Auction update: Can the Loire compete with Burgundy?

auction update – in association with iDealwine

As collectors diversify, the Loire is emerging as a region to watch, with names such as Domaine Dagueneau and Clos Rougeard to the fore.

Loire wines are no longer the secondary market’s hidden gems. While Burgundy prices softened in 2025, the Loire continued to gain momentum. At iDealwine, auction volume and value for Loire wines rose 20% and 26% respectively, while average bottle prices remained stable at €78.

Dry whites dominate the secondary market, accounting for around half of all auction transactions. Chenin Blanc and Sauvignon Blanc remain the region’s defining grapes, though red wines are proportionally more prominent at auction than in vineyard plantings.

Cabernet Franc-based reds represented 41% of auction volumes, despite accounting for only around 20% of Loire vineyard area; and Loire Pinot Noirs tend to be over-represented at auction too.

Older vintages also continue to command strong sale prices. Bottles over 20 years old represented 15.5% of volumes sold, with average prices climbing to €105.

At the same time, younger wines remain highly active on the market, with vintages under 10 years old accounting for 58.5% of volumes traded, a notably higher proportion than in other French regions.

The Loire’s appeal to wine connoisseurs is also closely tied to the dominance of organic, biodynamic and natural winemaking philosophies among its leading estates. Wines from certified organic or biodynamic producers accounted for 58% of volumes sold and 69% of total value at auction in 2025.

Meanwhile, natural wines represented 21% of volumes and nearly one-third of total value.

That trend is reshaping the hierarchy of sought-after producers. In Auvergne, near the source of the River Loire, natural wine grower Aurélien Lefort surged from 24th to sixth place in iDealwine’s most-coveted rankings last year, reflecting rapidly expanding international demand for his micro-production wines, which achieved an average auction price of €345 per bottle.

Fellow Auvergne producer Vignoble de l’Arbre Blanc also saw strong momentum, with 277 bottles sold at an average price of €85, a remarkable result for a 1.6-hectare estate working volcanic terroirs.

The Loire’s classic names remain equally influential. In Sancerre, the late Edmond Vatan continues to command cult status through the microscopic production of Clos de la Néore. Only 186 bottles were sold at auction in 2025, many of them mature vintages, with bottles over 10 years old averaging €272.

Domaine François Cotat, another benchmark Sancerre estate, maintained strong collector demand at more accessible price levels. In Anjou, top hammer prices were for Richard Leroy, Josette Médau and Pierre Weyand, while in Muscadet Jérôme Brétaudeau’s wines reign supreme.

Despite the growing breadth of Loire wines in the auction sector, a few benchmark estates continue to dominate collector attention. Clos Rougeard remains the region’s undisputed heavyweight, generating more than €300,000 in total auction value in 2025, with 1,284 bottles sold. Prices for the Saumur estate stabilised slightly, averaging €236 per bottle, down 2% year-on-year, although older vintages continued to command exceptional prices, averaging €286 for bottles over 20 years old. Domaine Dagueneau followed close behind, generating just under €100,000 in total value from 665 bottles sold.

Loire Visionary

Among the lots attracting the fiercest competition were several wines from Domaine Dagueneau, the Pouilly-Fumé estate founded by the late Didier Dagueneau in 1982. Long considered a visionary in the Loire, Dagueneau transformed perceptions of Pouilly-Fumé through obsessive vineyard work and radical precision in the cellar.

At a time when the appellation was often overshadowed by the global reputation enjoyed by neighbouring Sancerre, Dagueneau established a global reputation for wines capable of rivalling the world’s finest dry whites.

His methods were uncompromising. Following strict fruit selection, the wines were fermented and aged with meticulous attention to lees contact and élevage, producing Sauvignon Blancs prized for their flinty minerality, complexity and remarkable ageing potential.

Dagueneau’s sudden death in 2008 left the estate in the hands of his son, Louis-Benjamin Dagueneau, who has continued to refine the estate’s singular style while preserving its identity. In 2016, he was named Winemaker of the Year by French wine magazine La Revue du vin de France. A year later, his wines were released as Vin de France following a disagreement with appellation rules.

Ten years on, in iDealwine’s April 2026 auctions, collectors fought ferociously for Louis-Benjamin’s flagship wines, with older vintages vinified by his father Didier now collector’s items, commanding a premium.

Top hammer prices included Dagueneau’s Silex wine, with a magnum of the 2015 vintage fetching €428, 37% above estimate, while bottles from multiple vintages sold for between €170 and €239. Pur Sang vintages from 1994, 2014 and 2020 also significantly exceeded expectations, while mature bottles of Buisson Renard and En Chailloux also generated considerable interest.

The strong performance of Domaine Dagueneau reflects broader momentum behind Loire wines at auction. Ranked fourth by volume at iDealwine in 2025, the Loire accounted for 18,082 bottles sold, scaled to 750ml.

As collectors diversify beyond Burgundy and Bordeaux, the Loire is evolving from a niche category into one of the fine wine market’s most dynamic regions, driven equally by historic estates and a new generation of cult natural wine producers.
