Each JCB wine is known by a number. And each number has deep significance for Jean-Charles Boisset, the collection's creator and namesake. Jean-Charles' philosophy of wine has been profoundly shaped by the wine region where he was born and raised: Burgundy's famous Cote d'Or, which translates to the Gold Coast. No. 21 honors this connection and heritage, for 21 is the French government's "Department" number for the Cote d'Or.
