In contrast, the 2021 Châteauneuf Du Pape Roussanne Vieilles Vignes (100% Roussanne) is brought up in all new oak, and it has a normal pH of 3.7 and an alcohol of 14.5%. (In comparison, the classic white has a pH of 3.6 and slightly less alcohol at 14%.) Rich, full-bodied, and opulent, it has a gorgeous perfume of caramelized white peach, acacia flowers, toasted spices, and orange blossom. One of the most powerful, concentrated whites in the vintage, its oak is perfectly integrated, it's flawlessly balanced, and as I've written in the past, it's the Montrachet of the Southern Rhône!
