Cold Stabilization of Wine – Winemaker's Academy

Cold stabilization of wine is a method used to keep tartaric acid crystals from forming after the wine has been bottled This process is referred to as cold stabilization because it is the act of cooling the wine that causes tartaric acid to form tartrate crystals also known as wine crystals or wine diamonds

Acidity and pH

It is best to adjust the acid as early as possible because juice and wine are more stable at lower pH In the case of red musts it is advisable to adjust the pH to 3 4 or lower If the desirable TA cannot be achieved then the must should be adjusted to pH 3 4 regardless of the amount of tartaric acid required to do so

Acid Addition

Addition of tartaric malic and citric acids will affect the pH TA and taste of the wine differently *1 0 g/L addition of Tartaric acid will increase the TA by about 1 0 g/L and will decrease the pH by 0 1 pH units *1 0 g/L addition of Malic acid will increase the TA by about 1 12 g/L and will decrease the pH by 0 08 pH units

Using Tartaric Acid

I absolutely recommend that you bring your TA up and your pH down after MLF is complete This is best accomplished by tartaric acid because wine bacteria will not consume tartaric acid what you put in your wine will stay in your wine This will certainly help with aging and color stability because both of these things are compromised by wines that have too high of a pH

Titratable Acidity

Grapes contain significant amounts of organic acids The major organic acids in the must are tartaric malic and citric Of these three acids tartaric and malic acids account for over 90% of the total acid constituents of the juice (Amerine and Joslyn 1950) During ripening the tartrate and malate content of the fruit decrease This is accompanied by a steady increase in

Wine

Tartaric acid plays a key role in the stability of wines and influences the taste colour and odour of the final product A high tartaric content in a final bottled wine is indicative of the wine being unstable due to this it is important for winemakers to monitor the levels of tartaric acid present in wine

Monitoring Adjusting pH

The logic with regards to acidity and pH is that since some tartaric acid is made to crystallize and sediment acidity decreases along with a proportionate increase in pH (The extent of tartaric acid crystallization depends on wine chemistry mainly potassium content and temperature )
