What Is Miso?

Miso paste is a traditional Japanese seasoning made from fermented soybeans, along with additional ingredients like rice or barley.

If you've ever wondered how miso soup gets its salty, savory flavor, the answer is miso paste! You can use this secret ingredient to deepen the flavors in soup recipes, marinades, or even complement the sweetness in chocolate chip cookies.

What Does Miso Taste Like?

Savory is usually the word used to describe the flavor of miso. Different types of miso paste vary in intensity, but in general, you can compare the flavor of miso paste to a rich soy sauce. It's salty and concentrated with fermented hints of tanginess. Even though miso paste has a similar texture to peanut butter, it doesn't taste like peanuts, which can be a common misconception.

When using miso paste in your recipes, it's important to keep in mind that a little goes a long way. Due to its concentrated flavor, a small amount can greatly enhance the taste of your dish. It's best to start with a small quantity and gradually add more to achieve the desired flavor profile. We'll dive deeper into the flavors of different miso varieties below.

Types of Miso

The color of miso and its flavor profile go hand in hand. Typically, the lighter the miso, the more delicate and subtle its flavor profile becomes. As we move towards the darker end of the spectrum, the miso paste gains a more robust and pronounced taste. Just like with other fermented foods like kimchi or kombucha, a longer fermentation period increases the flavor intensity.

1. White Miso (Shiro)

Shiro miso, also known as white miso, is a type of miso paste made from fermented soybeans and rice or barley. Unlike its red counterpart, shiro miso is fermented for a shorter period, resulting in a milder and sweeter flavor profile. The color of shiro miso can range from pale yellow to light beige, making it visually distinct from the darker red miso.

This type of miso has a delicate and slightly sweet flavor with subtle hints of umami. Its mildness makes it a versatile ingredient that can be used in a wide range of dishes without overpowering other flavors. When compared to red miso, shiro miso is noticeably less salty, making it a great option for those who prefer a more balanced and nuanced taste.

2. Yellow Miso (Shinshu)

Yellow miso, or shinshu miso, is fermented for a longer time than white miso and has a larger percentage of soybeans and barley in the mixture. The flavor of yellow miso is considered saltier and more acidic than white miso and works well as a multipurpose flavoring or condiment.

Even though it’s called yellow miso, this type of miso can range from pale yellow to light brown. Yellow miso is often used in soups, dressings, marinades, and glazes. Its subtle flavor adds depth and complexity to dishes without overpowering other ingredients. It pairs well with seafood, poultry, and vegetables, making it a popular choice for miso-based sauces and glazes for grilled or roasted meats.

3. Red Miso (Aka)

Red aka miso is a type of fermented soybean paste that is darker in color with a stronger, more robust flavor compared to white miso. It's made through a longer fermentation process, which gives it a deeper and more complex taste. Its texture is thick and slightly grainy, making it perfect for adding texture to dishes.

Unlike white miso, which is made with a higher proportion of rice and has a milder, slightly sweet flavor, red miso is made with a higher proportion of soybeans. In terms of appearance, red miso has a deep reddish-brown color, which can range from dark amber to almost black. Due to its bold flavor, red miso is often used in heartier dishes such as stews, braises, and glazes. It pairs well with ingredients like root vegetables, mushrooms, and meats.

4. Mixed Miso (Awase)

Awase miso, or mixed miso, is a blend of different types of miso paste. Typically, it combines white (shiro) miso and red (aka) miso, creating a balanced flavor profile. The combination of these two miso pastes results in a complex, rich, and savory taste that's loved by many.

Awase miso strikes a perfect balance between the sweetness of white miso and the robustness of red miso. It has a slightly salty and tangy flavor with subtle hints of sweetness. The depth of flavor in awase miso makes it a versatile ingredient that can be used in a wide range of dishes.

5. Hatcho Miso

Hatcho miso is a traditional type of miso that originated in the Aichi Prefecture of Japan. What sets it apart from other types of miso is its unique production process. Unlike other varieties, hatcho miso is made solely from soybeans, without the addition of any grains. This gives it a distinct flavor and texture that is loved by miso enthusiasts.

This dark, rich, and robust miso has a deep umami flavor with hints of sweetness. Its flavor profile is more intense compared to other types of miso, making it a popular choice for those who prefer bolder flavors. The fermentation process of hatcho miso can take up to three years, resulting in a complex and deeply satisfying taste.

6. Mugi Miso (Barley)

Mugi miso, also known as barley miso, is made from a combination of soybeans and barley. Unlike other types of miso that are primarily made from soybeans, mugi miso has a distinct flavor profile that sets it apart. The addition of barley gives it a slightly sweet and nutty taste, making it a popular choice for those who prefer a milder miso flavor.

Mugi miso is also known for its lighter color compared to other types of miso. It typically has a golden hue, which adds a visually appealing element to dishes. This lighter color can also impact the taste, as mugi miso tends to be less salty compared to darker miso varieties.

7. Genmai Miso

Genmai miso, also known as brown rice miso, is made from a combination of soybeans and whole-grain brown rice. This type of miso is fermented for a longer period compared to other varieties, resulting in a rich, complex flavor. The combination of soybeans and brown rice gives genmai miso a nutty and slightly sweet taste, making it a popular choice for soups, stews, and marinades.

What sets genmai miso apart from other types of miso is its distinct color and texture. While most miso varieties have a smooth and creamy texture, genmai miso has a slightly grainy texture due to the presence of whole-grain rice. This texture adds an interesting element to dishes, making them more satisfying and hearty.


How Is Miso Made?

Miso production begins with koji, a fungus used for making many popular fermented foods in Japan. The scientific name for koji is Aspergillus oryzae, and it’s used to develop complex flavors in foods the same way bacteria and mold are used to create flavors in cheese. To make koji, spores are added to a starter material of steamed rice or a mixture of rice and soybeans.

As the koji incubates, it turns starches into sugar and releases glutamate to create umami flavor. Miso is made by adding koji to soybeans, rice, or barley and allowing the mixture to ferment even further to produce flavors of varying intensity. Depending on the ratio of rice and barley and the length of fermentation, different flavor profiles can be created.

Nutritional Benefits of Miso

Miso is considered a superfood with a variety of health benefits. Just like other fermented or cultured foods, the probiotics in miso help to support a healthy digestive system. In addition to containing all the amino acids needed to make a complete protein source, miso contains manganese, copper, and zinc. It’s also a source of omega-3 fatty acids, B vitamins, and vitamin K. This nutritious paste has a high sodium content, so it should be used in moderation. Thanks to its rich flavor, a little goes a long way. In order to preserve the probiotics in miso paste, add it to your finished recipes so that the microorganisms are not destroyed by high heat. Also look for unpasteurized miso to get the most health benefits.


Now that you are more familiar with this secret ingredient, you can try incorporating it into your menu. Its strong umami flavor complements a variety of foods. You can add it to mashed potatoes, corn on the cob, or even use it to add saltiness to cookies or ice cream. Miso paste has a unique, savory flavor that will add something special to your recipes.
