Father-and-son team Bernard and Benoit (part of the great Landron clan) farm around 25 hectares to the north-east of Nantes. Organic since 2010, they have a patchwork of vineyards mostly situated around the towns of Ligne and Udon. Soils are mostly a mix of decomposed volcanic material; mica schist, granite and gneiss. Benoit started making Pet-Nat in 2013 and has proved to be rather good at it.
