92 Points: Robert Parker's Wine Advocate
"As to the reds, all of these show beautiful purity of fruit and impeccably made profiles. As a whole, 2015 was consistent throughout the Southern Rhône, and you see that consistency in this lineup.
Named after Michel’s father, the 2015 Côtes du Rhône Guy Louis is always a first rate Côtes du Rhône and the grapes come mostly from the Cru appellations of the Southern Rhône. A blend of 60% Grenache, 30% Syrah and 10% Mourvèdre, mostly destemmed, it has lots of jammy black cherry and black raspberry notes, ample garrigue and spice, medium to full-bodied richness and fine, elegant tannin that emerge on the finish. It’s a serious, classy Côtes du Rhône that will drink nicely through 2025."
