1. For Miso Soup: Dissolve 1 tablespoon (approx. 18g) of paste per cup (240ml) of hot water or dashi. Do not boil after adding miso to preserve live enzymes and flavor. 2. As a Marinade: Use 2-3 tablespoons as a base for marinades for fish, poultry, or tofu. The enzymes help tenderize. 3. As a Flavor Booster: Add a teaspoon to stews, gravies, or salad dressings for an instant umami lift. Timeline Expectations: Week 1: Notice the deeper, more complex savory flavor compared to standard miso, with less harsh saltiness. Week 2-3: Your homemade soups and dishes develop a restaurant-quality broth depth that becomes your new standard. Week 4+: You instinctively reach for it to enhance a wider variety of dishes, appreciating the consistent, rich flavor that processed pastes can't match.

Adachi Shoten was founded in 1923 in a small Kyoto workshop, dedicated to preserving the art of slow fermentation that modern food production often rushes. Our master fermenters noticed that today's fast-paced lifestyle and processed foods make it hard to experience true, deep umami flavor at home. We created this Aged Koji Rice Miso Paste to solve that. We source only Japanese-grown, non-GMO soybeans and rice, and use a proprietary koji kin strain developed over three generations. Every batch is fermented for a full 24 months in traditional Japanese cedar kegs, a method certified by the Japan Miso Promotion Foundation. This commitment to authenticity has made it the top-ranked artisanal miso paste in its category for home cooks seeking restaurant-quality depth.

Adachi Aged Koji Rice Miso Paste is crafted from a traditional Japanese recipe that includes soybeans, rice koji (rice inoculated with Aspergillus oryzae mold), salt, and water. Soybeans serve as the primary protein source, providing a rich, savory base and essential amino acids that contribute to the paste's nutritional profile and umami depth. Rice koji is the key fermenting agent, breaking down the soybeans' starches and proteins into simpler sugars and amino acids through enzymatic action, which enhances flavor complexity and digestibility while imparting a subtle sweetness. Salt acts as a natural preservative, controlling fermentation by inhibiting unwanted bacteria and ensuring a stable, long-lasting product. Water facilitates the fermentation process, maintaining the proper consistency for aging. This combination results in a miso paste with a balanced umami flavor, probiotic benefits from live cultures, and antioxidants from fermentation, supporting gut health and offering a versatile, nutrient-dense ingredient for soups, marinades, and dressings.
