Is It Safe to Drink Expired Almond Milk?
Understanding the Risks
When it comes to almond milk, consumers are often cautious about its shelf life and safety after the expiration date. Almond milk, a popular dairy alternative, is known for its longer shelf life compared to cow's milk, but it still raises concerns once the printed date on the carton has passed. The shelf stability of almond milk can vary depending on whether it is commercially prepared and pasteurized or homemade, and whether it has been stored refrigerated or at room temperature.
Commercially produced almond milk typically comes with two types of expiration dates, viz., a 'best by' date for unopened shelf-stable cartons and a recommended consumption timeframe for once the carton is opened, generally ranging from 5 to 10 days when properly refrigerated. It is crucial to understand that the 'best by' date is an indicator of optimal quality set by manufacturers and does not always equate to the product being unsafe post that date. However, consumers are advised to assess the milk through smell, taste, and visual inspection for any signs of spoilage before consumption.
On the other hand, homemade almond milk lacks the preservatives found in commercial varieties and thus has a much shorter window of freshness, usually 3 to 5 days in the refrigerator. It is important that individuals rely on their senses to assess freshness and to err on the side of caution, as almond milk can spoil and host bacteria that are harmful if consumed. The proper storage of almond milk, keeping it at a consistent refrigerated temperature, plays a fundamental role in extending its consumable life.

Maintaining a consistent temperature is crucial for the longevity of almond milk. A refrigerator set at or below 40°F is ideal. Temperature fluctuations should be minimized as they can accelerate spoilage and promote bacterial growth.
Shelf-Stable vs Refrigerated Almond Milk
Shelf-stable almond milk uses aseptic packaging that allows it to be kept unrefrigerated until opened. Once open, it requires refrigeration and should be used within 7 to 10 days. Refrigerated almond milk, on the other hand, must be kept in the fridge at all times and usually has the same 7 to 10-day window for optimal freshness post-opening.
Shelf Life and Expiration
Understanding the nuances of expiration dates and proper storage can greatly affect the shelf life and safety of consuming almond milk, whether it is commercially produced or homemade.
Expiration Dates and Their Meaning
Expiration dates on commercially made almond milk are guidelines for consumers to ensure quality and freshness. Typically, an expiration date or a best-by date is printed on the packaging, which indicates how long the product is expected to remain at peak quality. It's important to distinguish that a best-by date is not an absolute safety cutoff, but rather a manufacturer's estimate of when the product will no longer be at its best.
Extending Almond Milk's Usability
To extend the usability of almond milk past the expiration date, proper storage is crucial. The USDA suggests that refrigeration at 40 degrees Fahrenheit or below is essential to preserve the milk's quality. Freezing almond milk is an option, although it may alter the consistency, and it is important to leave room for expansion by pouring off a small amount before freezing.
Commercial and Homemade Almond Milk Shelf Life
Commercially prepared almond milk generally offers a longer shelf life compared to homemade versions, due to pasteurization and added preservatives. An unopened carton of commercial almond milk can last for several months when stored correctly. In contrast, fresh homemade almond milk typically has a shelf life of 3 to 5 days when refrigerated. Whether commercial or homemade, almond milk should be consumed promptly once opened and always checked for signs of spoilage, such as changes in smell, taste, or texture, before use.
