LIGNORELLES, France (AP) — On a brisk late September morning in the heart of Chablis wine country, grape pickers haul large and heavy buckets over their shoulders, drenched in sweat as they climb the very steep slope of the Vau de Vey vineyard. It’s the final day of the harvest at the Domaine Roland Lavantureux winery, and workers are handpicking the last of the prized Chardonnay grapes that will eventually be transformed into the bright and high-end Premier Cru that is bottled by the estate.
