Excellent Japanese ambient track name on my player just now..."Fantasy In Soy Sauce"

Recently been down a rabbit's hole learning about how deep the waters are re: #SoySauce in #Taiwan and it's been fascinating.

Terminology! Soy sauce made with black beans (apparently the traditional method going back to way back when) is called something different than the stuff made from soybeans and what.
I'd tell y'all which is which but I haven't sorted it out yet myself.

Methods! Some companies buy "bean juice" and then process. Some go from bean to sauce. This matters for pricing.
