How Long Does Almond Milk Last in the Fridge?
Refrigerator Shelf Life & Spoilage Guide
Almond milk lasts 7-10 days in the refrigerator after opening.
Once you break the seal on a carton of almond milk, the clock starts. While unopened shelf-stable versions can last months, opened almond milk must be refrigerated and typically stays fresh for 7 to 10 days. Fresh almond milk is characterized by a mild aroma, a smooth consistency, and an even ivory color. Because it is a plant-based beverage, spoilage often manifests as separation that cannot be shaken out or a distinct sour smell. To maintain safety and quality, monitor the texture and scent daily; if the liquid becomes chunky, smells off, or the carton swells, discard it immediately.
Heads up: shelf-life ranges are estimates based on home storage. We make no guarantee of accuracy. When unsure, throw it out.

Common questions
How long does almond milk last after opening?
Opened almond milk typically lasts 7-10 days when stored in the refrigerator. To ensure maximum quality and safety, consume it within this window.
Does almond milk need to be refrigerated before opening?
Many almond milks are processed to be shelf-stable until opened. However, once the seal is broken, the product must be refrigerated to prevent rapid spoilage.
Can you freeze almond milk to extend its shelf life?
Yes, almond milk can be frozen, though this often changes the texture and causes separation. If you cannot finish the carton within 10 days, freezing is an option, provided you shake it well after thawing.
What are the signs that almond milk has gone bad?
The primary indicators of spoilage in almond milk are a sour or stale smell, a curdled or grainy texture, and the presence of clumps or visible mold.
Why is my almond milk separating?
Some settling is normal for plant-based milks. If a shake restores the smooth consistency, it is fine. If the separation persists or is accompanied by a sour smell, the milk has likely spoiled.
Sage's Final Word: Keep your almond milk chilled and use it within 7-10 days of opening. Shake for settling, but toss it immediately if you see clumps or smell anything sour.
