As some of the members have alluded to, wax would not prevent 'corked' wine. Traditionally, wax served as a perfect air tight seal in such bottles as Vintage ports, long after the corks disintegrated. However I suspect the reason for the wax on the new wide lipped bottles like the Beringer is more for cosmetics and consumer appeal since it's just a dab on top.
