Unlike red wine, during white wine production, winemakers intentionally initiate cold stabilization as a way to remove tartrates that can develop when the wine is chilled. When the cork pushes out, wine can leak out and air can leak in, enabling oxidation. The liquid expands, and the pressure either pushes the cork out or breaks the bottle. When water freezes, it expands as anyone who has left a bottle in the freezer knows. Wine not adequately protected during shipping can suffer significantly when external temperatures approach 5 ☏. Freezing can damage the wine, the cork, and the bottle. Due to its alcohol content, wine freezes at a lower temperature than water, around 20 - 22 ☏. You may not realize that extreme cold temperatures impact wine too. The taste will not be fresh but subdued with cooked flavor characteristics. Wine and air begin to seep through the cork, leading to oxidation of the wine. Nearing 86 ☏ and above, wine starts to cook, and the pressure will begin pushing the cork out. If the internal bottle temperature rises above 80 ☏, wine can begin to deteriorate. When subjected to extreme temperatures, your wine purchases may not arrive in the condition you expect.įor years, wine shipping in the heat of the summer has been discouraged. How Extreme Temperatures Impact Shipping Wine We need to approach shipping wine with a new mindset. But given the unpredictable weather we are experiencing as climate change accelerates, this idea no longer holds. Conventional wisdom said wine shipping occurred only in the spring or fall. As these weather events become more common, shipping wine becomes riskier.

Polar vortexes, 100-year floods, Cat 5 hurricanes, wild brushfires, high-intensity tornadoes, extended heat spikes.
