Organic acids

Organic chemical compounds that undergo an equilibrium reaction with water or other solvents. The term organic acids is often equated with carboxylic acids, but the latter are only one of the many groups. The groups also found in wine include alcohols, carboxylic acids, phenols and thiols. They are distinguished by different degrees of acidity; carboxylic acids have a significantly more acidic character than alcohols or phenols. All acids without carbon content are called inorganic acids (exception carbonic acid = also inorganic).
