unopened pantry2-3 years from production date, or 6-12 months past 'best by' date for optimal quality
Signs of Spoilage
Extremely rare for safety issues due to high salt content and fermentation. Quality degradation might show as slight darkening or an intensified, less balanced flavor. Mold is virtually impossible in an unopened, sealed bottle.
How to Check
Check the 'best by' or 'best before' date on the bottle. Visually inspect the bottle for any signs of seal compromise, leakage, or external damage. As safety is rarely a concern, focus on quality.
Storage Tips
Store in a cool, dark place away from direct sunlight and significant temperature fluctuations. While safe indefinitely, the quality (flavor, aroma) will slowly degrade over time.

Signs of Spoilage
Hazy appearance, unusual cloudiness, presence of white film or mold (though rare), significant darkening beyond its original color. An off-odor such as sour, yeasty, metallic, or generally unpleasant smell. A sour, bitter, metallic, or 'off' taste, or a noticeable loss of its characteristic savory, umami flavor.
How to Check
-
Visual Inspection: Hold the bottle up to a light source and look for clarity. Any floating particles, unusual films, mold growth, or discoloration (beyond natural sediment which can occur) are red flags.
-
Smell Test: Pour a small amount into a clean spoon or cup. Inhale gently. It should smell savory, slightly salty, and pleasant. A sour, vinegary, or otherwise unpleasant odor indicates spoilage.
-
Taste Test (small amount): If visual and smell tests pass, dip a clean spoon into the soy sauce and taste a tiny drop. It should taste as expected—salty, savory, and umami. Any sourness, bitterness, or chemical/unpleasant taste means it's gone bad.
Storage Tips
Always ensure the cap or lid is tightly sealed immediately after each use to prevent oxidation and potential contamination. Store on an interior shelf of the refrigerator where temperatures are most consistent. Reduced sodium varieties may degrade slightly faster than regular soy sauce due to lower preservative (salt) content.
