The 2015 Cote Rotie La Mouline contains the most Viognier of any of Guigal's La Las: 11%. That tends to make it more open and approachable when young, but the 2015 seemed closed at the time of my visit. Cedar and vanilla frame mixed berries in a full-bodied, plush wine that somehow never seems heavy. It shows great elegance and length, and I'm confident the complexity it showed at earlier tastings will reemerge with a few years in the bottle.
