wine



The acid content in wine provides an exhilirating organoleptic experience to wine drinkers. The characteristic tartness, crispness, and bitter taste is what makes the wine very appealing and makes you go back for more. Cool regions produce grapes with higher acidity while warm regions produce grapes that are lower in acid content.

Tartaric acid and malic acid account for 70 to 90% of all organic acids found in grape berries and leaves.
  • Tartaric acid is one of the major types of acid that helps make the chemical content of the wine stable under changing conditions and has a significant influence on the finished wine's color, taste and distinct flavor. This acid is present in tamarind, bananas and grapes. It imparts the sour taste to wine in combination with other types of acids. The level of acidity of tartaric acid does not vary a lot as the berries mature.
  • Malic acid is another important acid that imparts sour taste to wine. It is present in all types of berries and fruits but is historically associated with green apples. The level of acidity of malic acid varies a lot as the berries mature and ripen.
