The tastings were conducted from the collection of Hardy Rodenstock, a German wine collector who later was embroiled in a counterfeit wine controversy involving a bottle reported belonging to Thomas Jefferson.
While Peppercorn's and Sutcliffe's concerns were never proven, and were disputed by Rodenstock, the current manager of Château Pétrus, Christian Moueix, confirmed that the estate has no records of producing imperials during those vintages.
