Clos Saint-Jean’s Châteauneuf-du-Pape “Deus Ex Machina” 2023 is the domaine’s high-powered flagship expression from the Southern Rhône, built around very ripe fruit, old vines, and a deliberately concentrated style. The blend is the house’s classic 60% Grenache and 40% Mourvèdre, with the Grenache aged in concrete and the Mourvèdre matured in barrel, a split élevage that helps keep the wine’s fruit breadth while adding grip and seasoning.

This is also a notably limited wine. Wine Spectator reports “380 cases made, 54 cases imported,” underlining its scarcity in many markets.

The strongest published review is an excellent 98-point score from Jeb Dunnuck, who calls it “full-bodied” and praises its “pure, layered, graceful mouthfeel,” adding that it shows “more mid-palate depth, richness, and length than just about every other wine in the vintage.” Dunnuck also emphasizes its “flawless balance,” suggesting it is “approachable today yet will be even better with 4-5 years of bottle age,” with a long runway ahead (Drink 2025–2045).

Other critics echo the scale while describing the details differently. Wine Spectator (95 points) frames it as “a concentrated, showy red, with a caressing texture,” shaped by “cherry, mulled plum, licorice and baking spices,” then finishing with “warm stone, iron and sandalwood smoke notes,” and recommends patience (Best 2027–2042). Vinous (94 points, Nicolas Greinacher) calls it “a head-turner,” highlighting “ripe black fruits, melted licorice, garrigue and a touch of dried meat,” plus “a splash of menthol” and “a drive of acidity” powering a “long, complex finale.” Jeff Leve (95 points) describes a “deep, dark, concentrated” wine “loaded with sweet, dark berries, pepper, licorice, smoke, and herbs,” noting it “will benefit from a few years in the bottle” (2028–2040).
