The domaine is spread across eight communes. These diverse holdings give the Brochards a range of soils. Terres blanches, or Kimmeridgian marl, gives powerful wines. Silex, or flint, yields wines with a strong mineral character, and chalky caillottes bring attractive aromatics to the wines.

Sauvignon Blanc Les Carisannes comes from a five-hectare vineyard in Bannay near the Sancerre appellation. The name Les Carisannes is a contraction of the names of the three sisters and grand-daughters of Henry Brochard: CARoline, ISAbelle, and ANNE-Sophie. Stony soils and vinification in stainless-steel tanks yields a fresh tasting wine with notes of minerals.
