Between 2004 and 2009, Kurniawan made fake wines which he then sold for $1.3m, also using the counterfeit wines as collateral to secure a loan of $3 million.
He is believed to have sold 12,000 bottles at auction in 2006.
Over the course of the trial the court heard how Kurniawan’s home in California was a “factory” for fake wine production, heard testimony from billionaire Bill Koch and Burgundian winemakers Laurent Ponsot and Aubert de Villaine. The 37-year-old faces up to 40 years in jail.
The jury took less than two hours to find the Indonesian national guilty.
This week Judge Richard Berman set a date of 24 July, delaying the fraudsters sentencing for a third time because he was dissatisfied with the level of detail provided by prosecutors in the case, it has been reported.
