Best Method recommended method with best effort-to-efficacy tradeoff 1-2 years
Refrigerated (Opened)
- Keep the cap tightly closed limits oxidation that dulls flavor
- Store in the refrigerator after opening not required for safety, but keeps flavor at its peak
- Refrigerate low-sodium, small-batch, or unpasteurized types for best results less salt or live fermentation means quicker flavor changes
- Use within about a month for the freshest taste still perfectly usable well beyond this, just less vibrant
Alternative another good method that's just different 2-3 years
Pantry (Opened or Unopened)
- Store unopened bottles in a cool, dark cupboard
- Keep away from heat and direct sunlight heat and light accelerate flavor loss
- Keep the cap tightly sealed between uses
- An opened bottle stays safe at room temperature for months flavor slowly fades faster than in the fridge
Fun Facts
- Soy sauce is one of the world's oldest condiments, with roots in fermented pastes made in China more than 2,000 years ago.
- Its deep savory taste comes largely from glutamates created during fermentation, the same compounds behind the umami "fifth taste."
