Plantgrape describes a fertile, rather productive variety with soft shoots needing trellising, well adapted to gravelly soils, and notes that in southern areas it requires regular watering. That attributed note is not an irrigation amount or schedule.
Plantgrape notes that historical coulure linked to a stigma malformation was eliminated in France through selection work. That history applies to French selected material and should not be generalized to all plantings.
