How Long Does Vegan Mayo Last?

By Olivia

Vegan mayo is a popular plant-based alternative to traditional mayo, but how long does it last? Just like regular mayo, the shelf life of vegan mayo depends on various factors, including the brand, how it’s stored, and whether it’s opened or unopened. Here’s what you need to know about the longevity of vegan mayo.

1. Unopened Vegan Mayo

If your vegan mayo is still sealed and unopened, it can last quite a while. Most brands of vegan mayo typically have a shelf life of about 6 to 12 months when stored in a cool, dry place like your pantry. It’s important to check the expiration date on the jar or bottle to ensure its freshness.

2. Opened Vegan Mayo

Once you’ve opened a jar or bottle of vegan mayo, its shelf life shortens significantly. After opening, vegan mayo should be refrigerated promptly to maintain its quality and prevent spoilage. Typically, opened vegan mayo can last for about 2 to 3 months in the refrigerator.

3. Signs of Spoilage

It’s crucial to pay attention to any signs of spoilage in vegan mayo. If you notice any unusual color, texture, or smell, it’s best to discard it. Spoiled vegan mayo may have a sour or rancid odor, a slimy texture, or an off-putting appearance. Trust your senses and prioritize food safety.

4. Homemade Vegan Mayo

Many people enjoy making their own vegan mayo at home using ingredients like plant-based milks, oils, and seasonings. Homemade vegan mayo typically has a shorter shelf life compared to store-bought options. It’s recommended to consume homemade vegan mayo within 3 to 5 days when stored in the refrigerator.

5. Extending Shelf Life

If you want to extend the shelf life of your vegan mayo, there are a few tips you can follow:

  • Always store vegan mayo in the refrigerator, even when unopened.
  • Ensure the lid or cap is tightly sealed after each use.
  • Use clean utensils to scoop out mayo to avoid contamination.
  • Keep the mayo away from heat, sunlight, or moisture.

By following these guidelines, you can help prolong the lifespan of your vegan mayo and reduce the risk of spoilage.


In conclusion, unopened vegan mayo can last for around 6 to 12 months, while opened vegan mayo should be consumed within 2 to 3 months. Pay attention to any signs of spoilage and discard it if it appears or smells off. Homemade vegan mayo has a shorter shelf life and should be consumed within 3 to 5 days. By storing vegan mayo properly and following good food safety practices, you can enjoy its creamy goodness for longer.
