Whether you‘re trying it for health reasons or just want to explore a new taste, tamari sauce is a great substitute for regular soy sauce. Tamari sauce is famous for its umami taste. Some even say that tamari sauce is a healthier choice for people who cannot eat gluten.
So, what exactly is tamari sauce?
What Is Tamari Sauce?
Tamari sauce or tamari soy sauce is a wheat-free Japanese variety of soy sauce. It is a fairly well known condiment so you can probably find it in the Asian condiment aisle in grocery stores near you.
In order to be massively produced, regular soy sauce is brewed with 50% wheat as an additional ingredient. As we know, wheat contains gluten, a protein that may trigger health problems to those who are intolerant.
Tamari sauce can be a great alternative to regular soy sauce since both have a slight similarity in terms of taste. In fact, due to its characteristic, tamari sauce has become a favorite soy condiment especially for those who want to eat gluten free. There are also certified gluten free tamari sauce in the market for people who cannot eat gluten at all.

Because tamari sauce is usually 100% soy based, it has a richer flavor profile. Although some brands may use wheat for their tamari production, the amount of wheat used is extremely small compared to regular soy sauce. Wheat usage in tamari sauce production is also done very rarely.
Originally, Tamari sauce was a byproduct of miso production. Tamari sauce is the liquid that accumulates during the fermentation process of soy when turning it into miso. The word 溜り tamari means collection, pool of water, or liquid runoff. In the miso industry, tamari means the liquid runoff from miso preparation.
Tamari sauce is great as a dipping sauce for sashimi and sushi. It can also be used for seasoning many dishes like teriyaki or used as a salad vinaigrette. When heat is applied to tamari sauce, the sauce will have a reddish hue, making it look good glazed on Japanese rice crackers.

In Japan, some households in Kyushuu and Tokai region uses tamari sauce instead of regular soy sauce for everyday cooking.

Tamari Sauce Brewing Process
Soaking and Steaming
Soybeans are washed and soaked for 2 hours and then steamed until soft
Koji making
Koji is a fermentation product made from a mold called aspergillus oryzae. It is used in many traditional Japanese food.
After the soybeans are steamed, they are minced into paste with machines and shaped into balls called misodama. After that, the misodama is sprinkled with koji starter to propagate koji. This propagation process is done for 3 days. After propagation is done, koji will be seen on the surface of the misodama.
Shikomi
In Japanese, shikomi means preparation. During this step, misodama that already has propagated koji is moved into a big wooden vessel. This vessel is closed with stones. The stones have to be neatly arranged, almost like a puzzle, so the weight is equal on all sides and all surface is covered. This job needs to be done by an experienced worker.
After the stones are arranged, salted water is added to the mixture through the stones. The amount of salted water can vary from half the scale of the soy mixture, to one full scale.
Aging (Maturation)
The maturing process of the mixture can take 2 to 3 years. After that, an umami liquid runoff will accumulates. This liquid runoff which is the tamari sauce can be collected. Some factories also pressed their mixture paste (moromi) in order to extract the tamari sauce.
Bottling
After extraction, tamari sauce is ready to be bottled and distributed.
