The 2017 Saint Peray Pur Blanc is sourced from 100-year-old Marsanne vines in the heart of Saint-Péray. While that may account for its appeal if you know what it is, I also loved this wine when tasted blind at the Maison des Vins in Tain l'Hermitage. Toasted marshmallow and melon notes provide a broad foundation, but they're reinforced and tightened by electric notes of white pepper, brine and citrus zest. Rich, long and intense, it should have a lifespan of a decade or more. Tasted twice, with consistent results.
