All the Miso Types: An Overview

In many cultures around the world, for thousands of years people have been fermenting meat and fish for the sake of preserving it. This led to the discovery of the umami flavor, which today is termed the fifth basic taste, and which directly resulted from fermentation. Through fermentation, proteins get broken down into their component amino acids, triggering the release of glutamic acid which imparts the famous umami flavor. This development also took hold in East Asia. Since the soybean has been cultivated since ancient times and also has a full amino acid profile just like meat, people in Aast Asia have taken advantage of this bean through fermentation for a very long time. Fermented soy paste has different forms and names in different countries in East Asia, e.g. Doujiang(豆酱) in China, Miso (味噌) in Japan and Doenjang (된장) in Korea. The flavours also vary between spicy, sweet, and savory across different regions in Asia. Yet, in each food culture, they are cherished as basic flavouring ingredients and are all produced with salt, soybeans, and bacteria or molds - the drivers of the fermentation process. 

Like soy sauce, Miso can come in a variety of colours and flavors. Another similarity to soy sauce is that fermentation time and ingredients determine the taste and color of the miso. To give an insight into how the different combination of ingredients with soy and the fermentation time creates a huge diversity of tastes, we will focus on the Japanese Miso Palette as an example. In Japan, Miso can be made of a combination of rice and soybeans, barley and soybeans, or only soybeans. 

Miso with Soy

This miso is made only from soybeans and fermented for almost three years. Hatcho Miso is named after the small village which it originated many hundred years ago. Hatcho miso counts as the most noble miso of all misos. Also, it used to be an essential food for supplying the military in Japan during the time when there were a lot of civil wars. As it is made only from soybeans, it develops a strong umami taste but has a less creamy consistency than most of the other miso types. Moreover, the long fermentation period unleashes an intense flavor. All in all, Hatcho miso can be said to have a full-bodied taste and a bitter, malty flavor that has a resemblance with the flavor of dark chocolate.

Miso with Rice and Soy

Shiro Miso (White Miso)

Shiro Miso is made of rice and soybeans and generally has the highest proportion of rice amongst all miso types. It also has the shortest fermentation time of all misos (3 months) which is where it gets its light colour from, hence the name Shiro, which means white in Japanese. Its short fermentation time and high rice content contributes to a rather mellow and sweet, and creamy flavor. Due to its subtle flavour, it is a good miso to get started with if one is not yet acquainted with the world of miso. Due to its mild and sometimes slightly nutty taste, it can even be used in place of dairy in some cases.

Shinshu Miso (Yellow Miso)

This miso has a rice content similar to Shiro miso but is fermented over a slightly longer period than white miso (about 6 months). It gets its name from having originated in the Shinshu region in Japan. Due to its longer fermentation time, it has a slightly saltier and stronger flavor, but can be used for similar purposes as Shiro Miso.

Aka Miso (Red/ Amber Miso)

Aka Miso usually consists of 70 % of soybeans and 30 % rice. It’s fermentation time can be as long as two years and its name is derived from its red/amber colour. It is more assertive in taste than white or yellow miso, and it is better suited for dishes for which a strong umami flavor is favorable.

Product Example: Ama Miso

Genmai Miso (Brown Rice Miso)

Whereas in most miso types made with rice and soybeans, peeled white rice is used, this type contains full grain, unpeeled rice. It is usually fermented over a long time, up until two years and is named after the Japanese word for brown rice. The brown rice contributes to a slightly bitter taste, and in combination with its fermentation time, causes it to acquire its dark brown colour. This miso is one of the Japanese classics.

Miso with Barley & Soy

Mugi Miso (barley Miso)

For Mugi miso, barley is used instead of rice. Mugi Miso has an exceptionally long fermentation time that can be as long as three years. Unsurprisingly, Mugi also translates into Barley from Japanese. It accounts for 11 % of total domestic production and is produced in the southern regions of Kyushu, Shikoku, and Chugoku in Japan. As barley contains less starch than rice, the resulting flavor is more intense and rather malty. It can be found in a variety of colours ranging from medium brown to dark brown.

Mixed Miso & more variations

While practically any miso can be mixed, this miso refers to a special mixture of white and red miso. As such, rice, barley, and soybeans are combined. This combination helps achieve a unique taste and the ratio of both ingredients can be altered to define the preferred taste. Moreover, the combination of the three ingredients makes it a very versatile miso. 

Aside from these miso types and the combinations of ingredients used for them, there are also various other variations. Miso can be made with millet, rye, buckwheat, poppyseeds, Quinoa, corn, and even chickpeas.

How to use the different miso types

When it comes to how to apply each miso, there are no definite uses for each misos. Yet, it can generally be said that lighter misos with more milder flavors work well in combination with lighter dishes in which the miso should not trump the flavor of the dish nor stain the color of a meal. Meanwhile, darker miso types with a more assertive taste can be applied when a stronger umami flavor in the dish is desired. Misos can also be combined which allows for an even broader scope in tastes. All in all, you can be very flexible when deciding what miso to apply.
