The Don Maximiano vineyard is located in the Aconcagua Valley and the oldest among them are Max I, Max II and Max V blocks. The region has a long dry season with moderately warm summer days cooled by the soft evening breezes that enter the valley from the Pacific Ocean. Cabernet Sauvignon and Carmenere vines were planted in 1978 and 1993, respectively, while the Petit Verdot was planted in 1999. The three vineyard blocks that contribute grapes for Don Maximiano Founder’s Reserve are planted on north or northeast facing hillsides with 5°–25° of slope. Soils are volcanic, colluvial and piedmont (Max I and II) or alluvial (Max V) in origin, with good drainage conferring low to moderate vigour. The colluvial and volcanic rocky soils of Max I show high presence of mica with clay-silt texture. Max II has deep colluvial soils of volcanic origin, with loam to sandy-loam texture, and both have 30–40% stone content. Max V has deep gravelly alluvial soils with 50% stone content and excellent drainage.
