A great learning kit for aspiring Cognac connoisseurs, this set of 4 quarter-size bottles demonstrate the classic stages of barrel aging of this Brandy (distilled wine) from the Cognac region of France: VS, VSOP, Napoleon and XO, each bottling made from the same wine sources. The progression in richness, smoothness, harmony and toasty expressions are dramatic and enlightening. A great party surprise conversation exercise as the denouement (unwinding phase) of a luxurious dinner! Serve them in a snifter and swirl each serving for a couple of minutes before sniffing and tasting. Great with short bread, mild cookies and dried fruit.
