Mirin isn’t just good for cooking; it makes a great marinade or sauce when mixed with soy sauce or other seasonings such as garlic and ginger.

Can You Freeze Mirin?

Mirin, a sweet and light rice wine, is an essential ingredient in many Japanese dishes such as yakitori, teriyaki and oden.

If you’ve ever been left with extra mirin after using it in your cooking pursuits, you’ve likely wondered whether you can freeze the remainder for later.

The answer to the question is yes.

Freezing mirin helps preserve its flavor and ensure that it’s ready to use at a moment’s notice when you need an additional dash of sweetness for your next culinary delight.

To freeze mirin, simply pour it into an air-tight container or a freezer-proof bag and seal it off completely.

Once frozen, the beverage will last for up to six months before its quality begins to decline.

How to Tell If Mirin is Bad?

Mirin is a Japanese cooking wine that is made from rice.

It has a sweet taste and is often used in sauces and marinades.

Mirin is safe to consume when it is fresh, but it can go bad over time.

There are a few signs that you can look for to determine if your mirin has gone bad.

The first sign that mirin has gone bad is the color. Fresh mirin should be a clear, golden color.

If the mirin has turned dark brown or black, it has probably gone bad and should not be consumed.

Another sign of bad mirin is the smell. Mirin should have a sweet, slightly alcoholic smell.

If the mirin smells sour or off, it has gone bad and should not be used.

The texture of the mirin can also be an indicator of whether it has gone bad.

Fresh mirin should be thin and watery.

If the mirin is thick or syrupy, it has probably spoiled and should not be consumed.

If you see any of these signs, it is best to discard the mirin and buy a new bottle.

Mirin that has gone bad can cause nausea and vomiting, so it is best to err on the side of caution.


From what we’ve gathered, it seems that Mirin can last for quite some time – even after it’s been opened.

However, it’s important to make sure that you store it properly (in a cool, dark place) to ensure that it doesn’t go bad.

If you’re not sure whether your Mirin is still good, be sure to check for any signs of spoilage (like mold or changes in color/texture).

And if you’re ever in doubt, it’s always better to be safe than sorry – so it might be best to just toss it out.
