Acid Addition Details

Tartaric is the most common acid added to musts and wines and the addition should be made after a bench trial is done to confirm the desired acid level Tartaric acid contributes to cold instability so care should be taken when adding Tartaric acid to white wines close to bottling

Tartaric Acid

Tartaric acid is a white crystalline diprotic organic acid The compound occurs naturally in many plants particularly in grapes bananas and tamarinds It is also one of the main acids found in wine Tartaric acid can be added to food when a sour taste is desired It is also used as an antioxidant Salts of tartaric acid are known as tartarates

Acid Blends in Wine Making – Winemaker's Academy

Jun 25 2018Tartaric acid also brings tartness to wine and is the dominant acid in cranberries An acid blend is used to increase the titratable acidity of a wine While the point here is to adjust the amount of acids contained within the must it will have an effect on the pH of the must a measure of the strength of the acids present

DETERMINATION OF TITRATABLE ACIDITY IN WHITE WINE

In the United States the end point chosen is pH = 8 20 and the acid for reference is tartaric acid In some other countries for example France the end point is pH = 7 00 and the reference acid is sulphuric Titration acidity is commonly with in the range 4 0-8 0 g/dm3 expressed in tartaric acid

Tartaric Acid

Tartaric acid (2 3-dihydroxybutanedioic acid) is a naturally occurring dicarboxylic acid containing two stereocenters It exists as a pair of enantiomers and an achiral meso compound The dextrorotatory enantiomer of ( R R )- L - (+)-tartaric acid is widely distributed in nature

Wine acids not just tartaric

Lactic acid is more difficult to quantify in most winery laboratories however using the initial and final amount of malic acid before and after secondary fermentation allows a reasonable estimate to be made The contribution of succinic acid to titratable acidity was found to vary between 19% and 23%

Malic acid is abundant in green apples and unlike tartaric acid is widely found in nature Before veraison it can hit levels of 20 grams a litre in grapes In warm climates it is found in musts in the range of 1–2 grams per litre and in cooler climates it occurs at 2–6 grams per litre

Deacidification Improved Winemaking

At this high pH level enough tartaric and malic ions are in solution to form the double salt calcium tartrate malate After the treatment this portion of the must/wine is blended back into the bulk must/wine volume resulting in a suitable TA and pH having reduced both tartaric and malic acid levels

Titratable Acidity

The acid content of the must is determined by titrating a sample (a given volume) with a base such as sodium hydroxide solution to a phenolphthalein end point or alternatively to a pH of 8 2 The titratable acidity is expressed as grams of tartaric acid per 100 ml
