The Gozenshu Brewery is one of the few in Japan using bodaimoto, a 600-year-old fermentation method, to make sake. They use it to make junmai, or pure rice sake that has no added alcohol or sugar. But mass-produced sake made with cheap additives is threatening the business.
Kamebishi's 20-year-aged soy sauce is the most expensive soy sauce in the world, sometimes selling for $125 for less than 4 tablespoons. The soy sauce has been made using the same family recipe since 1753 and follows the traditional mushiro koji method, in which each step takes years to complete.
