Soy Sauce is a savory condiment made from fermented soybeans, wheat, salt, and water, known for its umami-rich, salty flavor. In the context of alcohol and cocktails, soy sauce is used to add a savory depth and complexity, particularly in savory and experimental drinks. It pairs well with spirits like vodka and whiskey and can be used in cocktails such as a soy sauce-infused Bloody Mary or a savory soy sauce Old Fashioned. The addition of soy sauce can create a unique, umami flavor profile, enhancing the richness and depth of a cocktail.
