2021

When Baroness Philippine de Rothschild and Eduardo Guilisasti Tagle formalized their joint venture in 1997, they imposed a single constraint that shaped everything: one terroir, one bodega, one team, one wine — the French Château concept transplanted to the foot of the Andes. That discipline is why only ~50% of estate fruit ever reaches this label. The Puente Alto site sits at 620–650 m elevation on classic Andean alluvial fan deposits — loamy clay to 50 cm, then sandy loam, gravel, and rock — soils so poor and free-draining that vines, some ungrafted and planted as early as 1978, are forced deep for water, concentrating extract while the Andes' diurnal swings preserve acidity at 15% ABV. Hand-harvested fruit is cold-macerated in parcel-specific stainless steel tanks, then fermented and transferred entirely by gravity — no pumps — before spontaneous malolactic fermentation occurs directly in French oak barrels (70–73% new, 20 months), integrating wood from the first contact with the finished wine. The 2021 blend — 71% Cabernet Sauvignon, 22% Carmenère, 5% Cabernet Franc, 2% Petit Verdot — runs cooler and more restrained than the preceding drought vintage, with the Carmenère's roasted-pepper and dark-spice register woven tightly into the structure rather than forward on the nose. No Bordeaux or Napa peer can legally include Carmenère; that variety, lost to phylloxera in France and rediscovered in Chile, is the flavor signature no other first-growth-tier wine can replicate. Drink 2026–2046.
