Robert Parker's Wine advocate (97 points):
"A blend of 60% Grenache aged in concrete and 40% Mourvèdre aged in new barriques, the 2015 Chateauneuf du Pape Deus Ex Machina is a modern-day monster. This is rich and powerfully concentrated, loaded with scents of vanilla and baking spices, yet it also possesses masses of red fruit (raspberries, cherries and plums), a wonderfully creamy and intense mid-palate and a long finish."

"One of the gems of the vintage is the 2015 Châteauneuf-du-Pape Deus Ex Machina which is as always, a 60/40 split of Grenache and Mourvèdre. It offers sensational notes of blackberries, ground herbs, white chocolate and an undeniable meatiness (It reminds me of a butcher shop from the south of France) that develops with time in the glass. Full-bodied, perfumed, complex, elegant and layered, it doesn’t have the density of the 2015, 2010 or 2007, yet is seamless. Give bottles 4-5 years and enjoy over the following 15+."
