In November, Netflix will air Sour Grapes, a documentary about Rudy Kurniawan who received a 10-year prison sentence for counterfeiting vintage wine. Kurniawan was a connoisseur and a wine expert who befriended other wealthy collectors. A New York auction house sold $35 million of Kurniawan’s wines in 2006. Kurniawan prepared the fakes in his kitchen. He had a complete in-house factory with bottles and labels. His expertise completed a shrewd operation that fooled many including billionaire William Koch, who purchased quite a few of his wines and testified at the criminal trial. It is estimated that there may be as many as 10,000 of Kurniawan’s bottles still in private collections.
