This is a barrel-aged tamari shoyu from soy sauce brewer Yamakawa, a soy sauce manufacturer local to Gifu prefecture. This tamari differs from other kinds of soy sauce because it is free of any wheat, making it gluten free.
Many varieties of tamari contain trace amounts of gluten, meaning that they are not suitable for those with gluten intolerance or allergies. In the case of this tamari shoyu from Yamakawa, they use a special method called “tosui-shikomi,” in which soybeans and koji are mixed with 100% clear stream water.
The water used in this tamari shoyu comes from the Nagara river in Gifu, which is famous for its delicious and fresh taste.
Only carefully selected raw materials of domestic soybeans, salt, and koji have been chosen to be included in this product, to ensure the best taste possible. The brewing water that determines the taste of soy sauce is underground water from the clear Nagara River, and the soybeans are whole soybeans from Gifu Prefecture.
This particular tamari shoyu has a richer and deeper flavor than traditional dark soy sauce, making it ideal to use as a dipping sauce for sashimi or cold tofu. It also tastes delicious on grilled meat, fish, and vegetables.
