A shade behind the spectacular 2016, the 2015 Cairanne Blanc Haut Coustias is still a terrific wine. It shows more toasty, nutty notes on the nose, making it less aromatic and open, but it remains rich, spicy and long, with hints of pineapple, melon and citrus. It's a blend of Clairette, Grenache Blanc, Roussanne and Marsanne that was matured in a variety of different vessels, then blended together prior to bottling.
