The majority of the vineyard is still dry farmed. Though the vineyard has been reasonably maintained over the years, it is showing its age. Many of the oldest vines are very brittle and have either died or just plain toppled over due to imbalance.

Rehabilitation activities have started. The objective is to maintain as many of the old vines as possible. The plan is to plant 300-400 rootings every year and the following year, graft bud wood from the existing vines to the year-old rootings.


Classic Italian Field blend, Primary cultivars include: Carignan, Zinfandel and Grand Noir; secondary cultivars found and identified by UCD DNA testing include: Clairette Blanche and Peloursin; other “odd ball” cultivars found and identified by UCD DNA testing include: St. Emilion, Beba, Listan Blanc and Durif Blanc.

The Durif Blanc is the only “known” vine to exist in the world. There may be others. However, after extensive research, none have been identified anywhere.
