If you’re a sushi lover like me, you’ve probably drizzled wasabi all over your rolls to give them that extra kick. But have you ever wondered how long that jar of wasabi lasts?
Real wasabi, unlike the green paste we often see at restaurants, is made from grated stem of an Asian plant that is difficult to cultivate and expensive to produce. Because of its high cost, most restaurants serve imitation wasabi made from horseradish, mustard, and food coloring.
But for those who have had the pleasure of tasting real wasabi, it’s hard to go back to the imitation stuff. So, if you’ve invested in a tube of real wasabi, you’ll want to know how long it stays fresh. Let’s explore the shelf life of this distinctive condiment.
What is real wasabi?
When you hear “wasabi”, you might immediately think of that bright green, pungent paste that comes alongside your sushi rolls. However, what most people in the Western world know as wasabi is actually a blend of horseradish, mustard, and food coloring. Real wasabi, on the other hand, is a completely different plant altogether.
Real wasabi or Wasabia japonica is a rare and expensive plant that belongs to the Brassicaceae family, which includes mustard and cabbage. It is native to Japan and is grown in cool, mountainous regions with abundant spring water. The plant has green heart-shaped leaves that grow up to 2 feet long, and the coveted rhizome or root can reach up to 6 inches in length and 2 inches in diameter. The rhizome is the part of the plant that is used to make the paste typically consumed alongside sushi, sashimi, and other Japanese dishes.
- Real wasabi has a distinct, complex, and delicate flavor that is not as harsh as the imitation paste. It has a subtle sweetness and a subtle heat, and releases its flavor slowly, offering a different taste profile than its imitation.
- Unlike its fake counterpart, real wasabi does not leave a burning sensation in the mouth, but instead lingers in the nasal cavity for a while. This is because it contains a compound called allyl isothiocyanate, which reacts with the enzymes in our saliva and creates a vapor that travels to the nose, producing a unique sensation.
- Real wasabi is not easy to come by, since it is difficult and expensive to cultivate, and has a very short shelf life once harvested. It loses its flavor and pungency very quickly, even when refrigerated, and therefore needs to be consumed within a few days of grating.
How is Real Wasabi Different from Fake Wasabi?
Real wasabi is a flavorful and highly prized condiment that Japanese cuisine is known for. It is made from the stem of the Wasabia japonica plant, while fake wasabi is usually made from a combination of horseradish, mustard, and food coloring. Here are some key differences between the two:
- Taste: Real wasabi has a nuanced and complex flavor profile. It is earthy, pungent, and slightly sweet, with a subtle heat that lingers in the mouth. In contrast, fake wasabi has a one-dimensional, overpowering horseradish flavor that can overpower other ingredients in a dish.
- Texture: Real wasabi has a delicate, creamy texture that is perfect for spreading or mixing into sauces. In contrast, fake wasabi has a grainy texture that feels abrasive on the tongue.
- Color: Real wasabi is pale green and fades quickly if exposed to oxygen. In contrast, fake wasabi is often bright green and can retain its color for a long time, thanks to artificial coloring.
These differences mean that real and fake wasabi are not interchangeable ingredients, despite their similar appearance. While fake wasabi can be a useful substitute in a pinch, it lacks the subtleties and balance of real wasabi. True wasabi cost more than synthetic wasabi however, it contains more healthful potential benefits than fake wasabi. Therefore, if possible, it is always better to use the real thing.
What are the health benefits of consuming real wasabi?
Real wasabi, unlike the imitation wasabi commonly found in restaurants, is a tremendously healthy food that many people may not be aware of. Below, we will discuss some of the benefits of consuming real wasabi and how it can improve your health.
- Anti-inflammatory properties: Real wasabi contains compounds such as isothiocyanates and polyphenols, which have anti-inflammatory properties. These compounds can help reduce inflammation in the body and prevent chronic diseases such as heart disease and cancer.
- Antioxidant-rich: Real wasabi is also rich in antioxidants, which help protect the body against oxidative stress caused by harmful free radicals. Antioxidants also play a role in reducing inflammation and preventing chronic disease.
- Rich source of vitamins and minerals: Real wasabi is a great source of nutrients such as vitamin C, B6, calcium, and magnesium. These vitamins and minerals are important for maintaining good health and preventing disease.
In addition to the benefits listed above, real wasabi also has antimicrobial properties that can help prevent foodborne illness. It may also provide relief from migraines, arthritis, and respiratory problems. However, it is important to note that real wasabi can be difficult to find and can be expensive. Therefore, it may not be feasible for everyone to consume on a regular basis.

What are the different forms of real wasabi available in the market?
If you are a fan of sushi, then you are probably familiar with the paste-like condiment that is often served alongside your favorite rolls. However, not all wasabi is created equal. In fact, most of the “wasabi” you’ll find in the market is actually a mixture of horseradish, mustard, and green food coloring. Genuine wasabi is much rarer and more expensive, but it also has a more nuanced flavor and a range of different forms to choose from.
- Fresh Wasabi: The most authentic form of wasabi is freshly grated from the plant’s stem. The rhizome of the wasabi plant (Wasabia japonica) is notoriously difficult to grow and must be carefully tended and harvested by skilled farmers. As a result, fresh wasabi is quite rare and can be very expensive. However, it has a more complex and subtle flavor than the imitation wasabi you’ll find in most restaurants.
- Wasabi Powder: For a more affordable option, many people turn to wasabi powder. This is made from dehydrated wasabi root and must be reconstituted using water. The taste of wasabi powder can be quite strong, so it’s best to start with a small amount and add more to taste.
- Prepared Wasabi: Similar to the synthetic wasabi you may be used to, prepared wasabi is a mixture of horseradish, mustard, and green food coloring. However, some brands do include genuine wasabi in their blends. Prepared wasabi comes in tubes or jars and can be found in most grocery stores or online. While it’s not as high-quality as fresh wasabi, it can still add a kick of flavor to your favorite dishes.
Depending on your budget and personal preference, there are a variety of different forms of real wasabi to choose from. Whether you opt for the subtle complexity of fresh wasabi or the affordability of wasabi powder or prepared wasabi, adding this flavorful condiment to your meals can elevate your dining experience.
How to Prepare Real Wasabi?
Preparing real wasabi can be a bit intimidating for first-timers, but once you get the hang of it, it’s a pretty straightforward process. Here’s a step-by-step guide to help you prepare your own fresh wasabi:
- Start by washing the fresh wasabi rhizome under cold running water. This will help remove any excess dirt or debris from the surface.
- Next, use a sharp knife or a wasabi grater to grate the rhizome into a fine paste. You can use a traditional Japanese sharkskin grater or a more modern stainless steel one. If you’re using a knife, make sure to finely chop the wasabi into tiny pieces.
- As you’re grating or chopping the wasabi, make sure to keep it moist by sprinkling a small amount of water over the surface. This will help bring out the flavor and aroma of the wasabi.
- Once you’ve grated or chopped the wasabi, let it sit for a minute or two to develop its heat and flavor. This is an important step, as the longer you let the wasabi sit, the hotter it will become.
- Finally, transfer the wasabi paste to a small bowl and serve it immediately. Wasabi loses its flavor and heat rapidly, so it’s best to consume it within a few hours of preparation.
The Importance of Fresh Wasabi
If you’re wondering why fresh wasabi is so highly prized among connoisseurs, the answer is simple: it tastes better! While some people have grown accustomed to the taste of imitation wasabi, there’s really no comparison to the complex, nuanced flavor of the real thing.

Storing Fresh Wasabi
If you have any leftover wasabi, it’s important to store it properly to prevent it from spoiling. Unlike the powdered wasabi that comes in a tin, fresh wasabi paste needs to be kept refrigerated and consumed within a few days of preparation. To help preserve the flavor and texture of the wasabi, wrap it in plastic wrap or place it in an airtight container before storing it in the fridge.
| Storage Method | Storage Time |
|---|---|
