Is Wasabi Hot? (Is It Spicy or the Spice? Explained!)

We tend to think that wasabi is hot. But is it? I’ll tell you.

Is wasabi hot? Yes, wasabi is hot. But it’s a very unique flavor that is very mild and not at all spicy. The heat from wasabi comes on quickly but fades just as fast. So while it may be hot, it’s not going to last long or linger on your tongue as other spices might.

Let’s get more into this!

Is wasabi considered hot?

Wasabi doesn’t burn or sting at all. It’s not spicy at all. It only tastes like a mild condiment with a bit of heat and the characteristic pungency of mustard (or horseradish). But we can say that wasabi is considered hot.

Wasabi can make you go green when it first touches your tongue, but the heat is in the aftertaste and not so much in the initial hit.

This makes for an interesting paradox when it comes to teaching people about wasabi—you want to explain it before they taste it because this will help them understand its unique flavor profile, but then you want to wait until your guest has had an opportunity to experience its potent punch before telling them that wasabi isn’t hot at all.

Is wasabi hot to taste?

Yes, wasabi is hot to taste. It’s caused by the same compounds that make mustard and horseradish hot, which is allyl isothiocyanate. When wasabi hits your tongue, you’ll experience a sharp, pungent flavor followed by a burning sensation in your nose.

In addition to the heat, wasabi also has a strong, pungent flavor that is similar to mustard or horseradish. It’s this flavor that can make people tear up when they eat.

Is wasabi hot or spicy?

Wasabi is hot, not spicy.

Although the plant used to make wasabi is related to horseradish and mustard (but not nearly as biting), the heat sensation is different from the heat of chilis. Chilies are “hot” in a rather literal sense:

They activate the pain receptors of your tongue, causing a burning sensation that spreads through your mouth, throat, and head. Wasabi doesn’t do this – it contains no capsaicin so it can be eaten by people with allergies or sensitivities to chilis.

Is wasabi spicy or bitter?

Now, we know that wasabi is hot, but what about bitter? While you might think that wasabi is spicy and bitter at the same time (the way some people mistakenly describe it as spicy and sweet), this isn’t actually true. In fact, bitter and spicy are literally two different types of tastes!

Bitter tastes are detected by the taste buds on the back of your tongue. Spicy tastes are detected by a different set of nerve endings on the roof of your mouth. So if you’ve noticed that wasabi tastes hot but not bitter, you’re totally right!

Is wasabi spicy or sweet?

There are many things that are sweet. There are even more things that are spicy. But you will never, ever come across a combination of the two—at least not with wasabi.

The answer to “is wasabi hot?” is… yes! If you’ve had it before, you know it is spicy (and if you haven’t had it before, trust us—it is!).

Wasabi can be compared to real horseradish, which also possesses a unique bite and flavor that may lead some people to believe it could be sweet (after all, horseradish sauce often accompanies sweetmeats like ham at Easter).

But in the end, wasabi is definitely not sweet.

Is real wasabi hot?

Yes, real wasabi is hot, but it’s a very mild flavor. The real wasabi is a root of the Wasabia japonica plant, and it’s native to Japan. The root is used to make a paste, which is then served with sushi or sashimi.

The flavor of wasabi is unique, and it’s hard to describe if you’ve never had it before. It’s not spicy like chili peppers, but it does have a bit of heat and a strong, pungent flavor.

Fresh wasabi is also a little bit hot, but the flavor is very mild and delicate. If you’re used to eating sushi with the green paste served on the side in small amounts, then you’re probably not familiar with just how flavorful and powerful fresh wasabi can be when experienced properly.

Is all wasabi hot?

Despite what you’ve been told, wasabi isn’t really all that hot.

It might have a potent kick if you eat too much wasabi at once, but wasabi is actually milder than raw horseradish.

Instead of being a spice, wasabi is an herb and plant root that grows natively in Japan, where it has been used as a flavoring for hundreds of years.

Is wasabi sauce spicy?

Yes, wasabi sauce can be spicy. The spiciness of wasabi sauce depends on the amount of wasabi powder or paste used to make it.

Wasabi sauce is a sauce made from wasabi (or horseradish) and other ingredients such as mayonnaise, soy sauce, and sesame oil. The spiciness of wasabi sauce depends on the type of ingredients and the ratio in which they are mixed together.

Why do people think wasabi is spicy?

It is reasonable that people would be confused about the nature of wasabi. There are a few reasons for this, the first being its bright green color.

The idea that spicy things are hot and firey-red has been implanted in our brains since we were kids, and it’s easy to make the mental leap to assume that something as green as wasabi must have some heat when you put it in your mouth.

The second reason is that wasabi is often served in small amounts as a condiment, and it’s easy to overdo it when you’re adding more to your plate. A little bit of wasabi goes a long way, and if you eat too much of it at once, the heat can be overwhelming.


The next time you eat sushi or other Japanese food and spot a dab or mound of green stuff on your plate, give it a try. It may not be as hot as you expect, but it will add an interesting flavor note that can enhance your meal.
