Choosing miso with a longer fermentation period will provide more nutrients and benefits from fermentation. Also, by choosing additive-free miso, you can avoid unnecessary additives.
Longer fermentation period miso has more nutrients as it ferments for one, two, or three years、、、、、、, but where you can buy it is limited.
It is not an exaggeration to say that in ordinary supermarkets, there are very few that have been issued for more than one year.

Adding miso last and avoiding boiling will minimize the loss of nutrients.
