after all, is a great wine really all that much nicer than a good one?fn5 The Netflix documentary Sour Grapes is a fascinating insight into this world. A crooked, though brilliant, Indonesian wine connoisseur called Rudy Kurniawan was able to replicate great burgundies by mixing cheaper wines together, before faking the corks and the labels. He was rumbled only when he attempted to fake wines from vintages that did not exist. I am told that it is possible to detect a forged Kurniawan wine by analysing the labels, but not by tasting the wine.
