Red Miso and Awase Miso (赤味噌・合わせ味噌)
Red miso is the long-aged, darker class; awase is a blend of misos - the all-purpose middle most beginners should start with.
| Red miso (aka miso) | Longer maturation and a higher soybean share give a dark red-brown colour and a strong, salty-savoury taste |
|---|---|
| Awase miso | A blend - most often rice miso with soybean miso, or red with white - balanced for everyday use |
| Which to buy first | Awase, if only one tub: it is made to sit between white and red in strength |
Red miso's depth comes from time: months to years of maturation darken the paste through the same browning reactions that colour soy sauce. Sendai and Tsugaru misos are red rice misos; Hatcho is a red soybean miso.
Awase simply means 'combined'. Makers blend to hit a target flavour - for example softening a strong red with a sweet white - and many of Japan's best-selling household misos are awase. On an export label, 'awase' or 'blended' signals this middle style, and it is the safest single purchase for miso soup and general cooking.
