There are four basic kinds of Korean soy sauce: Yangjo Ganjang, Hansik Ganjang, Sanbunhae Ganjang, and Jin Ganjang.
– Yangjio Ganjang is a soybean- and rice-, barley-, or wheat-based soy sauce that takes at least 6 months to ferment. It’s the least salty and the most expensive of the four soy sauces.
