There are few wine regions in the world with a reputation as glowing and well established as that of the Bordeaux, in France. Situated mainly around the Dordogne and Gironde rivers, Bordeaux makes the most of its humid climate and rich, clay and gravel based soils to grow some of the finest examples of red and white grape varietals on earth. Wineries in this region have been in operation for hundreds of years, and have carefully developed the expertise required for the production of carefully balanced and utterly delicious blended red and white wines, alongside some exceptional single variety bottles. Many of the chateaux found in Bordeaux have become household names, due to their prestige and the excellence of their products, grown with love and dedication by heritage wineries in this beautiful and special region. France is widely known as being the home of many of the world's finest white wines, and within France, the name which rings out across the wine world and is always associated with excellence of quality and flavor is Bordeaux. The white wines of the magnificent Bordeaux region are typically blended, and rely on the winemaker's skill and expertise to achieve the fine balance between the primary grape varietals used. Most blended white Bordeaux wines are made up of Sauvignon Blanc, Sémillon and Muscadelle varietals, although there are actually nine grapes officially allowed by French wine law for the inclusion in Bordeaux white wines. The other six are Sauvignon Gris, Merlot Blanc, Ugni Blanc, Colombard, Ondenc and Mauzac, although the use of these other grapes has been in steady decline over the past century.
