Our Old Vine Zinfandel blends vineyards planted on the Dry Creek bench and the cooler southwest Alexander Valley. Although “old vine” is often loosely interpreted in the wine industry, our benchmark is minimum 50 years. However, the average age of our vines is approximately 70 years old. True old vine Zinfandel is distinguished by head-trained vines with thick, gnarled trunks and is planted with ancient clones dating back to the turn of the century.
