The area's Mediterranean climate, and its exposure to sunlight in particular, is ideally suited for ripening grapes. Furthermore, the influence of Mont Ventoux on the wide variation in day and night-time temperatures during the ripening season means that this region has the ideal conditions for the muscat to obtain its bluish colouring and concentrated aromas. The night-time coolness contributes particularly to preserving the aromas.

The pruning of the vine limits the yield, allowing for optimal ripening of the grapes. Furthermore, particular care is taken to manage the foliage. This work makes it possible to achieve an optimal level of foliage which is one of the elements necessary for a good photosynthesis of sugars, the organoleptic components of the grape and the anthocynanins which give the berries their colour.
