Ready to eat!

Look at the beautiful white color of miso soup bowl.

Shinshu koji miso tastes FANTASTIC!! It’s sweet but not too rich. Although the feature of this miso is the sweetness, but you can still feel saltiness at the same time.
If you imagine about the sweetness of sugar or honey, it’s not like that.
I think “mild” is the best word for Shinshu koji miso.

You should definitely try this traditional sweet miso soup!

Enjoy your miso soup!
