Conversation so far:
Did he own any wine from TJ's vineyard?
In 2005, U.S.
art and wine collector Bill Koch, who had bought some of the bottles attributed to Thomas Jefferson.
How does this all relate to Hardy?
Inquiries at Chicago Wine Company and Farr Vintners came up with the result that all four of Koch's bottles originated with Rodenstock.
So Hardy sold them to Koch.For how much?
a U.S.
wine auction house (Chicago Wine Company) and a UK rare wine dealer (Farr Vintners), and paid a total of about 500,000 U.S.
dollars for them.
Were they altered ?
Koch hired a retired Federal Bureau of Investigation (FBI) agent to form a team to start private investigations into Rodenstock's sales of wine.

Question: What did the team find?
Self-contained rewrite: What did the FBI team find?
