Heading south from Córdoba toward Malaga, you pass through hills ablaze with sunflowers in early summer, before reaching the Montilla-Morilés vineyards of the Córdoban campiña. Every fall, 47,000 acres' worth of Pedro Ximénez grapes are crushed here to produce the region's rich Montilla wines, which are similar to sherry. Recently, Montilla has started developing a young white wine similar to Portugal's Vinho Verde.
