Chablis is a very northern and the most significant wine region in Burgundy. Grand Cru vineyard is famous for its soil-Kimmeridgian marl (limestone and clay layered with tons of oyster fossils). All planted with Chardonnay. Kimmeridgian soil occurred around 150-157 million years ago.
The hillsides of Grand Cru vineyard are hand-harvested. Chablis lover needs to be patient and wait at least a year after the wines were released to enjoy elegant yet powerful white wine with flavors of lemon, oyster shells, and hazelnut.
