"After you drink it"

it bites like a serpent ... it stings like an viper

The word "it" refers to "the wine when it is red." "Bites" and "stings" are metaphors for the way too much wine makes people feel. Alternate translation: "it makes you feel as bad as if a serpent had bitten you or an viper had stung you" (See: rc://en/ta/man/jit/figs-metaphor and rc://en/ta/man/jit/figs-simile)
