Wine Spectator reports favorably on the 2015 vintage in the Northern Rhône, saying: "'"We had no disease pressure; it was a healthy and particularly rich vintage," said Michel Chapoutier, whose Tain-based estate produces wines from every Northern Rhône appellation. "Although we identified some hydric stress in a few areas, the little rains of the 24th of August and 1st of September enabled [the vines] to unblock everything and end up with a very interesting sugar/acidity balance. Thus it was important not to rely on degrees and analysis this year, to avoid rushing to harvest and get unbalanced wines." Chapoutier believes that wines from granitic soils are concentrated, but not so much that they hide the signature style of that terroir. And wines from more sedimentary soils show finesse, despite ripe alcohol levels."
