How to spot a fake wine

To make a 1945 Mouton Rothschild, mix two parts Château Cos d’Estornel to one part Château Palmer and California cabernet. That was the strategy of Rudy Kurniawan, a wine fraudster, who poured his mixture of wines into old bottles with fake labels and sold them to gullible collectors. In 2014 he was sentenced to ten years in an American prison and ordered to forfeit $20m and to pay another $28m to victims.
