 The vines seems to thrive particularly well on stony, calcareous soils with the main viticultural hazard being a susceptibility to powdery and downy mildew.In the 19th century, Persan was widely planted throughout the Savoie region and Isère region until the phylloxera epidemic at the end of that century greatly reduced its numbers.It is still found in the Savoie region today where it is a permitted variety in the "appellation d'Origine Contrôlée" wines of the Vin de Savoie AOC as well as the "Vin de Pays d'Allobrogie" zone but plantings were down to just 22 acres (9 hectares) in 2012.
