I had to check the Greek:
ἑκουσίως ἀφεῖναι τὴν ψυχὴν ἀκράτου πίνοντα τοῦ οἴνου.
Sure enough, it seems to be just wine unmixed with water. That's not fatal, last time I experimented myself... Just sayin'
I found a Healthline article, with the following excerpt:
QuoteIs there a lethal BAC?
Generally, once your blood alcohol concentration (BAC) is 0.40 percent or over, it’s dangerous territory. At this level, there’s a risk of coma or death.
