When it comes to enjoying a delicious glass of bourbon eggnog, many people wonder how long this festive drink can be safely kept. The shelf life of bourbon eggnog depends on various factors, such as whether it is store-bought or homemade, whether it contains alcohol, and how it is stored. Let’s delve into these details to understand how long you can enjoy your bourbon eggnog.
Shelf Life of Store-Bought Bourbon Eggnog
If you have purchased store-bought bourbon eggnog, the shelf life will be clearly indicated on the packaging. Unopened, shelf-stable bottled eggnog that contains alcohol typically has a longer shelf life, lasting up to 18 months without the need for refrigeration. This is due to the preservatives added to prolong its freshness.
Storage of Unopened Bourbon Eggnog
For unopened bottles of bourbon eggnog, it is best to store them in a cool and dark place, away from direct sunlight and heat. This ensures that the quality and taste remain intact for the longest period. However, always check the expiry date before consuming, even if the product is unopened.
Shelf Life of Opened Bourbon Eggnog
Once you open a bottle of bourbon eggnog, the shelf life changes. It is recommended to consume it within a few weeks after opening for the best taste and quality. However, factors such as the specific brand, storage conditions, and any additional ingredients added can influence its longevity.
Storage of Opened Bourbon Eggnog
To maximize the shelf life of opened bourbon eggnog, it is crucial to store it properly. Keep it refrigerated at all times when not serving. Make sure the container is tightly sealed to prevent moisture and other contaminants from affecting the drink. A cool temperature of around 35°F to 40°F (1.6°C to 4.4°C) will help maintain its freshness and flavor.
Homemade Bourbon Eggnog
If you prefer to make your own bourbon eggnog, the shelf life will be shorter compared to store-bought versions due to the absence of preservatives. As a general guideline, homemade eggnog typically lasts around three days when properly refrigerated.
Storage of Homemade Bourbon Eggnog
When storing homemade bourbon eggnog, it is essential to use clean and sanitized containers. Glass jars or airtight containers work best. Place the containers in the refrigerator as soon as possible after preparation to maintain its freshness. Remember that the alcohol content in bourbon eggnog can potentially extend its shelf life compared to traditional homemade eggnog.
Adding Alcohol to Extend Shelf Life
If you decide to add alcohol, such as bourbon, to your homemade eggnog, it may have a longer shelf life. Alcohol acts as a preservative, inhibiting the growth of harmful bacteria. Eggnog with an alcohol content of at least 5 percent may last for a few weeks when refrigerated.
Signs of Spoilage
As with any perishable food or drink, it is crucial to pay attention to signs of spoilage in bourbon eggnog. If you notice any unusual odor, mold, or a sour taste, it is best to discard the eggnog immediately. Consuming spoiled eggnog can lead to foodborne illnesses, which can ruin the holiday spirit.

In Conclusion
The shelf life of bourbon eggnog varies depending on whether it is store-bought or homemade, contains alcohol, and how it is stored. Store-bought bourbon eggnog can last up to 18 months when unopened, while homemade eggnog typically lasts around three days. Once opened, it is essential to refrigerate the eggnog and consume it within a few weeks for optimal taste and quality. Remember to always check for signs of spoilage and discard any eggnog that appears or smells off. Enjoy your bourbon eggnog responsibly and have a festive holiday season!
