The "terroir" across Côtes de Gascogne changes moving east to west with the eastern region more maritime from proximity to the Atlantic Ocean and changing to a continental climate moving inland. According to wine-searcher,com, "In the east, summers are warmer and drier, and the clay-limestone soils retain water more effectively. Nearer the coast, loose, sandy soils with good drainage and high rainfall characterize the vineyards".
White wine grapes dominate the region with over 90% of planting, but for the lesser-grown red wine grapes, Tannat is a major player. The grape is thought to have originated in the rugged Basque regions between France and Spain which may explain its inherently tough vines, thick leaves, and resistance to diseases. In general, Tannat grapes contain high natural acidity and aggressive tannins leading to wines that age nicely. Tannat wines are also characterized by deep color and high alcohol.
