Ishimago Shoyu was founded in 1912 in Kanazawa, Japan, a region famed for its pristine water and artisanal food culture. For over a century, they have focused on one principle: reviving the deep, complex flavors lost in modern, mass-produced soy sauces. This 2-Year Aged Saishikomi Shoyu was created to solve the problem of bland, one-dimensional cooking. The formula uses a traditional 'saishikomi' (re-fermentation) method, where a new batch of soy and wheat koji is fermented not in brine, but in a 2-year-aged soy sauce from their own cellar. This double fermentation, guided by a Toji (master brewer) and certified under Japan's JAS (Japanese Agricultural Standard) for traditionally brewed soy sauce, extracts over double the amino acids and umami compounds. It has become a top-ranked premium soy sauce in Japanese culinary magazines for its ability to transform even simple dishes.

Ishimago Saishikomi Shoyu 300ml is a premium double-fermented soy sauce crafted through a traditional Japanese brewing process. Its ingredients include soybeans, wheat, salt, and water, which undergo a meticulous two-year aging period. Soybeans provide the essential proteins that break down into amino acids during fermentation, contributing to the sauce's rich umami flavor and savory depth. Wheat is added to supply carbohydrates that convert into natural sugars, balancing the saltiness and enhancing the sauce's subtle sweetness and aroma. Salt acts as a natural preservative, controlling the fermentation rate and ensuring food safety while intensifying the overall flavor profile. Water serves as the medium for fermentation, facilitating the enzymatic reactions that develop the sauce's complex characteristics. This double-fermentation method, where the sauce is re-fermented with previously brewed soy sauce (koikuchi shoyu), results in a denser, more concentrated product with a deeper color and a smoother, less harsh taste compared to single-fermented varieties. The benefits to users include a versatile condiment that elevates dishes with its robust umami, enhances marinades and dressings without overpowering other ingredients, and offers a naturally brewed alternative to artificially flavored sauces, aligning with clean-label preferences. The extended aging process ensures a well-rounded flavor that complements both traditional Japanese cuisine and modern culinary applications.
