Red miso (aka miso) — long-aged Japanese soybean paste, deep reddish-brown, intensely salty-umami. Strongly-flavored miso for winter soups, glazes.
Across cuisines
Aka miso (赤味噌) is the backbone of Nagoya's miso culture: Miso Katsu (dark hatcho miso sauce over pork cutlet), hitsumabushi variant dipping bowls, and Awase Miso blends combine aka with shiro for layered depth. Hatcho miso — the extreme variant — ferments 2–3 years under stone weights in cedar barrels, producing nearly black paste with intense astringency balanced by amino acid richness.
Notable varieties
Fermented 2–3 years under stone weights. Very low moisture, near-black color, intense savory astringency with minimal sweetness. PGI-protected; produced only in two producers in Okazaki city.
Medium-red barley-rice blend, 12-month ferment. Saltier and more robust than Kansai aka miso, with a grainy texture. Used in Tohoku hot pots and hearty miso soups.
