Old English win "wine," from Proto-Germanic *winam (source also of Old Saxon, Old Frisian, Old High German win, Old Norse vin, Dutch wijn, German Wein), an early borrowing from Latin vinum "wine," from PIE *woin-o-, related to words for "wine" in Greek (oinos), Armenian, Hittite, and non-Indo-European Georgian and West Semitic (Arabic wain, Hebrew yayin), probably from a lost Mediterranean language word *win-/*woin- "wine."
Also from Latin vinum are Old Church Slavonic vino, Polish wino, Russian vino, Lithuanian vynas, Welsh gwin, Old Irish fin, Gaelic fion. Essentially the same word as vine (q.v.). Wine snob is recorded from 1951. Wine cellar is from late 14c. Wine-cooler is 1815 as "vessel in which bottled wine is kept cool;" by 1977 as a type of wine-based beverage.
