Domaine Didier Dagueneau’s Buisson Renard 2023 is a single-vineyard Sauvignon Blanc from Saint-Andelain in the Pouilly-Fumé sector of France’s Upper Loire. The domaine, founded in 1982 by the late Didier Dagueneau, built its reputation by pushing Sauvignon Blanc beyond the region’s traditional, lighter style through meticulous viticulture and élevage. As Alliance Wine notes, the estate became “iconic” and developed “a cult following,” with wines known for “power, precision,” and a distinctive “flinty ‘smoky’ minerality,” as well as “remarkable age-worthiness” (Alliance Wine).

Buisson Renard is rooted in that house style and in its site: flint-rich (*silex*) and limestone soils that emphasize the “fumé” character. Although it comes from prime Pouilly-Fumé vineyards, it is labeled Vin de France, reflecting what Alliance Wine describes as the domaine’s independent stance toward appellation rules. The wine is made from 100% Sauvignon Blanc (Alliance Wine; Les Passionnés du Vin).

In the cellar, the approach is deliberately hands-off but exacting. Grapes are hand-harvested “in multiple passes (triage) for optimal ripeness and freshness,” then the must ferments spontaneously with “indigenous yeasts” (Alliance Wine). Ageing is on fine lees in a combination of stainless steel and neutral oak demi-muids, intended to add texture “without” overt oak impact, with gentle bâtonnage (Alliance Wine).

In terms of flavor and structure, Alliance Wine describes “expressive aromas” and a palate that reads as “exceptionally pure and energetic,” with “bright acidity,” “subtle saline nuances,” and a “long, precise finish”—a profile consistent with the vineyard’s wet-stone, flint-driven signature.

Professional critic reviews and scores for the 2023 vintage were not available in the provided material, so no “excellent reviews” can be cited yet. Even so, the surrounding context is clear: this is a tightly sourced, carefully raised Sauvignon Blanc designed to translate flint terroir with concentration, precision, and staying power.
