The imposing châteaux -the typical wineries in Bordeaux- are the hallmark of the region, literally wine-producing castles. There are over 6,000 of these distinguished Bordeaux wine châteaux along the Wine Route in the region and most of them can be visited on a Bordeaux wine tour. This tour of their vineyards and cellars will reveal secrets of some of the most famous wines in the world, including the Grands Crus Classés of 1855.
