The vineyards of Quinta da Carregosa extend across a schistous hillside of approximately 40 hectares. The farm's slopes benefit from a privileged sun exposure (south/east), rising to an altitude between 200 and 500 meters above sea level.

The knowledge of each plot of Quinta da Carregosa, knowing the excellent quality of the desired grapes, has led Manuel Costa and João Silva to implement, over the last few years, viticultural practices based on sustainability principles in integrated production methods, respecting and protecting the biodiversity and ecosystem of the estate.

Vinha do Reiro - Quinta da Carregosa has a vineyard with pre-phylloxera characteristics. It extends along small walls of stone extracted from the terrain, oriented according to the curves that support a row of vines with a very low plant density.

Vinha das Corigas - The post-phylloxera vineyard, located at the bottom of the slope, consists of wider terraces supported by stone walls. The vines are planted along the contour lines, making mechanization impossible. More than 15 different native Douro grape varieties are planted in this vineyard.

All viticultural work carried out in these old vineyards throughout the year is done manually, still using ancient viticultural techniques, such as soil tilling done with horses. Annual grape production is incredibly low, not exceeding 0.7 kg/vine.
