Total acids determination in wine with different methods

During the maturation process acids represent an essential factor in wine quality. The amounts of total acids, in 38 different wines, were determined by titrimetric as well as potentiometric methods. Potentiometric titration method gives higher values for total acids content (4.99–10.79 g/l) compared to titrimetric method (3.85–8.68 g/l) as it includes all multi basic acids determination which gives more realistic information about wine acidity.
