The Schlossberg vineyard in Alsace, designated Grand Cru, is a steep, terraced property on granitic soil farmed by the Blanck family on blancksustainable standards. The Paul Blanck Schlossberg Riesling Grand Cru 2012, Alsace, was fermented by natural yeasts in stainless steel and rested for a year in large wooden foudres, followed by two or three years in bottle before release. Have mercy, what a lovely wine! The color is pure medium gold; seamlessly woven aromas of quince and ginger, peach and lychee, green tea and lemongrass open to notes of lightly spiced pineapple and grapefruit and hints of jasmine and honeysuckle. Crystalline acidity chimes a course through a texture that’s part swooningly ripe, part school-teacher astringent, for an effect that’s vibrantly balanced and exciting; flavors of roasted lemon and lemon balm are spicy and savory, dry and refreshing, bolstered by a burgeoning coastline of saline limestone and flint minerality and a finish that trades in lime peel and a note of grapefruit rind bitterness. For a riesling of such depth and complexity, it’s remarkably clean, bright and light on its feet. 13 percent alcohol. Now through 2022 to ’25, giving the wine a chance to mellow and burnish. Excellent. About $34.
