The different grape varieties in the different parts of the vineyard are harvested only when their ripeness has been closely studied. It is not unusual for harvesting to spread over several weeks, so that the grapes may be picked at optimum richness. Since 1978, the wines of Château Villars are aged in oak barrels, one third of which are renewed every year. Very strict technical control is observed in the greatest detail from the vineyard until bottling, so that Château Villars wines remain faithful representatives of the family of Great Bordeaux Wines.
