HI84102 mini Titrator - Unitech Scientific

1 HI84102miniTitratorFOR THE DETERMINATION OF TITRATABLETOTAL acidity FOR WINE ANALYSISA cids occur naturally during the growing ofgrapes and as a part of the fermentationprocess. Wines show lower levels of acidwhen there are hot growing seasons or whenthe grapes come from hotter regions. In theproper proportion, acids are a desirable traitand give the wine three predominant acids in wine are tar-taric, malic and citric-all of which are intristicto the acid is the principal acidin grapes and is a component that promotesa crisp flavor and graceful aging in wine. Amoderate amount of a wine s acid comesfrom malic acid (which contributes to fruiti-ness) and a small amount of acid comesfrom citric acid. Wine also contains traceamounts of other acids. The least desirableacidin wine is acetic acid, which, when present inmore than a nominal amount, gives wine asour or vinegary acidity (also called titratable acidity ) isthe sum of the fixed and volatile acids.

2 In theUnited States, the total acidity is usuallyexpressed in terms of tartaric acid, eventhough other acids are acidity directly effects the color and flavorof wine and, depending on the style of wine,is sought in a perfect balance of sweet and bittersensations of other components. Too muchacidity makes wine tart and sharp; too littlemakes wines flat, flabby and acidity in wine is what makes it refresh-ing and an ideal accompaniment to proper acid level of a wine varies, withsweeter wines generally requiring somewhathigher levels to retain the proper balance.
