A rich, complex umami flavor is what we crave in soy sauce. Traditional brewing methods, reminiscent of winemaking, allow Kikkoman soy sauce to age and develop these deep, robust notes. This natural process begins with a mash of soybeans, wheat, water, and koji (Aspergillus oryzae mold), which is then matured in wooden barrels or vats.

Naturally brewed Kikkoman soy sauce, like the orginal Naturally Brewed variety, continues to ferment and age in barrels for up to three years. During this time, the microorganisms in the mash continue to break down proteins and carbohydrates, creating a rich, complex flavor profile that deepens with age.

As naturally-brewed Kikkoman soy sauce ages, it develops a more robust umami taste, complemented by hints of sweetness and smooth, rounded finish. Its color shifts from the familiar clear, golden hue towards a darker, reddish-amber. These changes are due to the gradual breakdown of proteins and the Maillard reaction, which is responsible for the characteristic aromas and flavors in aged foods.

For chefs and food enthusiasts, this evolution brings exciting new dimensions to their dishes. A dash of aged Kikkoman can add depth and richness to marinades, glazes, or as a final touch to ready-plated dishes.

Pasteurized Kikkoman soy sauce, like the Classic variety, undergoes an initial 60-day fermentation and then is heated to kill any remaining microorganisms. While this stops the aging process, it helps maintain a consistent, balanced flavor across batches. The heating process enhances solubility, enhancing the sauce's versatility in various dishes and cooking methods.

Pasteurized soy sauce offers a lively, well-rounded umami flavor that's familiar to many palates. It's an excellent everyday option for home cooks, offering reliability and convenience without sacrificing too much in the way of depth or complexity.
