How long can oat milk last in the fridge

Oat milk can last in the fridge for up to 7 to 10 days after opening, depending on several factors, including storage conditions and whether it’s homemade or commercial. It’s important to check the expiration date on the packaging and ensure it is refrigerated properly after each use.

If you’ve made oat milk at home, it’s best consumed within 3 to 5 days. Always store it in a clean, airtight container to maintain freshness. If you notice any changes in color, smell, or taste, it’s safer to discard it.


Longer shelf life with unopened containers

Unopened oat milk can last much longer—typically up to 6 to 12 months when stored in a cool, dry place. This is due to the UHT (ultra-high temperature) processing used in many commercial brands, which kills bacteria and extends shelf life.

Signs that oat milk has gone bad

  • Odor: An off or sour smell is a clear indication of spoilage.
  • Texture: If the oat milk becomes lumpy or separates significantly, it’s best to throw it away.
  • Taste: If it tastes sour or has an unusual flavor, it’s not safe to drink.

Best practices for storage

To maximize the shelf life of oat milk, consider the following tips:

  • Keep it in the coldest part of your fridge, typically near the back.
  • Always seal containers tightly after use.
  • Avoid leaving oat milk out at room temperature for extended periods.
