I think a success in the vintage, the 2013 Chateauneuf du Pape les Trois Source comes from the same terroir as the Reserve cuvee and is 60 Grenache, 15 Cinsault, 15 Syrah and 10 Mourvdre. It reveals pretty black and blue fruits, leafy herbs, violets and some Pinot Noir-like forest floor characteristic, as well as medium-bodied depth and an elegant, silky texture. It's not a blockbuster, but it's nicely balanced and has sound underlying structure, all suggesting it will have 10-12 years of longevity.

Well-built, with a slightly chunky frame that should settle in soon enough, as the core of dark currant, plum and raspberry paste flavors have ample depth. Dried anise, sweet tobacco and warm ganache notes fill in through the finish. Fresh acidity lends support, giving this a sense of elegance despite the heft.
