Situated within the valley's interior, the vineyard benefits from a rich tapestry of diverse terroirs and microclimates. Each parcel features unique exposures tempered by coastal breezes, which intricately craft complexity in the resulting wines. The vineyards
are planted across 12 small valleys, totalling 327 hectares. More than 6,000 soil analyses were conducted to match the clonal selection of rootstock and varieties. The soil types include colluvial, alluvial, sand, clay, and gravel stone, each imparting a
distinctive characteristic to the resulting blend. Milla Calla incorporates all the varieties on the estate. The vines are planted in the Colchaguilla, La Feria, and Boqueron plots at a high density of 10,000 vines per hectare, with six bunches per vine. 50% of the vineyards are massale selection, and 50% are from carefully selected clones. The vines are sustainably cultivated and hand-harvested at optimum maturity.
