What is Miso?

Understanding Miso is like understanding wine, no two Cabernets or Shiraz taste the same. It is the same with Miso, one white Miso from one Miso Maker will taste different to a white Miso from any other Miso Maker. And just like wine, there are some Miso that are mass produced with an anomalous flavour profile while others are crafted by artisan makers in small batches to the highest standards.

Miso is a traditional Japanese seasoning made from koji (inoculated rice, barley or soybeans), soybeans and salt. There are lots of different types of Miso and some of the names can be confusing, we’ve put together a quick guide to Miso below to help you get started.

Yellow Miso

A medium bodied Miso, not as sweet as white miso, aged for at least six months and is used as a general purpose Miso.

Use Meru Chickpea Miso in recipes that call for yellow Miso.


White Miso

A light bodied Miso that can range in colour from white to beige through to yellow. The light colour comes from a high proportion of Koji used in the recipe. White Miso, particularly Shiro and Saikyo Miso was traditionally reserved for royalty due the high proportion of Koji. Saikyo is generally the sweetest white Miso, followed by Shiro and then the rest have varying degrees of sweetness.

Use Meru Sweet White Miso in any recipe that calls for White Miso.

Hatcho Miso

This Miso is aged for up to three years to develop the full flavour. This Miso, in it’s truest form, is only made in two locations in Japan and they are known for the presence of particular microbes that give this Miso it’s unique flavour. 

Use Meru Chickpea Miso in place of Hatcho Miso and add a teaspoon of soy sauce for every tablespoon of Miso, to develop the flavours.
