The Loire Valley can be grouped into Central Vineyards, Touraine, Anjoy-Saumur and Nantais, each subject to different climatic influences. The spread ranges from the continental centre to the more Atlantic-influenced, semi-continental and the oceanic breezes on the Atlantic coast.
The region lies at the northern limit for the production of Sauvignon Blanc, Chenin Blanc, Melon Blanc and Cabernet Franc.
The region's trade and history are intrinsically linked to the 600-mile-long Loire River.
