Emirates lounges have a wine issue.
I was in A and B lounges over the weekend and tried various bottles of red wine that were out (Smith Haut Lafitte, Close de Tart, Lynch Bages, Pichon L etc). I know my wines and know what these wines are meant to taste like. All of them, with the exception of perhaps one, must have been open for well over 5 days, each tasting completely oxidated and stale.
I spoke to one of the waiters who said they actually take opened bottles from flights and keep them for typically a week before they are binned. It's such a shame because the selection is world class, but would highly suggest they offer a smaller selection of wines but ones are destined to be consumed within 24 hours of open.
