Château Le Puy has farmed this corner of Bordeaux's Côtes de Francs since 1610, biodynamic before the word existed, with horses in the vineyard and Demeter certification today. They bottle as Vin de France rather than chase appellation rules, and each cuvée is named for a family ancestor. Marie-Cécile is their white, made from Sémillon farmed the same idiosyncratic way as the reds: native yeasts, no fining, no filtration, minimal sulfur. The result is a full-bodied, characterful white with real limestone-driven cut. This 2023 is the kind of singular, alive Bordeaux white you rarely see.
