Tartaric acid
is a white crystalline
diprotic
aldaric acid
. It occurs naturally in many plants, particularly
grapes
,
bananas
, and
tamarinds
, is commonly combined with baking soda to function as a leavening agent in recipes, and is one of the main acids found in
wine
. It is added to other foods to give a sour taste, and is used as an
antioxidant
.
Tartaric acid may be most immediately recognizable to wine drinkers as the source of "wine diamonds", the small
potassium bitartrate
crystals that sometimes form spontaneously on the
cork
. These "tartrates" are harmless, despite sometimes being mistaken for broken glass, and are prevented in many wines through
cold stabilization
. The tartrates remaining on the inside of
aging barrels
were at one time a major industrial source of potassium bitartrate.
However, tartaric acid plays an important role chemically, lowering the pH of fermenting "must" to a level where many undesirable spoilage bacteria cannot live, and acting as a preservative after
fermentation
. In the mouth, tartaric acid provides some of the tartness in the wine, although
citric
and
malic acids
also play a role.
