On Quinta do Zambujeiro, we use a mix of conventional and biological farming practices. We do not use any herbicides and protect our soils with natural cover crops over the wet winter season. The goal is to preserve and protect the beautiful nature and terroir of the estate. The base of our wines is the vineyard. Our skilled workers treat every vine with great care. Without the hard work in sometimes-harsh weather conditions, we could not produce these great wines. We strongly believe that only vineyards with low yields can produce wines with high concentration in flavor and taste, made for a long life in the bottle. We reduce all our vineyards in yield. The average harvest is 23 hl per hectare.
