Chateau Le Barre was an estate red wine produced at the Picard family vineyards in La Barre, France. The head vigneron or winegrower during the mid-24th century was Robert Picard. This chateau's wine was trademarked and bottled at a castle. One particularly note worthy year of this wine was 2294.
When Jean-Luc Picard returned to Earth to meet his family in 2367, he sampled a glass of Chateau Le Barre 2347 and mistook it for a 2346 vintage. Robert Picard gave Jean-Luc a bottle of the '47 when the latter returned to the USS Enterprise-D. (TNG: "Family")
