The geographical area extends across sedimentary Lorraine, to the east of the Paris Basin, with four major north–south calcareous cuesta ridges: the Côtes de Meuse, the Côte de Moselle, the Côte infraliasique, and the Côte de Lorraine.
The soils are argillaceous-calcareous, developed on a marly substrate with a clay content of at least 25%, and enriched by colluvial material derived from the scarp faces or from the harder formations situated above.
The temperate continental climate features cold, dry winters with a mean temperature below 3 °C, and spring frosts that are relatively infrequent according to the 1986–2010 climate normals.
Summers are characterised by low warmth, with mean temperatures of around 18 °C at their hottest (July mean, 1986–2010 normals), and are often relatively storm-free; the coolness of summer nights and the rarity of very hot days promote the ripening of the fruit and the achievement of optimal sugar levels.
Mirabelle plum trees occupy specific positions such as the marly embankments of east- to south-east-facing escarpments, the well-ventilated slopes of outlier hillocks, and elevated positions on the hills, which disperses the orchards across the area.
