What is Gochujang and How is it made?
Gochujang is a popular Korean condiment that is known for its spicy and savory flavor. It is often referred to as a chili paste and is a staple in Korean cuisine. Made from fermented soybeans, red chili powder, glutinous rice, and salt, gochujang has a unique and complex taste that adds depth and heat to dishes.
The process of making gochujang starts with soaking glutinous rice in water overnight. The rice is then cooked until it becomes soft and sticky. Once cooked, the rice is mixed with red chili powder and fermented soybean powder. This mixture is then placed in a clay pot and left to ferment for several months.
During the fermentation process, the mixture develops its distinct flavor and aroma. The enzymes present in the soybeans and rice break down starches into sugars, which then undergo further fermentation by lactic acid bacteria. This fermentation process not only adds flavor to the gochujang but also contributes to its thick and smooth texture.
After the fermentation period, the gochujang is usually blended to achieve a smooth consistency. Some variations of gochujang may also include additional ingredients such as garlic, ginger, or sugar to enhance the flavor profile. The final product is a thick and sticky paste with a deep red color.
Gochujang is a versatile ingredient that can be used in a variety of dishes. It is often used as a base for Korean stews and soups, such as kimchi jjigae or tteokbokki. It can also be used as a marinade for meat or seafood, or simply as a dipping sauce. Its spicy and umami-rich flavor makes it a favorite among Korean food enthusiasts around the world.

Differences between Fresh and Fermented Gochujang

There are two main types of gochujang: fresh and fermented. While they may seem similar, there are some key differences between the two.
Firstly, the main difference between fresh and fermented gochujang lies in the fermentation process. Fresh gochujang is made by combining the ingredients and using them immediately. This results in a bright red color and a strong, spicy flavor. On the other hand, fermented gochujang undergoes a longer fermentation period, allowing the flavors to develop and mellow over time. This results in a deeper red color and a more complex, umami-rich taste.
Another difference between fresh and fermented gochujang is their texture. Fresh gochujang tends to have a smoother consistency with a slightly grainy texture due to the presence of ground rice. It is thick but still easy to spread or mix into dishes. Fermented gochujang, on the other hand, has a thicker and stickier texture. As it ages, it becomes even thicker and can be quite sticky, making it perfect for marinades or glazes.
Finally, fresh and fermented gochujang also differ in their shelf life. Fresh gochujang has a shorter shelf life than its fermented counterpart.
Benefit of Gochujang
Gochujang is not only a delicious condiment, but it also contains probiotic bacteria which are beneficial for the digestive system. The fermentation process also helps to preserve the gochujang and extend its shelf life. Additionally, there are potential health benefits associated with consuming foods that contain probiotics. These include improved digestion, better nutrient absorption, and a stronger immune system.
Additionally, gochujang is a great source of vitamins and minerals such as vitamin B6, iron, magnesium, and folate. These nutrients are important for maintaining good health and can help to prevent certain illnesses. Furthermore, gochujang is low in calories and fat-free making it an ideal ingredient for those who are looking to watch their calorie or fat intake.
Does Gochujang Go Bad?
Fermented gochujang:
Similar to other food products, proper storage is crucial to prevent gochujang from spoiling or deteriorating over time. The shelf life of gochujang depends on factors such as brand, ingredients, and storage conditions. Generally, an unopened jar of gochujang can last up to 2 years when stored in a cool, dry place.
Once opened, it should be stored in the refrigerator and is best consumed within 6 months. If you notice any changes in color or texture, or if there is a foul smell coming from the jar, it is likely that the gochujang has gone bad and should be discarded.
Fresh gochujang:
Fresh gochujang is more perishable than its fermented counterpart and should be used within a few weeks of opening. It is best to store it in the refrigerator and use it as soon as possible. As long as it has been properly stored, fresh gochujang can last up to 2 months if unopened.
Factors that Affect the Shelf Life of Gochujang
- Brand: Different brands of gochujang may have different shelf lives.
- Ingredients: The list of ingredients in the gochujang could affect its longevity.
- Storage conditions: Proper storage conditions can help keep gochujang fresh for longer.
- Expiration date: Be sure to check the expiration or best by date on the gochujang packaging.
Signs that Gochujang has Gone Bad:
- Mold – Keep an eye out for any white, black, or green spores on the surface of your gochujang. If you spot any, it’s a clear indication that it has spoiled and should be discarded immediately.
- Off smell or color – Pay attention to any unusual odor or a change in color. Bad gochujang may emit an unpleasant smell and appear different in color compared to its usual vibrant hue.
- Clumps or chunks – Another sign of spoilage is the formation of clumps or chunks in your gochujang. If the texture has become lumpy or uneven, it’s a good indication that it has gone bad.
- Taste – When tasting gochujang, a sour or bitter flavor can be a strong indicator of spoilage. If it doesn’t taste like its usual savory and slightly sweet profile, it’s best to avoid consuming it.
By being aware of these detailed signs, you can ensure the freshness and quality of your gochujang for a delightful culinary experience.
Is it Safe to Consume Gochujang that has Gone Bad?
For safety reasons, we strongly advise discarding any gochujang that you suspect may have gone bad. Consuming gochujang that is spoiled or past its prime could potentially lead to food poisoning or other gastrointestinal issues. It’s always better to err on the side of caution when it comes to your health and well-being.
How to Proper Storage of Gochujang?
Proper storage of gochujang can help extend its shelf life and maintain its freshness. Here are some tips to store gochujang correctly:
One of the key factors in storing gochujang is to keep it in a cool and dark place. The ideal temperature for storing gochujang is between 50°F (10°C) and 68°F (20°C). Exposure to direct sunlight or heat can cause the gochujang to spoil or lose its flavor. Therefore, it is best to store it in a pantry or cupboard away from any sources of heat or light.
Another important aspect of storing gochujang is to keep the jar tightly sealed. Gochujang is a fermented product, which means it contains live microorganisms that help develop its unique flavors. However, exposure to air can lead to bacterial growth and spoilage. It is recommended to use a jar with an airtight lid or transfer the gochujang into an airtight container if the original packaging is not sufficient.
Additionally, it is advisable to avoid contaminating the gochujang with any moisture or foreign substances. This can be achieved by using a clean utensil each time you scoop out some gochujang from the jar. Avoid using fingers or dirty spoons as they can introduce moisture and bacteria into the paste. It is also important to wipe the rim of the jar before sealing it to remove any residue that could potentially lead to spoilage.
How to Choose Best Gochujang?
When shopping for gochujang, it is important to check the ingredients list as well as the expiration date. Quality gochujang should contain only natural ingredients and not include any preservatives or artificial colors. Additionally, fresh gochujang should have a vibrant red color and a pungent yet sweet aroma. Be sure to read reviews of the product and choose one with a good track record.
For those looking for added convenience, there are now many brands of ready-to-use gochujang available in supermarkets or online stores. These pre-made versions often come in convenient squeeze bottles which can be used directly without any preparation. However, these products tend to have shorter shelf lives, so it is important to check the expiration date before purchase.
How to Make Gochujang Sauce at Home?
Making Gochujang sauce at home allows you to customize the ingredients and control the level of spiciness to suit your taste buds. While there are various recipes available, here is a simple and easy method to make Gochujang sauce at home.
To start, gather the necessary ingredients: 1 cup of Korean red pepper flakes, 1 cup of glutinous rice powder, ½ cup of fermented soybean paste, ½ cup of water, ¼ cup of sugar, 3 tablespoons of soy sauce, 3 tablespoons of minced garlic, and 2 tablespoons of sesame oil.
First, prepare the rice powder by mixing it with water until it becomes a smooth paste. Then, transfer the paste to a saucepan and cook it over medium heat, stirring constantly until it thickens. This process helps to remove the raw taste of the rice powder.
Next, combine the cooked rice paste with the red pepper flakes, fermented soybean paste, sugar, soy sauce, minced garlic, and sesame oil. Mix all the ingredients thoroughly until they are well combined. Adjust the amount of red pepper flakes according to your preference for spiciness.
Once everything is mixed together, transfer the mixture to a glass jar or container with a tight-fitting lid. Allow the sauce to ferment at room temperature for about a week. This fermentation process enhances the flavor and adds complexity to the sauce.
After a week, your homemade Gochujang sauce is ready to use. You can store it in the refrigerator for up to six months. This versatile sauce can be used as a marinade for meats, a dipping sauce for vegetables, or as a condiment for various dishes like bibimbap or Korean barbecue.

No, it is not recommended to eat gochujang raw as it may contain bacteria that can cause food poisoning. Gochujang should be cooked before being consumed to ensure food safety. Additionally, cooking helps release the full flavor and aroma of the paste, making for a more delicious dish.
Can you add water to gochujang?
Yes, you can add water to gochujang to thin out the paste and adjust the flavor. This is often done when making dishes such as bibimbap or Korean soups. Adding a small amount of water at a time helps prevent over-thinning, so it’s best to start with just a few drops and adjust according to taste. Adding too much water can lead to a loss of flavor, so be sure to add sparingly and taste as you go.
What is the fungus in gochujang?
Gochujang contains a type of fungus called Aspergillus oryzae, which is responsible for its distinctive flavor and aroma. This fungus is also commonly used in the production of other fermented sauces such as soy sauce and miso. It helps to encourage the growth of beneficial bacteria that break down complex molecules into simpler compounds, resulting in the unique sweet-sour-spicy flavors of gochujang.
Does gochujang have a lot of sugar?
No, gochujang does not usually contain a large amount of sugar. It is mainly composed of fermented soybeans, red chili peppers, glutinous rice flour and salt with an added sweetener such as honey or corn syrup to balance out the flavors. The sugar content in gochujang varies from product to product so it’s best to check the nutrition facts and ingredients list before purchasing.
Can you substitute gochujang with sriracha?
Yes, sriracha can be used as a substitute for gochujang in many recipes. However, it is important to note that these two sauces have very different flavors and textures. Gochujang has a thicker, stickier texture than sriracha and its flavor is sweet, spicy and savory. Sriracha, on the other hand, has a thinner consistency and is more commonly known for its heat rather than its sweetness. Therefore, it may be necessary to adjust other seasonings or ingredients in order to achieve the desired flavor when using a substitute.
How long does gochujang last after opeing?
Once opened, gochujang, a traditional Korean chili paste, should be consumed within 4-6 months when stored in the refrigerator. This ensures its optimal flavor and quality, allowing you to enjoy its rich and spicy taste in various culinary creations for an extended period of time.
