Chateau Ducru Beaucaillou 2021

In 2021, Bruno Borie made a decision unprecedented in the estate's recorded history: 98% Cabernet Sauvignon, 2% Merlot — the most Cabernet-dominant Grand Vin ever bottled at Ducru-Beaucaillou, a deliberate response to a cool vintage that rewarded the appellation's king grape over the earlier-ripening Merlot.

The vineyard sits on one of the Médoc's deepest gravel beds — 6–8 metres of Günz-period quartz pebbles, lydian jasper, flint, and agatoids deposited by the ancient Garonne roughly two million years ago, over Oligocene mud and Eocene limestone. This extreme drainage forces vine roots deep, concentrating mineral tension and suppressing excess vigour; the Gironde estuary's four daily tidal movements buffer the microclimate against frost and summer heat spikes.

Vinification proceeds parcel-by-parcel in variable-volume stainless steel tanks, with multiple manual sorting passes including optical selection, a minimum seven-day maceration, and gentle extraction at moderate temperatures. Malolactic fermentation is completed in concrete and stainless vats before the wine moves to 100% new French oak barriques (225L) from five cooperages for 18–20 months — a counter-cultural commitment Bruno Borie has maintained while simultaneously farming fully organic since 2018.

The 2021's near-monovarietal Cabernet structure produces extraordinary linear precision and graphite-edged finesse; only 27% of total vineyard output was selected for the Grand Vin. Drink 2028–2055.
