Burgundy wine ( or ) is made in the Burgundy region of eastern France, in the valleys and slopes west of the Saône, a tributary of the Rhône. The most famous wines produced here, and those commonly referred to as "Burgundies," are dry red wines made from pinot noir grapes and white wines made from chardonnay grapes. Red and white wines are also made from other grape varieties, such as gamay and aligoté, respectively. Small amounts of rosé and sparkling wines are also produced in the region. Chardonnay-dominated Chablis and gamay-dominated Beaujolais are recognised as part of the Burgundy wine region, but wines from those subregions are usually referred to by their own names rather than as "Burgundy wines". Burgundy has a higher number of (AOCs) than any other French region, and is often seen as the most -conscious of the French wine regions. The various Burgundy AOCs are classified from carefully delineated vineyards down to more non-specific regional appellations. The practice of delineating vineyards by their in Burgundy goes back to medieval times, when various monasteries played a key role in developing the Burgundy wine industry. The historical importance of the Burgundy wine region and its unique climats system led to sites in the region being inscribed on the UNESCO World Heritage List as part of the Climats, terroirs of Burgundy site. Geography and climate The Burgundy region runs from Auxerre in the north to Mâcon in the south, or to Lyon if the Beaujolais area is included as part of Burgundy. Chablis, a white wine made from Chardonnay grapes, is produced in the area around Auxerre. Other smaller appellations near Chablis include Irancy, which produces red wines and Saint-Bris, which produces white wines from Sauvignon blanc. There are 100 Appellations in Burgundy and these are classified into four quality categories. These are Bourgogne, village, premier cru and grand cru. Eighty-five miles southeast of Chablis is the Côte d'Or, where Burgundy's most famous and most expensive wines originate, and where all Grand Cru vineyards of Burgundy (except for chablis grand cru) are situated. The Côte d'Or itself is split into two parts: the Côte de Nuits which starts just south of Dijon and runs till Corgoloin, a few kilometers south of the town of Nuits-Saint-Georges, and the Côte de Beaune which starts at Ladoix and ends at Dezize-les-Maranges.
