Risk level: May contain gluten
Traditional soy sauce often has gluten risk because wheat is commonly used in the brewing process. Choose soy sauce labeled gluten-free, wheat-free tamari, or coconut aminos, and check related sauces such as teriyaki, hoisin, and oyster sauce separately.
Many traditional soy sauces are brewed with soybeans and wheat. That is why the checker defaults soy sauce to May contain gluten unless the label gives stronger gluten-free context.
Tamari is often used as a gluten-free soy sauce alternative when it is made without wheat. Coconut aminos are soy-free and commonly used as a different flavor profile, but both still need label review.
Teriyaki, hoisin, oyster sauce, ponzu, and bottled marinades can contain soy sauce or wheat. Paste those labels into the checker instead of assuming the sauce category is fine.
Usually no. Traditional soy sauce often includes wheat and should be treated as a gluten risk unless the label says gluten-free.
Some tamari is gluten-free or wheat-free, but not every bottle is. Check the exact product label.
Compare gluten-free soy sauce, wheat-free tamari, and coconut aminos based on ingredients, sodium, flavor, and allergen statements.
