Exclusively owned by the Joly family, the gemlike 7-acre Coulée de Serrant is its own appellation, one of the great monopoles of France. The vineyard was planted in 1130 by Cistercian monks and today consists of vines aged from 35 to 80 years old. The old small monastery on the property still exists, and a few hundred meters away, the castle of La Roche aux Moines was built and dismantled during the wars of religion.

Always considered a rare and unique product, the estate's wines were celebrated by Louis XI and Louis XIV as among French’s finest white wines. Even today the vineyard is cultivated partly by hand and partly by horse because of the steep slopes overlooking the Loire.

In 1977 Nicolas Joly left a career in finance and returned to his family’s historic estate. Initially troubled by small but noticeable issues with the vines, he stumbled across an old book on biodynamics and was fascinated, quickly experimenting with it on a small vineyard parcel. The results were extraordinary. Joly immediately moved to apply these principles and practices across the estate, and Clos de la Coulée de Serrant has since become the touchstone for biodynamics around the world.
