Old English win, from Proto-Germanic *winam (cf. Old Saxon, Old Frisian, Old High German win, Old Norse vin, Dutch wijn, German Wein), an early borrowing from Latin vinum "wine," from PIE *win-o-, from an Italic noun related to words for "wine" in Greek (oinos), Armenian, Hittite, and non-Indo-European Georgian and West Semitic (cf. Arabic wain, Hebrew yayin), probably from a lost Mediterranean language word *win-/*woin- "wine." Also from Latin vinum are Old Church Slavonic vino, Lithuanian vynas, Welsh gwin, Old Irish fin. Essentially the same word as vine (q.v.). Wine snob is recorded from 1951.
