Eggnog, that creamy, decadent holiday beverage, is a staple in many households during the festive season. Whether you’re sipping it straight, spiking it with your favorite spirit, or using it in baking, knowing how long eggnog lasts in the refrigerator is crucial to avoid foodborne illness and wasted cheer. This comprehensive guide delves into the factors affecting eggnog’s shelf life, how to properly store it, signs of spoilage, and more, ensuring you can enjoy this festive treat safely.
Understanding Eggnog Shelf Life: A Matter of Time and Ingredients
The shelf life of eggnog isn’t fixed; it varies depending on whether it’s store-bought or homemade, pasteurized or unpasteurized, and how carefully it’s stored. Understanding these factors is the first step in keeping your eggnog fresh for as long as possible.
Store-Bought vs. Homemade Eggnog
Store-bought eggnog, typically pasteurized and often containing preservatives, generally lasts longer than its homemade counterpart. Pasteurization is a heat treatment process that kills harmful bacteria and extends the shelf life of the product. Homemade eggnog, while often richer and more flavorful, lacks this protective barrier and thus has a shorter lifespan.
Pasteurized vs. Unpasteurized Eggnog
Pasteurization plays a significant role in extending the shelf life of eggnog. Pasteurized eggnog has been heated to a specific temperature to kill bacteria, making it safer and longer-lasting. Unpasteurized eggnog, on the other hand, contains raw eggs, which can harbor harmful bacteria like Salmonella. This type of eggnog should be consumed within a very short timeframe.
How Long Does Eggnog Last in the Refrigerator? The Breakdown
Knowing the specific timeframes for different types of eggnog is essential for safe consumption. Here’s a detailed breakdown:
Store-Bought Eggnog (Pasteurized)
An unopened carton of store-bought, pasteurized eggnog can typically last 5-7 days past the “sell-by” or “use-by” date printed on the carton, provided it’s been stored properly in the refrigerator. Once opened, it’s best to consume it within 2-3 days. Always check for any signs of spoilage before drinking, even if it’s within the recommended timeframe.
Homemade Eggnog (Pasteurized)
If you’ve pasteurized your homemade eggnog, it will last longer than unpasteurized versions but still not as long as commercially produced options. You can expect pasteurized homemade eggnog to stay fresh for 2-4 days in the refrigerator.
Homemade Eggnog (Unpasteurized)
Unpasteurized homemade eggnog is the most perishable. It should be consumed within 1-2 days of preparation. Due to the risk of Salmonella, exercising extreme caution with unpasteurized eggnog is vital, especially for vulnerable populations like pregnant women, young children, and the elderly.
Eggnog with Alcohol
Adding alcohol to eggnog can slightly extend its shelf life due to alcohol’s preservative properties. However, don’t rely on alcohol to completely eliminate the risk of spoilage. While the alcohol content can inhibit bacterial growth to some extent, it doesn’t kill existing bacteria. You can generally add an extra day or two to the timelines mentioned above, but always prioritize food safety.
Proper Storage: Maximizing Eggnog Freshness
How you store your eggnog significantly impacts its longevity. Following these guidelines will help you keep your eggnog fresher for longer.
Refrigeration is Key
Eggnog must be refrigerated at 40°F (4°C) or below at all times. This temperature range inhibits the growth of harmful bacteria. Make sure your refrigerator is functioning correctly and that the eggnog is stored on a shelf where the temperature is consistently cold.
Original Container is Best
If possible, store eggnog in its original container. The container is designed to protect the eggnog from external contaminants and temperature fluctuations. If you’ve made homemade eggnog, store it in an airtight container.
Avoid Temperature Fluctuations
Minimize temperature fluctuations. Don’t leave eggnog at room temperature for extended periods. When serving, only pour out what you need and promptly return the remaining eggnog to the refrigerator.
Recognizing Spoilage: Signs Your Eggnog Has Gone Bad
Even if your eggnog is within the recommended timeframe, it’s crucial to check for signs of spoilage before consuming it.
Visual Inspection
Look for any changes in color or texture. Spoiled eggnog may appear thicker than usual or have a lumpy consistency. The color might also change, becoming darker or developing an off-white hue.
Smell Test
The smell is a reliable indicator of spoilage. Fresh eggnog has a sweet, creamy aroma. If it smells sour, acidic, or off in any way, it has likely gone bad.
Taste Test (With Caution)
If the visual and olfactory tests are inconclusive, take a very small sip. If the eggnog tastes sour, bitter, or otherwise unpleasant, discard it immediately. Do not consume more than a tiny amount if you suspect spoilage.
Trust Your Instincts
If you’re unsure about the freshness of your eggnog, it’s always best to err on the side of caution and throw it away. Food poisoning is not worth the risk.
Tips for Extending Eggnog’s Shelf Life
While you can’t indefinitely prolong the life of eggnog, these tips can help you maximize its freshness:
Buy Fresh
When purchasing store-bought eggnog, check the “sell-by” or “use-by” date and choose the carton with the latest date. This ensures you’re starting with the freshest product possible.
Proper Handling
Avoid cross-contamination. Use clean utensils when handling eggnog, and don’t return any eggnog that has been exposed to air or other food items back to the original container.
Consider Freezing (With Limitations)
Freezing eggnog can extend its shelf life, but it can also affect its texture. Eggnog tends to separate when frozen and thawed, resulting in a grainy or watery consistency. If you choose to freeze eggnog, do so in an airtight container and leave some headspace to allow for expansion. Thaw it in the refrigerator and whisk vigorously to recombine the ingredients. Be aware that the texture may not be the same as fresh eggnog.
Small Batches
If you’re making homemade eggnog, consider making smaller batches so you can consume it within the recommended timeframe without having to worry about spoilage.
Eggnog Safety Considerations
Consuming spoiled eggnog can lead to foodborne illness, so it’s important to be aware of the potential risks.
Salmonella Risk
Unpasteurized eggnog poses a risk of Salmonella contamination. Salmonella is a bacteria that can cause fever, diarrhea, abdominal cramps, and vomiting. Symptoms typically appear within 12 to 72 hours after infection.
Other Bacteria
Besides Salmonella, other bacteria, such as E. coli and Listeria, can also contaminate eggnog if it’s not stored or handled properly.
Vulnerable Populations
Certain populations are more susceptible to foodborne illnesses, including pregnant women, young children, the elderly, and individuals with weakened immune systems. These groups should avoid consuming unpasteurized eggnog and exercise extra caution when consuming any type of eggnog.
Creative Ways to Use Eggnog Before It Spoils
If you have leftover eggnog and you’re concerned about it going bad, consider using it in recipes:
Eggnog Pancakes or Waffles
Add eggnog to your pancake or waffle batter for a festive twist. The eggnog will add richness and flavor to your breakfast.
Eggnog French Toast
Soak your bread in an eggnog mixture before frying it for a decadent French toast.
Eggnog Latte
Heat up eggnog and add it to your coffee for a creamy and flavorful latte.
Eggnog Bread Pudding
Use eggnog as the base for your bread pudding for a rich and custardy dessert.
Eggnog Ice Cream
Use eggnog as the base for your ice cream for a festive and flavorful treat.

How long does homemade eggnog typically last in the refrigerator?
Homemade eggnog, due to its fresh ingredients and lack of preservatives, typically lasts for a shorter period compared to store-bought versions. Properly stored in an airtight container in the refrigerator, homemade eggnog is generally safe to consume for about 2 to 3 days. After this timeframe, the risk of bacterial growth significantly increases, potentially leading to foodborne illness.
Pay close attention to any changes in smell, color, or texture. If the eggnog develops a sour odor, noticeable discoloration, or a curdled consistency, it should be discarded immediately, regardless of the 2-3 day timeframe. These are clear indicators of spoilage and should not be ignored.
How long does store-bought eggnog last in the refrigerator, both before and after opening?
Unopened store-bought eggnog, if stored properly in the refrigerator, will generally remain safe to consume until the “use by” or “sell by” date printed on the carton. This date represents the manufacturer’s estimate of peak quality, but the eggnog might still be safe for a short period after that date, assuming it has been consistently refrigerated. However, it’s best to consume it by the printed date for optimal taste and safety.
Once opened, store-bought eggnog should be consumed within 5 to 7 days. Always keep it refrigerated in its original container or a sealed alternative. After this period, the risk of bacterial contamination increases, and the quality of the eggnog may deteriorate, affecting its flavor and texture. Checking for any signs of spoilage, such as a sour smell or change in consistency, is always a good practice.
What are the key signs that eggnog has gone bad?
Several visual and olfactory cues can indicate that eggnog has spoiled. Look for changes in color, such as a brownish or grayish tinge, or the presence of mold. Noticeable changes in texture, like a curdled or lumpy consistency, are also red flags. These are all visual indications that microorganisms have compromised the eggnog’s safety.
More importantly, pay attention to the smell. Eggnog that has turned bad often has a sour, fermented, or otherwise off-putting odor. If you notice any of these signs, it is best to discard the eggnog immediately, even if it is still within the recommended storage timeframe. Tasting spoiled eggnog can lead to foodborne illness.
Can you freeze eggnog, and if so, how long does it last in the freezer?
Yes, eggnog can be frozen to extend its shelf life, but be aware that freezing can alter the texture slightly. Properly frozen eggnog can last for about 2 to 3 months in the freezer. It is crucial to store it in an airtight, freezer-safe container, leaving some headspace to allow for expansion during freezing.
Thawing the eggnog should be done gradually in the refrigerator for the best results. Once thawed, it may have a slightly thinner consistency compared to its original state. Stir it well before serving. Remember to consume the thawed eggnog within a few days and do not refreeze it.
Does the alcohol content in eggnog affect its shelf life?
Yes, the presence of alcohol in eggnog can contribute to a slightly longer shelf life, but it doesn’t eliminate the need for proper refrigeration and adherence to recommended storage times. Alcohol acts as a mild preservative, inhibiting the growth of some bacteria and molds that can cause spoilage.
However, the amount of alcohol typically used in eggnog recipes is not sufficient to provide significant long-term preservation. Homemade eggnog, even with added alcohol, still requires refrigeration and should be consumed within a few days. Store-bought versions, while potentially benefiting slightly from the alcohol content, should still be handled according to the manufacturer’s instructions.
What is the best way to store eggnog in the refrigerator to maximize its shelf life?
The key to maximizing the shelf life of eggnog in the refrigerator is to store it properly in an airtight container. If you are using homemade eggnog, transfer it from the mixing bowl to a clean, sealed container as soon as it has cooled down. Store-bought eggnog should be kept in its original carton, tightly closed.
Ensure your refrigerator is set to a temperature of 40°F (4°C) or below. This temperature range helps to slow down bacterial growth. Also, avoid leaving eggnog at room temperature for extended periods. Always return it to the refrigerator promptly after serving to maintain its quality and safety.
Is it safe to consume eggnog that has been left out at room temperature for more than two hours?
No, it is generally not safe to consume eggnog that has been left out at room temperature for more than two hours. This falls under the “danger zone” (40°F – 140°F or 4°C – 60°C), where bacteria multiply rapidly. Eggnog, being a dairy-based product, is particularly susceptible to bacterial contamination at room temperature.
Consuming eggnog that has been left out for an extended period significantly increases the risk of foodborne illness. Even if the eggnog looks and smells fine, harmful bacteria may still be present. It is always best to err on the side of caution and discard the eggnog if it has been left unrefrigerated for more than two hours.
