Each vineyard must contain at least 60% Marsanne and Clairette, which are the two main grape varieties of the appellation. Marsanne originates from the north of the Rhône Valley and has acclimatised perfectly to growing by the sea. It affords fine and elegant aromas punctuated with notes of white flowers as well as a long finish in the mouth. With time, it offers subtle honeyed notes. Clairette, of Provençal origin, appreciates the thin, dry, chalky and less fertile soils of the Cassis wine-growing area. It adds to the freshness of the white wines of Cassis. It gives them notes of aniseed, garigue, acacia honey and white-fleshed fruits. It also gives them roundedness and body.
