The 2005 Domaine du Pegau Chateauneuf du Pape Cuvee Reservee is a red wine from the Southern Rhone region in France, specifically from the Chateauneuf du Pape appellation. This vintage is a proprietary blend, predominantly composed of approximately 80% Grenache, with the remainder being Syrah and Mourvedre. The wine is notable for its deep ruby/plum/garnet hue and 14% alcohol content, sealed with a traditional cork closure.

Jeff Leve from TheWineCellarInsider.com awarded this wine a score of 93, describing it as "dark in color, with a nose packed with pepper, garrigue, kirsch, black raspberry, licorice and kirsch." He emphasized its full-bodied and concentrated nature, highlighting its fresh and spicy character which fills the mouth with an array of flavors.

Robert Parker's Wine Advocate rated the 2005 Cuvee Reservee at 92 points, noting its deep ruby/plum/garnet hue and a nose full of "grilled meat juices, roasted Provencal herbs, tar, blackberries and black currants." The wine is characterized as medium to full-bodied, with firm tannins that suggest it needs additional cellaring of about 4-5 years and has the potential to age gracefully for two decades or more. Parker also commented on its resemblance to more austere vintages, like 1995.

Wine Spectator provided an excellent review, scoring the wine at 94 points. The review by JM described the wine as showing "gutsy blackberry and fig fruit up front, with notes of pepper, licorice, Turkish coffee and garrigue." The finish is notably long, with roasted herb and beef notes adding depth over time. The review also mentioned that while this vintage may not have the same range as 2003 and 2004, it possesses the intense grip characteristic of the 2005 vintage and has the potential to age well until 2028.

Jeb Dunnuck also gave high praise with a score of 95, observing that the wine's initial aromas of "bright raspberry, cherry and mineral" evolved with air to reveal "earthy, peppery and tar-laced" notes. He described the palate as "awesome with beautiful balance, tension and texture," leading into a long, tannic finish. Dunnuck noted the presence of subtle meat and leather aromas typical of Pegau wines, making the 2005 vintage outstanding.

Overall, the 2005 Domaine du Pegau Chateauneuf du Pape Cuvee Reservee is a well-regarded wine with a robust and complex profile, promising excellent aging potential and rich, evolving flavors.
