The village of Chignin is among Savoie’s top crus, and this family-run domaine—now headed by Guillaume Quenard, the fourth successive generation to tackle these daunting slopes—has a history of doing this terroir justice. Jacquère takes on an intensely mineral expression in these “soils” of lime-stone scree—rocks that have broken off the mountain over tens of thousands of years of erosion. This is particularly true of this cuvée from seventy-year-old vines that have set their roots deep into this stony pile of rubble. The nose is delightfully fruity with nectarine, peach, and citrus, along with a talc-like dusting of minerals. On the palate, you’ll find the same succulent fruit backed by bright acidity and a cool-climate snappiness as pure as melted snow. Few things are more satisfying as an apéritif than a chilled glass of this Alpine elixir.
