Is it safe to drink unopened pasteurized apple cider after the date?

It's generally not recommended to drink unopened pasteurized apple cider after the "best by" or "use by" date, even though it's pasteurized.

Here's why:

* Pasteurization doesn't guarantee indefinite shelf life: While pasteurization kills most harmful bacteria, it doesn't eliminate all microorganisms. Over time, some bacteria might still survive and grow, potentially affecting the taste, quality, and safety of the cider.

* "Best by" dates are guidelines: They indicate the best time to consume the cider for optimal flavor and freshness. After the date, the cider might start to lose its flavor and become less enjoyable.

* Varying storage conditions: The "best by" date assumes proper storage (refrigeration). If the cider wasn't stored properly, it might spoil faster.

However, if the cider has been stored in the refrigerator consistently and the bottle shows no signs of damage or spoilage (like discoloration, cloudiness, or a sour smell), you might be able to consume it after the date. It's best to taste a small amount first to assess its flavor and safety.

If you are unsure, it's always best to err on the side of caution and discard the cider.

Remember, it's always best to follow the manufacturer's instructions and use your best judgment.
