Taroemon Ueda was a Hosokawa clan vassal experienced in western customs and the historical document says he used “black soybeans and wild grapes” to make wine. Earlier documents revealed that Taroemon took about 10 days to finish making wine, and with this, the researchers calculated that the batch ordered by Tadatoshi Hosokawa was probably finished by mid-October 1632 AD, at the latest.
From The Arrival Of The Portuguese To The End Of Wine
Tadatoshi finished his last batch of wine in October 1632 AD. And on January 18th of the following year the shogunate ordered the Hosokawa clan to move from the traditional wine making Kokura domain to the Higo domain. Previous researchers suspected wine production was halted in Japan because it was “a stereotypically Christian drink and making it could have been a dangerous prospect due to the shogunate s strict prohibition of Christianity during the Edo period,” according to the press release on Eurekalert.
