Domaine Didier Dagueneau from the village of Saint-Andelain in the Pouilly-Fumé appellation is considered one of the most consistent names in Loire Valley Sauvignon Blanc, defined by strict grape selection, work on small parcels, and a strong focus on terroir. Founder Didier Dagueneau was known for insisting on manual vineyard work, low yields, and meticulous control over every production step, which resulted in wines of exceptional purity and minerality.
