How Long Does Wasabi Last?

Last Updated on October 4, 2022 by Lauren Beck

Wasabi is a popular condiment used in Japanese cuisine. It has a strong, pungent flavor that can add a kick to any dish. But how long does wasabi last?

Properly stored, wasabi will last for 3-6 months. However, the lifespan of wasabi depends on how it is packaged. Wasabi paste in a tube can last up to 12 months, while wasabi powder has a shelf life of 2-3 years.

Wasabi is best stored in the refrigerator, in an airtight container. If you are using wasabi paste, it can be helpful to keep it in the freezer, as this will extend its shelf life.

When stored properly, wasabi will retain its flavor and color. However, over time it may lose some of its potency. If your wasabi starts to lose its flavor, you can add a little lemon juice or to give it a boost.

What is Wasabi?

Wasabi (scientific name: Eutrema wasabi) is a plant that belongs to the cruciferous family. The wasabi plant is native to Japan, where it is used as a condiment in traditional cuisine.

The root of the wasabi plant is grated and used as a paste or powder. This pungent condiment is used to add flavor to sushi, sashimi, and other Japanese dishes.

Wasabi has a strong, spicy flavor that can clear your sinuses. It is also known for its antibacterial properties [1].

How to Tell if Wasabi Is Bad?

Wasabi paste or powder can last for 3-6 months, but the shelf life will depend on how it is packaged. If you are using wasabi paste from a tube, it can last up to 12 months.

You can tell if your wasabi has gone bad if it has changed color or texture. Wasabi paste that is starting to turn brown or gray is no longer fresh and should be discarded.

If your wasabi powder has clumped together, it has also gone bad and should be thrown out.

Tips To Store Wasabi

Here are some tips to help you store wasabi and extend its shelf life:

  • Store wasabi in the refrigerator, in an airtight container.
  • If you are using wasabi paste, keep it in the freezer. This will help to extend its shelf life.
  • Wasabi powder can be stored at room temperature, in a cool, dark place.
  • Add a little lemon juice to wasabi paste or powder that has lost its flavor. This will help to refresh it.
  • Make sure to tightly seal the container after each use, to prevent wasabi from drying out.

What is the risk of consuming expired Wasabi?

Wasabi that has gone bad will not be harmful to consume. However, it will no longer have the same flavor or potency. Expired wasabi paste may also have a different color or texture. If you are not sure whether your wasabi is still good, it is best to discard it.

Can you freeze wasabi?

Yes, you can freeze wasabi. Wasabi paste and powder can both be frozen, in an airtight container. This will help to extend their shelf life. When you are ready to use the wasabi, thaw it in the refrigerator overnight. Do not try to thaw wasabi at room temperature, as this will cause it to lose its flavor.

How can you tell real wasabi?

Here are some tips to help you tell if your wasabi is real:

  • Look for wasabi that has a bright green color. If the color is dull, it may be an indication that the wasabi is old.
  • Wasabi should have a strong, pungent flavor. If it tastes bland or weak, it is not fresh.
  • Wasabi paste should be smooth, with no lumps. If it is lumpy or has a grainy texture, it has gone bad.

When buying wasabi powder, make sure to check the label. Real wasabi powder will be made from 100% wasabi root. If the powder contains other ingredients, such as horseradish or mustard, it is not real wasabi.

Is wasabi gluten-free?

Yes, wasabi is gluten-free. This makes it a great alternative for those who are celiac or have a gluten intolerance.

What are some uses for Wasabi?

  • Wasabi can be used in a variety of ways:
  • Wasabi paste can be used as a condiment, added to sushi or sashimi.
  • Wasabi powder can be used to make wasabi paste, or added to sauces, dressings or marinades.
  • Wasabi paste can also be used as a natural remedy for toothaches or sore throats.


Wasabi is a versatile condiment that can be used in many different ways. It has a strong, pungent flavor and can last for several months when stored properly. When buying wasabi, look for wasabi that is bright green in color and has a strong flavor. Wasabi powder should be made from 100% wasabi root and should be stored in a cool, dark place.
