The grapes come from three famous Premier Cru vineyards : Mont de Milieu, Montée de Tonnerre and Moireins. The pebbly soil derives from Jurassic (mainly Kimmeridgian) clays and limestones. Kimmeridgian is a layer that contains tiny fossil oysters. The soil is ideally suited to the Chardonnay grape, the only permitted variety for Chablis AOCs. At harvest time, the grapes are hand-picked, then carefully pressed. The juice ferments in barrels and stainless steel tanks. After seven-to-eight months of aging, the wine is bottled.
Instead of the Premier Cru I ordered, wine dot com sent me the plain Chablis, which is a lesser appellation wine and certainly not the same quality as a Premier Cru. The Premier Cru will say Premier Cru on the label, whereas the plain Chablis will merely say Chablis. (Duh!)The Premier Cru would sell for more than thirty dollors, so if wine dot come is still showing the Premier Cru at less than that price, they will probably ship you the plain Chablis instead of the Premier Cru. I have asked wine dot com to correct this error, but it does not look like they have done so as of today. (Gave this a third star because even though they sent me the plain Chablis instead of the Premier Cru, it was still pretty good. The plain Chablis had a clean fresh soap and mineral nose, and mineral and lemon taste. I bet the 1er Cru is really good.)
