INTRODUCTION:

Tartaric acid occurs naturally in grapes and is one of the most

prevalent organic acids, along with L-malic acid, present in wines.

Throughout the wine making industry it is assumed that tartaric

acid is the only acid that contributes to total (titratable) acidity in

wine and as such the measurement of tartaric acid is used as the key

indicator of total acidity. The general levels of total acidity in wines

range from approximately 0.4 to 1.0% (w/v). During the wine making

process, if the total acidity of a wine is too low, tartaric acid can be

added to the wine to increase the level of acidity and consequently

decrease the pH level. This in turn acts as a preservative against

microbial spoilage.

This kit (K-TART) is suitable for the specific measurement of tartaric

acid, especially in wines and fruit juices.
