The geographical area extends across more than 300 communes representing a third of the administrative region of Brittany, divided into three highly fragmented sub-zones.
The geographical zone rests entirely on the Armorican Massif and excludes marshlands, areas dominated by deep silts, and superficial formations on sandstone and granite.
The climate is strongly oceanic, with mild temperatures and regular precipitation remaining below 1,100 mm, owing to an altitude limited to 120 metres.
Apple trees are planted on shallow soils or soils with a sandy structure or a high proportion of coarse elements, without significant signs of hydromorphism.
Variations in temperature and relative humidity between seasons are slight.
