The grapes are grown in the Cape Agulhas wine region, where the sea breezes from the Atlantic Ocean create a cool microclimate. The winds blow directly off the ocean in both a south-easterly and south-westerly direction, providing consistent freshness throughout the summer and as a result, temperatures seldom reach above 30°C. This cool microclimate creates a slow ripening period, allowing the grapes to build flavour complexity and to produce naturally balanced wines. The diversity of soil types creates wines with great dimension and structure. A triple-wire vertical shoot system is used for trellising, which helps to provide optimum sunlight and airflow and protects the vines and shoots against the wind. Nature-friendly chemical sprays and copper treatments are used if necessary. Satellite technology is used to help determine optimal ripening; the grapes are then hand-harvested during the cool of the early morning.
