Henriot L’Inattendue 2018 is the house’s focused take on a single site and a single grape: a blanc de blancs made from **100% Chardonnay from the Grand Cru village of Chouilly** in the Côte des Blancs. It’s bottled as **Extra Brut**, with a notably low **2 g/L dosage**, and is reported to spend **a minimum of four years aging** before release. Alcohol is generally listed at **12%** (one review cites **12.5%**).

The 2018 vintage context matters here. Champagne 2018 was widely described as an outstanding year, and in a **blind tasting of 37 wines from the vintage**, L’Inattendue **shared the top position**, underscoring its standing among its peers.

Critical reception is strong across the board, with an excellent headline score from Decanter. At **95 points**, **Decanter (DWWA 2025)** calls it “**expressive**,” led by “**yellow plums, apples, white peaches and brioche**,” and emphasizes structure: “**tightly wound tension of mineral texture and lemon peel acidity. Stylish and long.**” That combination—ripe fruit, brioche-autolysis, and drive—captures the wine’s intent: generosity held in check by Chouilly’s chalky cut.

**Wine Spectator** also rates it highly at **94 points**, leaning into its precision, noting “**rapierlike acidity**” and a detailed flavor set—“**glazed apple, baked peach and financier**,” plus “**lemon curd, crystallized honey and pastry cream**”—with a drink window running **through 2038**.

From a Master of Wine perspective, **Essi Avellan MW** lands at **94–95 points**, highlighting “**an elegantly toasty nose**” with “**refined autolytic complexity**,” then praising the mouthfeel as “**at once brisk and creamy, showcasing impeccable balance**.”

Overall, L’Inattendue 2018 reads as a rigorously dry, Grand Cru Chardonnay Champagne that pairs clear ripeness with firm, mineral tension—already impressive, and built to evolve.
