Japanese Miso Types Explained: Rice, Barley, Soybean, White & Red Miso
Miso is one of those ingredients where “white vs red” is useful, but it is only half the story. The koji type matters too.
Miso can be classified by koji type, taste and color.
MAFF explains rice miso, barley miso and soybean miso as major categories, while color and salt/sweetness create additional styles.
Three big ingredient families
Japanese miso is commonly grouped into rice miso, barley miso and soybean miso according to the type of koji used. Rice miso then branches further into sweet, mild and salty styles with different colors.
The broadest family across Japan.
Common in Kyushu, Shikoku and parts of western Japan.
Dark, robust style associated with Aichi, Gifu and Mie.
“White” and “red” describe color/style, while rice, barley and soybean describe the koji/raw-material category. Use both clues together.
Why white miso is often sweeter
MAFF describes white sweet miso such as Saikyo miso as using a higher koji ratio and lower salt concentration, with relatively short maturation compared with many darker styles.
Why red miso can be very different by region
Some red miso is rice miso aged longer; soybean miso is another dark family with a distinctive, robust umami profile. “Red” is therefore not one single recipe.
White sweet miso
Mild, sweeter style; Saikyo miso is a famous example.
Salty rice miso
Includes styles such as Shinshu and Sendai miso.
Soybean miso
Deep red-brown, strong umami; includes regional names such as Hatcho-style miso.
If you're buying your first tub, I would choose based on the dish you actually cook. Miso soup, marinades and sweeter sauces do not always want the same miso.

Bottom line
Read miso in two layers: what koji family is it? and what color/taste style is it? That is much more useful than simply asking which miso is “best.”
