Located in Martillac, in the Pessac-Léognan appellation, Clos Marsalette is jointly owned by Count Stephan von Neipperg and Didier Miqueu.

This vineyard sits magnificently on gravelly rises deposited aeons ago by the Garonne. Offering a great diversity the subsoil is composed of marine sediment from the Miocene and Pliocene epochs (5 to 15 million years ago) in the form of shelly sand with a bit of clay, fawn-coloured sand, and multi-coloured clay.

 Clos Marsalette's vineyard which covers an area of 12,30 hectares (for the red wine) plus 1,30 hectares (for the white wine) is also looked after expertly in order to produce a wine reflecting the typicity of this Terroir.
