In this article, we will delve into the science behind wine freezing, explore the effects of cold temperatures on different types of wine, and provide valuable tips on how to store your wine collection safely during the cold winter months.
Introduction to Wine Freezing
Wine is a complex beverage made from a mixture of water, ethanol, and other compounds. The freezing point of wine is lower than that of water due to the presence of ethanol, which acts as an antifreeze. However, this does not mean that wine is completely immune to freezing. The exact freezing point of wine depends on its alcohol content, with higher-alcohol wines being less susceptible to freezing.
Factors Affecting Wine Freezing
Several factors can influence the freezing point of wine, including:
The type of wine: Red wines tend to have a higher alcohol content than white wines, making them less prone to freezing.
The alcohol content: Wines with higher alcohol levels, such as fortified wines, have a lower freezing point than those with lower alcohol levels.
The storage conditions: Wines stored in colder temperatures, such as those found in unheated garages or basements, are more likely to freeze than those stored in warmer temperatures.
The wine’s sugar content: Wines with higher sugar levels, such as dessert wines, may be more resistant to freezing due to the presence of sugars, which lower the freezing point.
Understanding the Freezing Point of Wine
The freezing point of wine is typically lower than 32°F (0°C), which is the freezing point of water. However, the exact freezing point of wine can vary depending on the factors mentioned above. As a general rule, wines with an alcohol content of 12% or higher are unlikely to freeze at temperatures above 25°F (-4°C). On the other hand, wines with an alcohol content below 10% may start to freeze at temperatures around 30°F (-1°C).
Effects of Cold Temperatures on Wine
Cold temperatures can affect wine in various ways, even if it does not freeze. Some of the effects of cold temperatures on wine include:
Impact on Wine Quality
Cold temperatures can cause wine to become cloudy or develop off-flavors. This is because the cold temperature can cause the wine’s compounds to precipitate out of solution, resulting in a cloudy appearance. Additionally, cold temperatures can slow down the oxidation process, which can affect the wine’s flavor and aroma.
Effect on Wine Storage
Wine storage is critical to maintaining the quality and integrity of the wine. Cold temperatures can cause the wine’s cork to dry out, which can lead to oxidation and spoilage. It is essential to store wine in a cool, consistent temperature, typically between 45°F (7°C) and 65°F (18°C), to slow down the aging process and prevent damage.
Types of Wine and Their Freezing Points
Different types of wine have varying freezing points, depending on their alcohol content and other factors. Some of the most common types of wine and their freezing points include:
Red wines, such as Cabernet Sauvignon and Merlot, typically have a freezing point around 25°F (-4°C) due to their high alcohol content.
White wines, such as Chardonnay and Sauvignon Blanc, have a freezing point around 28°F (-2°C) due to their lower alcohol content.
Dessert wines, such as Port and Sherry, have a lower freezing point, typically around 20°F (-7°C), due to their high sugar content.
Sparkling wines, such as Champagne, have a higher freezing point, typically around 30°F (-1°C), due to their lower alcohol content and higher pressure.

What happens to wine when it freezes?
When wine freezes, the water content in the wine turns into ice, causing the wine to expand. This expansion can lead to the wine bottle cracking or even shattering, which can be a significant problem for wine collectors and drinkers. The freezing point of wine is around 15°F to 20°F (-9°C to -7°C), which is lower than that of water due to the presence of alcohol and other substances. However, it’s essential to note that not all wines freeze at the same temperature, as the freezing point can vary depending on the wine’s sugar content, acidity, and alcohol level.
The effects of freezing on wine can be detrimental to its quality and character. When wine freezes, the formation of ice crystals can cause the wine to become cloudy or develop off-flavors. Additionally, the expansion and contraction of the wine can push the cork out of the bottle, allowing air to enter and potentially causing the wine to spoil. If you suspect that your wine has frozen, it’s crucial to check the bottle for any signs of damage or leakage. If the wine has frozen, it’s best to let it thaw slowly and naturally, rather than trying to heat it up or agitate the bottle, which can cause further damage to the wine.
Can all types of wine freeze in cold weather?
Not all types of wine freeze in cold weather, as the freezing point of wine can vary significantly depending on its composition. Wines with higher sugar content, such as dessert wines and ports, tend to have a lower freezing point than dry wines. This means that they can withstand colder temperatures without freezing. On the other hand, wines with higher water content, such as rosé and sparkling wines, are more prone to freezing due to their lower alcohol levels.
The type of grape variety used to make the wine can also affect its freezing point. For example, wines made from grape varieties like Riesling and Gewürztraminer, which are known for their high acidity and sugar content, tend to have a lower freezing point than wines made from grape varieties like Chardonnay and Cabernet Sauvignon.
