Is Soy Sauce Vegan?
Yes — traditional soy sauce is vegan. Standard soy sauce is brewed from four ingredients: water, soybeans, wheat, and salt. All are plant-based. The fermentation process uses bacteria and molds (Aspergillus species), which are fungi — also vegan. The issue arises with flavored or specialty soy sauces that add oyster extract, fish, or shrimp — these variants are not vegan.
Standard Soy Sauce Ingredients
Traditional soy sauce (shoyu) is made by fermenting soybeans and roasted wheat with a salt brine over months or years:
- Water — vegan
- Soybeans — vegan
- Wheat — vegan
- Salt — vegan
Non-Vegan Soy Sauce Variants
| Product | Non-Vegan Ingredient |
|---|---|
| Oyster sauce | Oyster extract |

Note: Oyster sauce and fish sauce are distinct products, not soy sauce.
