What is Gochujang?

Gochujang is an essential condiment when cooking Korean food.

It’s a spicy, sweet, and savory fermented condiment made up of gochugaru (Korean chili peppers), meju powder (fermented soybeans), glutinous rice, salt, and yeotgirum (barley malt powder).

The ingredients are mixed and placed in an earthenware pot outdoors, where it’s left to ferment for many years.

During the fermentation process, the starches from the cooked glutinous rice get converted into sugar which lends the paste its slight sweetness. On the other hand, the gochugaru delivers the heat that the paste is known for, while the fermented soybeans give the paste its trademark umami flavor.

Because of its unique taste, it’s often used to add depth to a wide range of dishes, including braises, stews, sauces, and marinades.

Fun Fact:

Unlike sriracha, gochujang is not a finishing or dipping sauce. It’s best used as a complementary sauce for rich meat dishes like bulgogi.

How Long Does Gochujang Last?

You know by now that gochujang can go bad, but it doesn’t get bad quickly. So with that said, how long can you enjoy gochujang?

An opened tub of gochujang can last for up to two years when stored in the refrigerator. On the other hand, you should start with the best before the date when determining the shelf life of an unopened tub of gochujang.

Pro Tip:

As long as there’s no sign of spoilage and the paste has been properly stored, it’s still safe to consume gochujang even if it’s past the best before date.

How Do You Know If Gochujang Is Bad?

So what are the spoilage signs that you should look for to determine if the gochujang is still safe for consumption? Here are some of them:

1. Changes in Appearance

This is the first sign you can easily spot when you open that tub of gochujang. But, of course, you already know what a good gochujang looks like—it’s like a red sticky cooked glutinous rice.

If the paste already looks slimy or has oil on its surface, you should err on the side of caution and avoid consuming it.

If the paste has turned brown, you should avoid using it too.

2. Mold Growth

And does it have a fuzzy white or green growth on its surface or at the cover of its tub? If yes, then throw it right away. Mold growth is never a good sign.

3. Off Smell

To be honest, it’s hard to describe what gochujang smells like. But what we can do is tell you how it shouldn’t.

If upon opening, the tub gives off a sour or foul smell, it may have already spoiled. If it smells like vinegar, discard it immediately.

4. Weird Taste

If you’re still unsure of its safety after smelling and examining the paste, then you should give it a taste. However, make sure to taste only a small amount of the paste.

It’s normal for the taste of gochujang to change over time. But its flavor will either become milder or stronger, but it shouldn’t have any other unusual taste.

The common taste of spoiled food items is sourness, so throw it away if your gochujang starts to taste like vinegar.

How Do You Store Gochujang Properly?

Since it’s shelf-stable, storing gochujang is easy peasy. However, if the tub is still unopened, it must be stored in a cool, dark, dry place like your kitchen pantry or cabinet.

On the other hand, an opened tub of gochujang must be refrigerated. The cold temperature inside the refrigerator can slow down its spoilage so that you can enjoy the condiment for a long time.

But here’s the most critical storage tip of all: minimize air exposure. When exposed to air, gochujang will become dry and risk bacterial contamination.

Pro Tip:

Place the opened tub in a resealable bag to protect it from the cold air inside the refrigerator.
