Château Giscours 2018 is the grand vin of this Third Growth (Troisième Cru Classé) estate in Margaux, a property with deep roots and a sizeable holding—around 80 hectares planted within a broader 400-hectare estate. In 2018, the wine drew consistently strong critical attention, landing in the mid-90s with several excellent reviews, including James Suckling’s 97 points and Wine Enthusiast’s 96.
The aromatic profile leans classic Margaux with a riper, year-marked depth. James Suckling notes “black currant, dried-blueberry, oyster-shell, black-olive, black truffle, and bitter-chocolate aromas,” and calls it “powerful and chewy yet very polished.” Wine Spectator (95 points) highlights lifted floral tones—“violet and lilac notes”—alongside “creamed plum” and “mulled blackberry and black currant,” finishing long with savory accents.
Texture and structure are central themes. Decanter (95) describes a “luxurious, confident Giscours” with “swirls of smoke backed up by spice” and “an effortless quality to the tannins,” while stressing it is “definitely built to last” and “easily stands up to the 2015 and 2016.” Jane Anson (95) similarly frames it as a warm-year expression: “clear… this was a hot year,” delivering a “gourmet expression” with “muscular tannins” that “needs a few more years in bottle.”
Vinous’ Neal Martin, tasting both early and later, notes it “contains a high percentage of Merlot this year,” carries 13.8% alcohol, and was “matured in 50% new French oak,” calling it “a classic Giscours.” Jeff Leve (95) reports the blend as 55% Cabernet Sauvignon, 39% Merlot, 6% Petit Verdot and suggests it can age “at least 3 decades.”
Most reviewers recommend patience: best drinking windows commonly begin around 2024–2027, with longevity into the 2030s and beyond for well-stored bottles.
