However, since it’s a fermented product and contains lots of salt, its shelf life is quite long. You can even consume expired gochujang as long as it doesn’t have any signs of spoilage.

Shelf life of Gochujang

The shelf life of Gochujang depends on several factors, including the manufacturing date, the conditions in which it is stored, and how it has been handled. On average, Gochujang has a shelf life of 1-2 years, but with proper storage, it can last even longer.

📝 Factors Affecting the Shelf Life of Gochujang:

  • Temperature: High temperatures can cause Gochujang to spoil more quickly, while lower temperatures can help to extend its lifespan.
  • Air exposure: Oxygen can cause the fermentation process to speed up, leading to spoilage.
  • Sunlight: Direct exposure to sunlight can cause Gochujang to deteriorate more quickly.

Storing Gochujang correctly is key to extending its lifespan. To do so, it is important to keep it in a cool, dark place, away from direct sunlight and heat sources

It is also a good idea to keep the lid tightly closed to prevent air from entering the container. If stored correctly, Gochujang should last for 1-2 years or even longer.

Does Gochujang Need To Be Refrigerated?

Yes, Gochujang needs to be refrigerated after opening the box.

This will help preserve its quality and prevent spoilage. 

The expiration date of the store-bought gochujang ranges from 12 to 18 months. If there is no date on the box, then it is suggested to use the paste within 3 months of opening, provided it is refrigerated. 

Gochujang should be sealed tightly and kept away from heat and direct sunlight.

Signs of Gochujang Going Bad

Gochujang has a relatively long shelf life, but over time, it may start to deteriorate and go bad. If you are unsure whether your Gochujang is still safe to consume, there are several signs to look out for.

#1 Changes in Color, Texture, and Aroma

If the Gochujang has changed color, become thicker or thinner in texture, or has an off aroma, it may have gone bad. A fresh batch of Gochujang should have a deep red color, a smooth texture, and a tangy, slightly fermented aroma.

#2 Presence of Mold or Unusual Growth

If you notice any mold or unusual growth on the surface of the Gochujang, it is best to discard it as it may have become contaminated.

#3 Off-taste or Smell

If the Gochujang has an off taste or smell, it is likely that it has gone bad. The flavor of Gochujang should be slightly spicy, tangy, and slightly fermented. If it tastes or smells sour, rancid, or otherwise off, it is best to discard it.

If you notice any of these signs, it is best to discard the Gochujang and purchase a fresh batch. 

While Gochujang is relatively safe to consume, consuming spoiled Gochujang can lead to food poisoning and other health issues.

Impact of Temperature, Air Exposure, and Sunlight

The quality of Gochujang can be greatly affected by temperature, air exposure, and sunlight. Understanding these factors is important for storing Gochujang correctly and avoiding spoilage.

High heat can cause the paste to separate and change in texture, flavor, and aroma.

#2 Air Exposure

Gochujang is a fermented product and is sensitive to air exposure. Oxygen can cause the product to spoil more quickly, as well as cause the flavor and aroma to change.

To prevent air exposure, store the Gochujang in an airtight container.

#3 Sunlight

Direct exposure to sunlight can cause Gochujang to deteriorate more quickly. Sunlight can cause the product to change in color, flavor, and aroma.

To prevent sunlight exposure, store the Gochujang in a dark, cool, and dry place.

Differences Between Fresh and Fermented Gochujang

Gochujang can come in either Fresh or Fermented form, and understanding the difference can help you determine the shelf life and quality of your product.

Fermented Gochujang

Fermented Gochujang is made with a mixture of chili paste, rice powder, and other ingredients that have been fermented for several months.

Fermented Gochujang has a longer shelf life, usually lasting up to a year or more if stored correctly.

To determine if your Gochujang is fresh or fermented, check the label or ingredients list. Fresh Gochujang will have a milder flavor and a sweeter taste, while fermented Gochujang will have a more intense flavor with a spicy and tangy taste.

The impact of fermentation on the shelf life of Gochujang is significant. Fermentation helps to preserve the product, making it last longer and retain its flavor for a longer period of time. Whether you prefer fresh or fermented Gochujang, it is important to store it correctly to extend its shelf life and maintain its quality.
