Château Picard was the Picard family vineyards in La Barre, France. (PIC: "Remembrance") The head vigneron or winegrower during the mid-24th century was Robert Picard, until his death in 2371. Before him, the vigneron was his father Maurice Picard. (TNG: "Family"; Star Trek Generations)
Two vintages they were known for producing was the estate red wines Chateau Picard and Chateau La Barre. Chateau Picard was available to the public since at least 2249, and one particularly noteworthy vintage year of Chateau La Barre was 2294. (DIS: "The Vulcan Hello"; TNG: "Family")
After resigning in protest from Starfleet in 2387, Admiral Jean-Luc Picard moved to Château Picard and took over the vineyards. Unlike the aversions to the use of modern technology that his father Maurice and his older brother Robert had on the family property, Jean-Luc employed and installed modern conveniences, such as automatic watering vehicles for the fields, surveillance devices to provide security feeds to quickly view the entire property, holographic screens (such as one in the kitchen to easily watch the news while preparing meals), and most poignantly, a kitchen replicator, which his mother Yvette Picard and sister-in-law Marie Picard had argued for during their marriages to their respective husbands.

Background information Edit
According to the album, it had been tended by the family since the first half of the 23rd century. In 2234, the spring bottlings of this vineyard were tasted at a wine tasting at Starfleet Academy organized by Robert Picard.
Before 2305, the Bordeaux wines of Chateau Picard were awarded the Appellation Bordeaux contrôlée. The same year, the vinery was also awarded a "Certificate of Excellence in Winemaking" from the Terran Winemakers Association for the 2305 vintage of their Bordeaux. The certificate mentions the appellation.
