What is cold stabilization?

• A. Movement of wine between vessels
• B. Pigeage
• C. Elevage
• D. A process that causes tartrate crystals to precipitate out of the wine at approximately 25°F

Answer: (D)

Cold stabilization is a pre-bottling treatment that chills the wine to near-freezing temperatures so potassium bitartrate tartrate crystals can form and precipitate out. By cooling to about 25°F (-4°C), tartrates crystallize and are removed, preventing crystals from forming in the bottle later. This helps keep the wine clear and avoids the chalky “wine diamonds” that some people notice after purchase. The other terms refer to different stages or actions in winemaking: moving wine between vessels is just transferring, pigeage is the gentle breaking of the cap during fermentation, and elevage is the aging and maturation process.
