A succession of superb vintages from 2015 to 2017 has produced some of the best red wines in recent decades throughout the southern and northern Rhône. Winemakers and critics will be debating for years which vintage reigned supreme. Meanwhile, for consumers, it’s simply an unmissable opportunity to drink up. The 2015 vintage will be remembered for its power and structure. The Grenache-based wines of the south are intensely ripe and concentrated, while even in the north—where Syrah is known for its elegance and cutting acidity—the reds are uncharacteristically hedonistic. In both cases, cellaring before opening is recommended, as massive tannins make these wines exceptionally ageworthy and almost unapproachable when young. The 2016 vintage was marked by ripeness and intensity calibrated by freshness and detail. In the south, wines are ripe and deeply concentrated but keenly balanced by minerality, acidic cut and structured tannins. In the north, a cooler and more classic vintage produced wines with exceptional fruit purity and sleeker tannins. Winemakers and critics will be debating for years which vintage reigned supreme. Reds from the 2017 vintage are just hitting the market, but are already exhibiting a fantastic mix of concentration and elegance. Here’s the bad news: Maladies like frost, hail and mildew devastated yields in the southern Rhône in 2017. Prices have undoubtedly crept upwards for iconic appellations like Châteauneuf-du-Pape and Gigondas. However, excellent value can still be found in the crus of Vacqueyras, Rasteau and Lirac. Treasures also abound in regional bottlings of Côtes-du-Rhône Villages and underappreciated appellations like Costières de Nîmes and Luberon. Recent yields in the north have been healthier than the south, but the north produces less than 5% of all Rhône Valley wines by quantity. In recent years, prices for Côte-Rôtie, Hermitage and Cornas have all risen. Remarkable values are still found from less expensive appellations like Crozes-Hermitage and Saint-Joseph.
