Is Soy Sauce (Naturally Brewed) Halal?

Detailed Explanation

What is it? A liquid condiment of Chinese origin, traditionally made from a fermented paste of soybeans, roasted grain, brine, and Aspergillus oryzae molds.

Why it may be doubtful Naturally brewed soy sauce (like Kikkoman) undergoes fermentation, producing about 1.5% to 2% alcohol naturally. This is not added alcohol, but a byproduct of brewing. Non-brewed (chemical) soy sauce does not have this.

Fiqh considerations There is a difference of opinion. Many scholars say that because this alcohol is a natural byproduct, is not added to intoxicate, and the sauce cannot intoxicate even if consumed in large quantities, it is permissible. Others prefer absolute strictness and advise using "Tamari" or "All-Purpose" soy sauces that explicitly have no alcohol.

Practical advice If you follow the majority opinion on natural trace alcohol, it is fine. If you want to be completely safe, buy Halal-certified soy sauce or look for Kikkoman's specific Halal/Gluten-Free variants.
