Almond milk has become a staple in many households, offering a dairy-free alternative for those looking to reduce their lactose intake or follow a vegan diet. However, one of the most common questions about almond milk is how long it will keep. The shelf life of almond milk depends on several factors, including the type of almond milk, storage conditions, and whether it has been opened or not. In this article, we will delve into the details of almond milk’s shelf life, exploring the different types of almond milk, storage methods, and signs of spoilage.
Types of Almond Milk and Their Shelf Life
There are several types of almond milk available in the market, each with its own unique characteristics and shelf life. The main types of almond milk include:
Shelf-Stable Almond Milk
Shelf-stable almond milk is packaged in aseptic cartons or bottles and can be stored at room temperature for up to 12 months. This type of almond milk has been ultra-pasteurized, which involves heating the milk to a high temperature to kill off bacteria and extend its shelf life. Shelf-stable almond milk is convenient and can be stored in the pantry or cupboard, making it a great option for those who want to stock up.
Refrigerated Almond Milk
Refrigerated almond milk, on the other hand, is packaged in cartons or bottles and must be stored in the refrigerator at a temperature of 40°F (4°C) or below. This type of almond milk has a shorter shelf life than shelf-stable almond milk and typically lasts for 7-10 days after opening. Refrigerated almond milk is a good option for those who want a fresher taste and are willing to consume it within a shorter period.
Homemade Almond Milk
Homemade almond milk is made by blending almonds with water and straining the mixture to create a milk-like consistency. This type of almond milk has a very short shelf life and typically lasts for 3-5 days when stored in the refrigerator. Homemade almond milk is a great option for those who want to control the ingredients and flavor of their almond milk, but it requires more maintenance and planning.
Storage Methods and Shelf Life
Proper storage is crucial to extending the shelf life of almond milk. Here are some storage methods and their effects on shelf life:

Signs of Spoilage
It is essential to check almond milk for signs of spoilage before consuming it. Here are some common signs of spoilage:
Off Smell or Taste
If almond milk has an off smell or taste, it is likely to have gone bad. Check the milk for any unusual odors or flavors, and discard it if it smells or tastes sour or unpleasant.
Slime or Mold
If you notice any slime or mold on the surface of the almond milk or on the inside of the carton or bottle, it is a clear sign of spoilage. Discard the milk immediately and clean the storage container thoroughly.
Separation or Curdling
Almond milk can separate or curdle over time, especially if it is not shaken well before consumption. However, if the separation or curdling is excessive or accompanied by an off smell or taste, it may be a sign of spoilage.
Conclusion
In conclusion, the shelf life of almond milk depends on several factors, including the type of almond milk, storage conditions, and whether it has been opened or not. Shelf-stable almond milk can last for up to 12 months, while refrigerated almond milk typically lasts for 7-10 days after opening.
