In vino veritas translates as "In wine there is truth" - i.e., you say things you might not ordinarily say after you have had too much to drink. Not necessarily clever things, just truthful things.
English phrasing does not always translate straight across into Latin all that well, so here is a variation:
Vinum tibi astum efficit. (to one person)
Vinum vobis astum efficit. (to multiple people)
Literally, "Wine brings about cleverness to you."
astus -us m. [cleverness, cunning]
efficio -ficere -feci -fectum [to do, produce, effect, make]; of results, [to bring about, cause]
tibi is a singular "to you"
vobis is a plural "to you"
