Flavor profile

Soy sauce's flavor complexity comes from parallel processes: Aspergillus oryzae and A. sojae molds break down proteins to glutamates (umami) and starches to glucose; Lactobacillus bacteria produce lactic acid and complex flavor compounds; yeasts generate alcohols and esters; and long aging develops Maillard reaction products. Japanese shoyu (tamari without wheat; koikuchi the standard; usukuchi light-colored but more salty; white shiro shoyu very pale) differ from Chinese soy sauces (dark soy — aged, slightly sweet, thick; light soy — saltier, used for seasoning). The distinction between light and dark soy sauce is critical: dark soy for color and depth in braises and stir-fries; light soy for seasoning and dipping where a saltier, cleaner flavor is desired. In cooking, soy sauce is used as a salt replacement (with umami bonus), as a marinade component, in glazes (reduced with mirin and sake for teriyaki), in soups and braises, and as a dipping sauce. Maillard compounds in soy sauce (including furaneol and HDMF) contribute to the caramel, sweet-roasted notes.
