Editorial summary

This summary is editorial and is general information, not a religious ruling. The status above is unchanged.

What it is

Soy sauce, shoyu and tamari are made by fermenting soybeans, usually with wheat, salt and a mold, and they are used in cooking, marinades and as a table sauce. Naturally brewed soy sauce contains a small amount of alcohol produced in fermentation, which is not added as an ingredient.

Why scholars differ

One published ruling gives the typical alcohol content of most soy sauces as about 1.5 to 2 percent, and another quotes a major brand stating that its product contains more than 2 percent. Some scholars permit soy sauce because the alcohol is a natural by-product of fermentation, is not intoxicating in this form and is present in small amounts, and one answer sets a limit of less than three percent. Others take the more cautious view that it is best avoided, particularly now that alcohol-free soy sauces are widely available.

Reading a label

Look for halal-certified soy sauce or for products labeled alcohol-free, and read the ingredient list for added alcohol, which is separate from fermentation alcohol. Mirin and cooking wine, which are often used with soy sauce, are different, since one ruling describes mirin as an intoxicant. Most soy sauce also contains wheat, and the FDA notes that soy sauce made with wheat cannot carry a gluten-free claim, so a wheat-free tamari answers a different question from a halal one.

Practical tips

Many brands sell halal-certified or alcohol-free soy sauce, and tamari, which is often made with little or no wheat, has the same fermentation question. Coconut aminos and liquid aminos are soy-free or differently made alternatives, each with its own label to read. In restaurants, soy sauce is used in marinades and sauces without being named, so ask if you are unsure.

In short

In short, naturally brewed soy sauce contains a small amount of fermentation alcohol, and scholars differ on whether that is acceptable. Alcohol-free and halal-certified soy sauces are widely sold.

What to ask the manufacturer

Ask the manufacturer in writing where the ingredient comes from: whether it is plant, microbial or animal in origin, and if it is animal, which animal and how it was slaughtered. Ask whether any alcohol was used as a solvent or carrier, and whether the product carries a halal certificate from a body your local authority recognizes. Keep the answer, because suppliers and recipes change.
