As an expert sommelier and brewer, I can provide you with some insights into the shelf life of eggnog once it has been opened. It’s important to note that the shelf life can vary depending on whether the eggnog is store-bought or canned.
Store-bought eggnog typically has a shorter shelf life compared to canned eggnog. Once you open a carton of store-bought eggnog, it is generally recommended to consume it within 5-7 days if it has been refrigerated. This is because store-bought eggnog often contains dairy products, such as milk and cream, which can spoil relatively quickly.
To ensure the longevity of your store-bought eggnog, it’s essential to store it in the refrigerator at a temperature below 40°F (4°C). This helps to slow down the growth of bacteria and extend its shelf life. If you leave the eggnog at room temperature for an extended period, it can spoil much faster.
On the other hand, canned eggnog tends to have a longer shelf life. Typically, canned eggnog can last for about 4 to 5 months if stored in a cool and dry place. It’s important to check the expiration date on the can to ensure its freshness. Once opened, canned eggnog can last for around 5-7 days if stored properly in the refrigerator.
Canned eggnog often undergoes a process of pasteurization, which helps to kill any potentially harmful bacteria and extends its shelf life. This process involves heating the eggnog to a specific temperature to eliminate bacteria without affecting the taste and quality. However, once the can is opened, it is exposed to the environment, and the shelf life becomes more limited.
To maximize the shelf life of canned eggnog after opening, it’s crucial to transfer the remaining eggnog to an airtight container and store it in the refrigerator. This helps to maintain its freshness and prevent contamination. Avoid leaving the eggnog at room temperature for too long, as it can lead to spoilage.
It’s important to use your senses to determine if the eggnog is still good to consume. If you notice any off smells, changes in texture, or unusual flavors, it’s best to discard the eggnog to avoid any potential foodborne illnesses.
The shelf life of eggnog after opening can vary depending on whether it is store-bought or canned. Store-bought eggnog typically lasts 5-7 days in the refrigerator after opening, while canned eggnog can last for about 5-7 days after opening if properly stored. Remember to always check the expiration dates and use your senses to ensure the eggnog is still fresh and safe to consume.
