Domaine Arnaud Lambert is based at Brézé in the Saumur appellation (Anjou, Loire Valley), producing both Saumur Blanc (Chenin Blanc) and Saumur-Champigny (Cabernet Franc red). Brézé is a recognised terroir for structured, mineral Chenin Blanc the town's château and surrounding vineyards occupy tuffeau limestone soils that produce wines with a distinctive vertical, saline quality quite different from the more fruit-forward Loire Chenin produced further west. Arnaud Lambert farms organically.

The Lambert range at Bouchon is anchored in the Saumur blanc tier Les Parcelles covers the village and premier cru levels with Saumur-Champigny as the Cabernet Franc counterpart. For programmes building a Loire white wine selection beyond Muscadet and Sancerre, Saumur Blanc from Brézé represents the high-acid, age-worthy Chenin Blanc tier that rewards comparison with white Burgundy. Arnaud Lambert provides the artisan-estate reference point for this terroir in the catalogue.
