I guess this shouldn’t come as a surprise:
On Korea’s Chosun TV, the clip was dubbed “derogatory.” Korean site Dailian said the clip lacked proper fact checking. Other Korean sites also criticized the “poo wine” video.P
The drink is called “ttongsul” (똥술). In the video, Vice Japan’s Yuka Uchida (above) travels to South Korea and acknowledges that “it was hard to find reliable information online” about the drink. However, Uchida says a traditional Korean medicine practitioner named Dr. Lee Chang Soo is “one of the last people” to know how to make the drink. She also interviews young Koreans about ttongsul, and they appear to have no clue what she’s talking about.P
Okay, to recap: Not much reliable info about ttongsul (there doesn’t even appear to be a Korean wiki page!), one guy claims to be one of the last who can make it, and young Korean people have never heard of it. Sounds… thin.
For what it’s worth, the Weekly Kyunghyang did mention ttongsul very briefly in a 2003 cover story on rare alcoholic beverages—to be more specific, they said it was very rare, it was used to cure contusions, and it was made by putting poo from a healthy child in makgeolli over night. And the passage was written largely in the “It is said…” format, which suggests that writer himself isn’t even sure it exists. Enha Wiki also has a passage on it, noting that in the old days, some pansori singers would take it when they lost their voice. How reliable the page is, though, I couldn’t tell you.
What I didn’t know is that the whole “Koreans drink poo wine” has been something of a meme in certain quarters of Japanese cyberspace. I guess it’s one of those things Japanese right-wingers get off on, in addition to their usual diet of tentacle rape porn.
