A vineyard was a place where grapes were grown for making wine, raisins, or table grapes. A vineyard that produced grapes for wine production typically employed vigneron, or winemakers, who oversaw the crops and wine fermentation process.
The Picard family vineyards, located in La Barre, France, were well-known for wine production, notably for their Chateau Picard vintage. There was also some relation to Chateau La Barre. The vineyard's vigneron during the mid-24th century was Robert Picard. (TNG: "Family"; Star Trek Nemesis)
