There are three main soil types in the lands of Tavel :
• quartz round pebbles on the villafranchienne terrace : Vallongue.
• flat lime stones originating from the Barremien crumbled hill-stones : Campey, la Vaute, Romagnac, Torette, la Vau et Clos, Les Vestides, les Comeyres, Vaussières.
• Astien fluvial sands : Vaucrose, Vaucrose et Vacquières, Genestière, Codoyères, Le Palai, Roquaute, Bouvette, Olivet.
Some parcels have mixed subsoils, as in Cravailleux, where round pebbles and flat stones can be found as well as Astien fluvial sands and pebbles.
The soils are mostly poor in humus and organic matter, making Tavel an ideal land for winegrowing.
Pebbles and stones have a definite effect on the vines : Barremian flat stones are whitish and tend to reflect most sunrays during the day, activating the maturation of the berries. As for Villafanchian pebbles, they accumulate heat during the day that they release during the night.
