Chablis is a French wine that is traditionally produced by vineyards located in the northern region of Burgundy, though in the twentieth century the name became a generic appellation in the United States for many ordinary white wines produced in various other parts of the world. Made from chardonnay grapes, Chablis is usually described as flinty, full-bodied, and dry. In the Chablis region of France, the soil the grapes are grown in is believed to have a tremendous impact on the wine they are used to make. The vineyards there are, therefore, classified by a number of categories in order to differentiate between the kinds of wines that they characteristically produce. Those described as Chablis Grand Cru, which are found along the north bank of the Serein River, are regarded as the best vineyards, and the wines they generate generally command the highest prices.
