What Is Japanese Soy Sauce And How Is It Different From Other Kinds?

Japanese soy sauce, known as “shoyu,” is a fermented liquid condiment made from soybeans, wheat, water, and salt. It is an integral part of Japanese cuisine, adding a distinctive umami flavor to dishes ranging from sushi and sashimi to soups, marinades, and dipping sauces.

The History of Soy Sauce

The origins of soy sauce can be traced back to ancient China, where it was first produced around the 2nd century BCE. It was introduced to Japan during the Nara period (710-794 CE) and quickly became a staple ingredient in Japanese cooking.

How is Soy Sauce Made?

The traditional process of making soy sauce involves several steps:

1. Soaking: Soybeans and wheat are soaked in water for 12-24 hours.
2. Cooking: The soaked beans and wheat are steamed or boiled.
3. Koji-Making: A mold called Aspergillus oryzae is added to the cooked beans and wheat, which initiates the fermentation process.
4. Fermentation: The mixture is allowed to ferment in large vats for several months, during which enzymes break down the proteins and carbohydrates into amino acids and sugars.
5. Pressing: The fermented mixture is pressed to separate the soy sauce from the solids.
6. Aging: The soy sauce is aged in wooden barrels for a period of months or even years, which mellows the flavor and develops complexity.
