Unlike the Bordeaux region, Burgundy is a unique conglomeration of thousands of small growers and individual wine makers. Producing both red and white wines, the main grape varieties in the region are Pinot Noir and Chardonnay. Aside from Chateau wine makers, individuals who buy grapes and finished wines for blending and bottling under their own label, known as négociants, are a vital contribution to the prestige of the region. A few hundred miles northeast to Bordeaux, the area's climate is hot and humid during the summer and cold in the winter. The Burgundy region is divided into the more distinct regions of Chablis, The Côte de Nuits, The Côte de Beaune, The Côte Chalonnaise, The Mâconnais, and sometimes Beaujolais. AC regulations rank Burgundy wines from the best in quality, the Grand Crux, to the general label that appears on all Burgundy wines not suitable for other rankings, the AC Bourgogne. Larger house négociants are usually reliable and include wines such as Jadot, Drouhin, Bouchard, Louis Latour and Faiveley.
