Natural factors

Four geological categories outcrop in the zone: sandy-gravelly alluvium, lacustrine clays, yellow sands with conglomerates, and arenaceous-marly turbidites.
On the steep clayey slopes, loamy-silty Entisols dominate — strongly calcareous, sub-alkaline, and low in organic matter.
On the ancient alluvial terraces, Inceptisols (Haplustepts) develop with a well-balanced texture, low in skeletal material and carbonates.
Vines are cultivated up to 450 m a.s.l. for red-wine varieties and 500 m a.s.l. for white-wine varieties; valley floors are excluded from the appellation.
Mean annual rainfall is 897.54 mm (century-long average), rising to 937.1 mm over the last decade mainly as a result of increased winter precipitation.
