Step-by-Step Guide to Making Soy Sauce

Step 1: Prepare the Soybeans

Soak the soybeans in water for at least 12 hours. This allows them to swell and soften, making them easier to cook.

Step 2: Cook the Soybeans

Drain the soaked soybeans and place them in a large pot with fresh water. Cook them until they are soft, approximately 3 hours. Drain again and let them cool.

Step 3: Create Koji

Mix the cooked soybeans with wheat and sprinkle the koji starter over the mixture. Place it in a warm area (about 30°C or 86°F) for 3 days, allowing it to ferment.

Step 4: Combine with Saltwater

After the koji has developed, mix it with saltwater in your fermentation container. Use a ratio of 1 part koji to 1 part saltwater.

Step 5: Fermentation

Cover the container with cheesecloth and place it in a cool, dark area. Allow it to ferment for 6-12 months, stirring occasionally.

Step 6: Strain and Bottle

After fermentation, strain the mixture through cheesecloth to separate the liquid from the solids. Bottle the liquid soy sauce and seal tightly.

Understanding the Fermentation Process

Fermentation is crucial for developing the flavor of soy sauce. During this process, enzymes break down the proteins and starches in the soybeans and wheat into amino acids and sugars, creating the umami flavor characteristic of soy sauce. It's essential to maintain the right temperature and humidity during fermentation to ensure the best results.

How to Store Your Soy Sauce

Homemade soy sauce should be stored in a cool, dark place. For long-term storage, refrigeration is recommended. Properly stored, it can last for several years.
