Chablis is one of the most endangered vineyards in the world: winemakers have to deal with these spring events until mid-May, which can cause irreversible damage when buds burst. The methods put in place to protect themselves, such as the vines spraying, for example, have strongly contributed to the vineyard maintenance.
Located south of the Paris Basin on a geological depression dating from the Upper Jurassic (- 150 million years), the Chablis vineyard has a clay-limestone soil containing fossilized shells, called "Kimmeridgian limestone". All the Grand Cru and Premier cru parcels of Chablis are established on these lands.
A good wine of Chablis is tight and nervous, it reveals flint flavors typical of its terroir, whose intensity varies depending on its "Premier Cru" or "Grand Cru" quality.
