Kurniawan began buying and selling large amounts of rare
wines in the early part of the 2000s, spending as much as $1 million a month buying
auction lots by 2006. At the same time, he began hosting tastings of rare wines with other collectors; he showed so much affinity for the ultraluxury
Burgundy producer,
Domaine de la Romanée-Conti, at these events that he became known as "Dr. Conti". At this time, he was described as possessing "arguably the greatest
cellar on Earth." Eventually, he wound up consigning lots with John Kapon in two major auctions at
Acker, Merral & Condit in 2006, netting $10.6 million ($ in dollars) in the first and $24.7 million ($ in dollars) in the second. beating the previous record by more than $10 million. A few days after the second sale, Kurniawan secured a loan for $8.84 million ($ in dollars) from Acker Merrall & Condit, secured by the wine and art in his collection. Ponsot later met with Kurniawan and was left wondering if Rudy was actually a counterfeiter or simply the last person to innocently handle counterfeited wine. He also defaulted on a $10 million loan from the auction house Acker, Merrall & Condit, where he sold much of his wine, including the withdrawn Ponsot sale. In February 2012, Spectrum Wine Auctions had to withdraw several lots of wine, worth an estimated $785,000, from an auction in
London when allegations emerged that they were consigned by Kurniawan through a second party. ==Arrest==
