Last Updated on March 15, 2024 by Lydia Martin

Hennessy is a good-tasting and classy cognac, and most people love to consume it neat. However, some drinkers want to sip it cold. They even wonder whether it is safe to store Hennessy in a freezer. But wait, does Hennessy freeze?

Our team thoroughly scoured every possible source to know the answer. Curious yet? Then read on. 

Hennessy Cognac: Does It Freeze?

Yes, Hennessy Cognac freezes because alcoholic beverages have freezing points [1]. There can be two main reasons why alcohol doesn’t freeze. One main reason is that high alcohol content prevents the liquor from freezing easily. Another reason is that home freezers cannot reach the temperature required in freezing alcohol, so the liquor cannot freeze.  

Wine and beer have low alcohol content, but vodka, whiskey, and cognac require massive temperature drops to freeze completely. Since a normal home freezer cannot reach such temperatures, they thought spirits like Hennessy do not freeze solid. 

Hennessy’s Freezing Point 

Like most hard liquors, Hennessy has a high ABV of 40%. Hennesy’s freezing point is at about -16 °F or -26.67 °C. Hennessy contains a substance called ethanol or ethyl alcohol with a low freezing limit required to make alcohol freeze. 

Should You Keep Hennessy in the Freezer? 

Hennessy VS Cognac

No, you should not keep Hennessy in the freezer. Most alcoholic beverages like cognacs and vodka should avoid extreme hot and cold temperatures. 

However, alcohol does not permanently affect when stored in freezers, especially in a typical refrigerator. Refrigerators are set at 0°F by the FDA, so they will not reach the glacial state of alcoholic drinks like vodka, cognacs, and whiskey and make alcohol freeze. 

Is It Safe to Store Cognac in the Freezer? 

Yes, it is safe to store Cognac in the freezer, especially since normal freezers cannot reach the glacial state of high ABV alcohol. Most alcohol is consumed frozen (wine and beer), so people put it in the freezers, and if you are planning to store Cognac in freezers, it is totally safe. 

When vodka hangs out in freezers, it has a better texture. However, you must consider the extreme coldness of Cognac. Extreme coldness can lessen the complexity and intensity of the flavors as our tongues are capable of discerning them [2]. 

What Happens When You Put Henny in the Freezer

Unlike low-proof liqueurs like beer and wine, when you put Hennessy in the normal freezer, it will get cold but not freeze. The main reason why it will not freeze is the high percent alcohol the spirit contains. 

If Hennessy is stored in a freezer but does not reach -16 °F, it will just get cold. If the temperature drops to -16 °F, the thickness of the liquid increases, but it won’t taste good for some. 

How Long Should It Stay in the Freezer? 

Unopened Hennessy bottle can stay in the freezer indefinitely, just like beer and wine, because it is entirely safe from external causes for degradation, especially if it is a home freezer. 

However, if the refrigerator you use can reach temperatures that can make alcohol freeze, the spirit should not be kept for too long. When liquid freezes, it produces pressure as it expands, and it can cause cracks on the bottle, or the cork will be pushed out. But, how much Hennessy will get you drunk?

Frequently Asked Questions (FAQs)

Does putting Hennessy in the freezer make it weaker?

No, putting Hennessy in the freezer will not make it weaker. There is no evidence that coldness brings a permanent effect on the liquid, such as lowering the percent alcohol. But it will surely affect your tongue and sense of taste. 

Can home freezers freeze Hennessy?

No, home freezers cannot freeze Hennessy, unlike beer. Based on the FDA, home freezers are set to 0°F, and since Hennessy’s glacial limit is at -16 °F, it will not happen. 

Can you drink Hennessy frozen?

Yes, you can drink Hennessy frozen, which has an almost velvety taste. However, we don’t recommend you to freeze Cognac and whiskey because your tongue may not be able to taste the intensity and flavor of the spirit.

Why doesn’t Hennessy freeze?

Hennessy and other high-proof spirits like it contain a significant amount of alcohol, which has a lower freezing point than water. The freezing point of pure ethanol, the type of alcohol found in alcoholic beverages, is around -173 degrees Fahrenheit (-114 degrees Celsius). Since most home freezers typically operate at temperatures above this freezing point, Hennessy and other alcoholic beverages with similar alcohol content will not freeze in a standard household freezer.

What alcohol won’t freeze?

Alcohol with a high proof or alcohol by volume (ABV) content won’t freeze in typical household freezers. The freezing point of pure ethanol, the primary alcohol in alcoholic beverages, is extremely low. As a result, high-proof spirits, such as Everclear, Bacardi 151, or overproof rums, won’t freeze at temperatures found in home freezers. This property is due to the lower freezing point of alcohol compared to water.

Should you freeze cognac?

While it won’t harm cognac to freeze it, it’s generally not recommended to store high-quality spirits, including cognac, in the freezer for an extended period. Freezing may cause some compounds in the spirit to precipitate or change the texture. Additionally, temperature extremes, such as repeated freezing and thawing, can affect the flavor and aroma of the cognac over time. It’s best to store cognac at room temperature and enjoy it at its optimal serving temperature, typically slightly warmer than refrigeration temperature.

Is it OK to put liquor in the freezer?

It is generally okay to put liquor in the freezer, especially if you prefer your spirits served very cold. Many people store vodka, gin, tequila, and other spirits in the freezer to chill them before serving. However, keep in mind that this may dull some of the flavors, as colder temperatures can momentarily suppress taste receptors. While storing most spirits in the freezer is safe, it’s not advisable for certain liqueurs or cream-based spirits, as freezing can alter their texture and flavor. Additionally, for higher-quality spirits, storing them in the freezer for an extended period may not be ideal, as it could affect their overall characteristics.

Can I put brandy in the freezer?

While it’s technically possible to put brandy in the freezer, it’s not always recommended for high-quality or aged brandies. Cold temperatures can dull the flavors of brandy, and the alcohol may become thicker, altering its texture. However, if you prefer your brandy very cold or plan to use it in cocktails, placing it in the freezer for a short period may be acceptable. Keep in mind that storing brandy in the freezer for an extended time might affect its overall characteristics.

Does Hennessy have to be cold?

Hennessy does not have to be cold, and it is often enjoyed at room temperature or slightly chilled. Serving Hennessy at room temperature allows the flavors and aromas to be more pronounced. Some people prefer to chill Hennessy slightly by serving it over ice or with a splash of water, but it does not need to be extremely cold. Ultimately, the ideal serving temperature for Hennessy is a matter of personal preference.

Can 100% alcohol freeze?

No, 100% pure alcohol, or absolute ethanol, cannot freeze under normal freezer temperatures. The freezing point of pure ethanol is approximately -173 degrees Fahrenheit (-114 degrees Celsius), which is much lower than the temperature of a typical household freezer. Therefore, 100% alcohol will remain in liquid form at standard freezer temperatures. It’s worth noting that commercially available alcoholic beverages are not 100% alcohol but rather a mixture of alcohol and water, so they can freeze under certain conditions.

What liquor goes in the freezer?

Many people choose to chill certain types of liquor in the freezer before serving. Vodka, gin, tequila, and other clear spirits are commonly stored in the freezer as they can be enjoyed cold, and the chilling can help reduce the bite of the alcohol. However, it’s not recommended to store higher-quality or aged spirits in the freezer for an extended period, as this may affect their flavor and texture. Additionally, liqueurs or cream-based spirits may not freeze well and could undergo changes in texture and flavor. Ultimately, the decision to store liquor in the freezer depends on personal preference and the type of spirit being used.

Can alcohol expire?

Alcohol, particularly high-proof spirits, does not have a definite expiration date. The high alcohol content acts as a preservative, preventing the growth of bacteria or spoilage. However, the flavor and quality of some alcoholic beverages, especially those with lower alcohol content or added ingredients, can change over time. For example, wine, beer, and some liqueurs may degrade in flavor if stored improperly or for an extended period. Checking for any unusual odors, flavors, or changes in appearance can help determine if a specific alcoholic beverage has undergone spoilage or deterioration.

What causes alcohol not to freeze?

Alcohol, with its lower freezing point compared to water, prevents alcoholic beverages from freezing under normal household freezer temperatures. The freezing point of pure ethanol, the primary alcohol in alcoholic drinks, is approximately -173 degrees Fahrenheit (-114 degrees Celsius). Since most household freezers operate at temperatures significantly above this point, alcoholic beverages, even those with lower alcohol content, remain in liquid form. The presence of water in alcoholic beverages contributes to a higher freezing point than pure alcohol but still below typical freezer temperatures.

Is Hennessy good over ice?

Enjoying Hennessy over ice is a matter of personal preference. Serving Hennessy over ice can be a delightful way to slightly chill the drink, enhancing its flavors and aromas. The cold temperature can mellow the intensity of the alcohol, allowing the subtleties of the cognac to shine through. Some people prefer sipping Hennessy neat, while others appreciate the experience of the drink evolving as the ice melts. Ultimately, whether Hennessy is good over ice depends on individual taste preferences.

Why does whiskey not freeze?

Whiskey does not freeze easily due to its alcohol content. The freezing point of ethanol, the primary alcohol in whiskey, is significantly lower than the temperatures found in most household freezers. The alcohol acts as a natural antifreeze, preventing the liquid from solidifying at typical freezing temperatures. Additionally, whiskey often has a relatively high alcohol by volume (ABV), typically around 40-50%, further inhibiting freezing. While whiskey may thicken or become more viscous when exposed to very low temperatures, it remains in liquid form in a standard household freezer.

So, Does Hennessy Freeze?

Hennessy can freeze because cognac has certain glacial and melting points. Alcohol freezes when it reaches a certain temperature, and since Hennessy has a glacial point of -16 °F, it will freeze once the freezer reaches the same temperature.

However, typical home freezers can only reach 0°F, so if you store Hennessy in your home refrigerator, it is safe, but it will not freeze.
