Teraoka Shoyu was founded in 1928 in the soy sauce heartland of Choshi, Japan, by a family dedicated to a single craft. They created this Organic Dark Soy Sauce for the modern cook who wants authentic, deep umami without compromise. The formula uses only three ingredients: Japanese-grown organic soybeans, organic wheat, and deep-sea salt, fermented for over 6 months in 100-year-old cedar barrels. This traditional 'koikuchi' method is certified organic by JAS (Japanese Agricultural Standard) and is a designated 'Jyozu' (excellent brewing) product by the Japanese government. It's the top-selling organic soy sauce in its category across specialty Japanese markets, chosen by home chefs and professional kitchens for its reliable, complex flavor that elevates any dish from simple to exceptional.

Teraoka Organic Dark Soy Sauce 500ml is crafted by Teraoka Organic Brewing using a traditional Japanese koikuchi method, which involves a meticulous fermentation process. The primary ingredients include organic soybeans, organic wheat, salt, and water. Organic soybeans serve as the foundational protein source, undergoing fermentation with koji mold (Aspergillus oryzae) to break down proteins into amino acids like glutamic acid, which is responsible for the rich umami flavor characteristic of this sauce. Organic wheat is added to provide carbohydrates that feed the fermentation process, contributing to the development of complex flavors and a balanced sweetness. Salt acts as a natural preservative, inhibiting unwanted microbial growth while enhancing the savory profile and extending shelf life. Water is used to adjust consistency and facilitate fermentation. This combination results in a dark, full-bodied soy sauce with deep umami notes, offering benefits such as enhanced flavor depth in dishes, a rich aroma, and a versatile culinary application for marinating, dipping, or seasoning, all while adhering to organic standards for a cleaner, more natural product.
