Why is testing for Tartaric Acid important in winemaking? Tartaric Acid is a unique acid that is not commonly found in fruit however it is a primary acid component in grapes It is one key acid that is monitored during the fermentation process as it plays a vital role in the stability of the wine and its pH levels

Spotlight on: Tartaric Acid

In winemaking tartaric acid serves to lower the pH of fermenting "must" to a level where many of the undesirable "spoilage" bacteria can't live It also acts as a preservative after fermentation in the mouth As I mentioned earlier tartaric acid can be used as a buffering agent in cosmetics taking the place of ethylenediamine

The Skin Benefits of Lactic Malic Phytic Tartaric and

Tartaric Acid This AHA comes from fermented grapes and is added to glycolic or lactic acid formulas to strengthen their sloughing But its primary benefit is its ability to regulate a formula's pH level Acids are notorious for morphing pHs and if they swing too high or too low in a product the result is skin irritation Rouleau says

The pH level at which the two curves begin to diverge in the graph is set by the value of the upper pKa value of tartaric acid and a close examination of the red curve in the graph shows a second change in slope of that curve at a pH value of about 3 0 which is due to tartaric acid

acidity

Highly acidic chemicals are known to be reactive and can cause severe burns Some common examples of acidic substances are carbonic acid in soft drinks (H 2 CO 3) uric acid in urine acetic acid in vinegar tannic acid (in tea and wine) tartaric acid (in grapes) ascorbic acid (Vitamin C) in fruit and citric acid in oranges and lemons

Acid Management in the Vineyard

– Ratio of tartaric to malic depends on variety and temperature during ripening (0 6 to 3 4) – Breakdown of malic acid during ripening accounts for decreasing titratable acidity • High temps = low TA esp malic acid levels – Tartaric acid is converted to K+ salt forms (Extent of Exchange) which causes pH to increase

What is Tartaric Acid?

Tartaric acid starts in the grape The levels are consistent from flowering to ripening right through to harvest However the overall pH level of the grape will increase as it ripens The strength of tartaric acid is significantly reduced by dilution within the berries As the grape ripens juice and sugars mix with the acid

Tartaric Acid Chemical and Physical Properties

Tartaric acid is a white crystalline organic acid It occurs naturally in many plants particularly grapes and tamarinds 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 Salts of tartaric acid are known as tartrates It is a dihydroxy derivative of dicarboxylic acid

Monitoring Adjusting pH

To lower pH the most effective method (and as close as natural as it can be) is to add tartaric acid A 1 0 g/L addition causes a shift of approximately 0 1 in pH Citric acid is not recommended at least not in wines that will go through MLF as malolactic bacteria will metabolize the acid into acetic acid and increase volatile acidity (VA)
