The Coteaux du Giennois in the upper Loire zone shares the famous limestone and silex soils that make the great vineyards of Sancerre and Pouilly-Fume famous. The Berthier brothers’ 2014 Coteaux du Giennois could be likened to a “baby” Pouilly-Fume, as it offers similarly brilliant notes of gooseberry, grapefruit, flint, mint, white pepper and freshly cut grass. Lemony acidity, notes of lime zest and fresh ginger enliven the wine on the palate, while electric waves of limestone and silex minerals inform you that this wine could have come from nowhere but the natural home of Sauvignon Blanc: the eastern Loire Valley. Pair this beauty now and over the coming two years with sauteed green vegetables, fresh oysters, clams, mussels and freshwater fishes with a beurre blanc sauce, or as a revivifying aperitif after a hard day’s work. Stunning Sauvignon Blanc!
