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.

Sancerre Tradition comes from six different communes in the Sancerre appellation from approximately 40% limestone, 30% flint, and 30% clay. All the parcels are estate-owned and have an average vine age of 30 years. Grapes are destemmed and pressed pneumatically with vinification entirely in stainless-steel tanks.
