The Paradis Casseuil terroir is mainly linked to the molasse of the Agenais, a typical geologicalformation of the Entre-Deux-Mers plateau, but also to the Asteria limestone, which appears at the place called "Le Paradis". Over the course of the blocks, these two formations have a wide variety of sedimentary facies: sandstone limestone, marl, clay with calcareous nodules, variegated magnesian molasse, etc. The soils that develop here are usually very clayey and rich in calcium. They thus benefit from excellent structural porosity, which is favourable to deep root development, but also from a certain coolness.
