Chateau Palmer Margaux 2017

When the Mähler-Besse and Sichel families' syndicate acquired Palmer in 1938, they inherited an estate already defying Médoc convention — 47% of the vineyard planted to Merlot on the Cantenac-Margaux plateau's finest Gunzian Garonne alluvial gravel croupes, the very parcels where orthodoxy demands Cabernet Sauvignon. That deliberate inversion is the engine of Palmer's identity. The 122 plots across Cantenac, Issan, and Margaux sit on 18 distinct gravel, sand, and clay soil types, with the 30-hectare plateau behind the château offering gravel-over-clay and the Issan sector delivering higher pure-gravel content; the Gironde estuary moderates temperature swings, extending phenolic ripening across vines averaging 38 years old, with select blocks exceeding 70. The 2017 vintage marks Palmer's first year of full biodynamic certification — a watershed that sharpened terroir transparency across the estate. Hand-harvested fruit was fermented plot-by-plot in 42 temperature-controlled stainless vats using indigenous yeasts, with no sulfur additions at harvest; the Grand Vin then aged 20–22 months total: the first year in 225-litre French oak barriques at under 50% new wood, the second in 30-hectolitre oak vats to integrate without over-oaking. The wine was bottled unfined and unfiltered. No other Third Growth in the Médoc plants Merlot at this proportion on premier gravel, then certifies biodynamically — 2017 is the precise vintage where both commitments converged for the first time.
