Why it matters
The producer
Don Melchor is a single wine from a single vineyard in Puente Alto, on the Maipo River's northern bank. Concha y Toro created it in 1987 as their first ultra-premium release and the first wine they aged in French oak barriques. What grew from that decision is the most awarded Chilean wine in Wine Spectator history and, as of 2024, the first Chilean wine to rank number one on that magazine's annual Top 100.
The wine is named for Don Melchor de Santiago Concha y Toro, the Chilean ex-Minister of Finance who founded Viña Concha y Toro in 1883 by importing French vine cuttings from Bordeaux. That original Bordeaux connection runs forward through the label's entire life: Bordeaux consultant Jacques Boissenot advised on the inaugural 1987 vintage, and today his son Eric Boissenot holds the same role. Enrique Tirado has been winemaker since the 1997 harvest and since 2019 has led the operation as CEO of a standalone entity within the Concha y Toro group.
Place and vineyards
Where the wines begin
Puente Alto sits at the upper end of the Maipo Valley, in the sub-zone called Maipo Alto, at approximately 650 metres elevation. The vineyard occupies the third alluvial terrace of the Maipo River's northern bank, where the river's historical deposits left soils of loamy topsoil over deep river gravel. That gravel layer drains freely and keeps fertility low, which stresses the vines into producing small, densely flavoured fruit. On the label, this address appears as Maipo Valley, the broader appellation; Maipo Alto is the sub-zone that defines the elevation and the gravel profile.
The Andes to the east drive large diurnal temperature swings across the growing season. Hot days push ripeness; cold nights slow it and preserve acidity. At 650 metres, the site sits high enough for that cooling effect to matter in every vintage.
In the cellar
Vineyards and cellar
The 151 micro-plots allow Tirado to treat the estate as a collection of small parcels rather than a uniform block. Each plot is harvested, fermented, and aged separately. Only after that process is the final blend assembled, and between thirty and fifty percent of total fruit is left out of the wine each year.
Oak comes from French forests: Allier, Tronçais, and Nevers. The 2021 vintage spent fifteen months in barrel, with approximately sixty-eight percent new wood, followed by a further year of bottle aging before release. The 2022 vintage used seventy-eight percent new French oak. The high proportion of new wood is a deliberate choice for a wine built around Cabernet Sauvignon from a warm-climate, high-elevation site: the wood feeds tannin without flattening the fruit, provided the fruit concentration can carry it. On this vineyard, it can.
Wines to know
The range in view
Don Melchor produces one wine: a Cabernet Sauvignon-dominant red from the Puente Alto estate. The 2022 vintage is composed of ninety-five percent Cabernet Sauvignon, three percent Carmenère, one percent Merlot, and one percent Petit Verdot. The Carmenère adds a herbal depth that is distinctly Chilean; the Merlot and Petit Verdot contribute texture and colour without driving the blend. Cabernet Sauvignon, grown at altitude on gravel soils, is the whole argument.
The wine is aged over two years from harvest to release: fifteen months in French oak barrels, then a further year in bottle. That timeline is built into the release schedule, which is why vintages come to market later than most Chilean reds. The 2021 vintage ran to approximately eighteen thousand cases, which places it firmly in the range of a serious estate wine produced at meaningful commercial scale.
