Covert Estate is in the eastern hills of the Vacas Mountain Range, in the Coombsville Appellation. It was started by three couples with backgrounds as wine collectors or vintners. Covert applies Bordeaux winemaking to Coombsville terroir.
Château Léoville-Las-Cases is a Second Growth Bordeaux with nearly a First Growth reputation. Its wines are outstanding, and many collectors consider Léoville-Las-Cases in its best vintages to equal First Growth wines of the appellation.
