The 2019 Domaine de Saint-Prefert Chateauneuf du Pape Collection Charles Giraud is a proprietary blend from the renowned Rhone region of France. This wine is composed of 60% Grenache and 40% Mourvèdre, partially destemmed and aged in demi-muids, resulting in a robust 15% alcohol by volume. The wine's deep ruby/plum color sets the stage for an array of complex flavors and aromas.

Jeb Dunnuck awarded this wine an impressive 99 points, describing it as "a rich, savory, complex bouquet of black raspberries, cassis, toasted spice, cured meats, and graphite." He notes that the Mourvèdre component particularly stands out, making the wine "full-bodied, concentrated, and structured, yet never losing its seamless, flawlessly balanced profile." Dunnuck recommends cellaring the wine for 4-5 years to reach its full potential and suggests it will have a longevity of 20-25 years.

Decanter also praised the wine with a 96-point score, highlighting its "vibrant nose" and "amazing vibrancy of fruit." The review notes the influence of 80-year-old vines grown on galets roulés over blue clay, contributing to the wine's "deep-set vein of salinity that accentuates the freshness." According to Decanter, the wine finishes "long and vibrant, like a peacock's tail."

Vinous, with a 97-point score, described the wine as "opaque ruby" with a "complex, expansive bouquet" that includes "ripe red/blue fruits, exotic spices, and potpourri." The wine displays "concentrated black raspberry, boysenberry, violet pastille, and fruitcake flavors" and concludes with an "insanely long, penetrating finish shaped by emerging, polished tannins."

Wine Spectator matched the 97-point score, noting the wine's "large scale" and "seamlessly layered" flavors of "cassis, red tea, crushed plum, warmed cherry compote, Turkish coffee, melted red licorice, and warm earth." The review emphasizes the wine’s "lush, yet focused finish."

Jeff Leve also gave the wine 99 points, appreciating the "cool, peppery, meaty, full-bodied quality" imparted by the Mourvèdre. He describes the wine as "dark, deep, opulent and rich, as well as balanced, refined, elegant and plush." Leve suggests allowing the wine to age for at least 5 years for further development and enjoying it over the next two decades.

Robert Parker's Wine Advocate awarded 96 points, noting the wine's "tremendous richness and depth" with flavors of "blueberries, black cherries, and plums, plus some more savory suggestions of black olives." The review highlights the wine's "long, dark, earthy finish and plenty of tannin," recommending serious cellar time.

Overall, the 2019 Domaine de Saint-Prefert Chateauneuf du Pape Collection Charles Giraud is a highly acclaimed wine with a rich, complex profile and excellent aging potential.
