Summary
Miso is a traditional Japanese fermented soybean paste widely used in various dishes, particularly in soups and sauces like Miso Shiro and Miso Ramen. It comes in several types based on ingredients and fermentation duration, including Mamemiso, Kome Miso, and Mugimiso, each offering different flavors from mild to intense. Miso is known for its health benefits, containing proteins, vitamins, enzymes, and more, although pasteurization during processing can reduce its nutritional value. Engaging in a Miso-making course provides a unique opportunity to learn the labor-intensive process of crafting this flavorful paste, which requires patience as it takes several months to ferment and develop its taste. Participants are provided with all necessary ingredients and equipment, making it an accessible and enriching culinary experience.The fermented paste is used in many Japanese dishes. You can find it in soups, sauces or as a dip. Miso is especially versatile in soups. For example, there is Miso Shiro or the well-known noodle soup Ramen. Miso-Ramen broth is made from the soybean paste. But there are also many other types of ramen that use miso. The paste is also suitable as a dip. Miso has a high salt content for preservation. Therefore, only a small amount of the salty paste is usually used when cooking Miso Shiro, or miso soup.
The variations of Miso Paste
Miso is divided into different categories depending on the ingredients, color and taste. Soybeans are always the basis. With Mamemiso (=bean miso豆味噌), this ingredient is used exclusively. With (=rice miso米味噌) rice is added and with Mugimiso (=grain/barley miso麦味噌) barley is added. There are also differences in color. This depends mainly on the fermentation time. You can store miso for several years and even decades. The only important thing is that the paste is airtight. However, one thing to keep in mind about the storage duration is that the intensity of the taste increases over the years.
At the very beginning, the paste is white and is also called Shiro-Miso (白味噌). You can still taste the soybeans, so it is rather neutral. The red miso is called Aka-Miso (赤味噌) and is in the middle of fermentation. The black Kuro-Miso paste (黒味噌) has the longest fermentation time. So it can be said that Kuro-Miso paste tastes the most intense of all three varieties. There are other flavors, namely spicy (Kara-Miso 辛味噌), sweet (Ama-Miso 甘味噌) and a mixture of different (Awase-Miso 合わせ味噌)
How healthy is Miso?
Basically, miso, like all fermented foods, is very healthy. The paste contains vitamins and nutrients such as: proteins, vitamin B2, vitamin E, various enzymes, isoflavones, choline and lecithin. However, this only applies to fresh miso. Since the taste constantly changes, the fresh variant is not suitable for sale in supermarkets. To prevent this, miso is usually pasteurized. After that, the miso paste no longer ferments and retains the same taste. Pasteurization heats the product so strongly that many nutrients are lost. Therefore, you should opt for the fresh variant. If you can get it, it's not exactly cheap. It also has a short shelf life. You have to use it up quickly, otherwise there is a risk of mold after opening. Or you want to intentionally make the taste a bit more intense.
A Course - Making your own Miso
Cooking classes are very common in Japan. They are even offered as a nice alternative to the school day for school classes. It is worth doing a miso course. Because the production of the popular paste is unknown to most people. The course is affordable at around 25 euros and you don't need to bring anything with you, as all the ingredients and cooking utensils are provided.
But you need to know one thing in advance. The course is hard work and you can't taste the results of the cooking right away. You can only use your own miso paste after half a year or a whole year.
But now to the course. Soybeans are processed into a paste by hand. You then shape this into a small ball and layer it in a bucket. Koji is added. These are molds that enable fermentation. Their work is only interrupted when consumed or pasteurized. Then salt is added. It is an important ingredient for taste and shelf life. Finally, the bucket is closed.
Now you have to be patient. Because you have to wait at least six months before you can try your miso paste. Until then it is stored in an underground storage pit, where it is always cool.
After the course, there is a short tour of the miso factory. Miso is produced here for sale. You can see the pastes in different stages of ripening. If you want, you can buy different miso products. These are more intense and aromatic in taste than the supermarket goods.
My Opinion of the Course:
If you are interested in Japanese cuisine and have the opportunity to take such a miso course, then you should take part once. I would never have thought that so much work goes into such an ordinary product as miso. The most fun was learning about the different types and their classification. And the most important thing for us was to learn how to handle miso when cooking so that it tastes really good.

Schöner article. I make my own miso because I can't find a decent one nearby. That's a whole different experience, where you really get to know the product and its versatility. I would recommend it to anyone who loves Japanese cuisine and amazing flavors.
Hi Kilian, that sounds great, go ahead and post your successes on our Facebook page :) Best regards, Matthias
I came across your blog while searching for miso on Google – very inspiring :-) I just ordered your Korea book, I'm curious!
Hello Birgit, that is great and makes us very happy, we put a lot of effort into it :) Thank you very much for the support. Best regards, Ryusei from RyuKoch
Sehr detailed article. But what happens to the lactic acid bacteria in miso when it is, for example, cooked in a soup? I’m really interested in the lactic acid bacteria, but if they are destroyed by heating, one of miso’s promised benefits is no longer present.
Hallo Klaus,
First of all, thank you very much, we put a lot of effort into it.
The lactic acid bacteria are usually already gone. Just like with sauerkraut, miso is also pasteurized. That means it is heated strongly so that the fermentation does not continue. The advantage is that fermentation stops and the products all taste the same. Of course, the problem is that some vitamins and lactic acid bacteria are lost in the process.
Suppose you have miso that hasn’t been pasteurized, then you should definitely add the miso last when making Miso Shiru (miso soup). It’s very important that the soup has not been boiling for several minutes already. That's because this way, the soup is no longer hotter than 70 degrees and the lactic acid bacteria and vitamins remain relatively intact. I generally recommend this approach, as the flavors also stay better in the soup than if you were to boil miso.

I hope this could help you :)
