In a series of video clips to be shown over the coming year we will explore the annual cycle of the vine at Quinta dos Malvedos, culminating in the vintage during September/October. This, the first of the videos, documents winter pruning.
Winter pruning (November – January)
Winter pruning of the vines is a crucial, almost entirely manual operation that marks the beginning of the viticultural year in the Douro. Normally starting during the second half of November, it can go on for up to three months and ideally should be 50% complete before the end of the year. Winter pruning of the vines is essential for their rejuvenation in the spring and because it is so labour-intensive and time-consuming, it accounts for around a third of our annual viticultural costs at Quinta dos Malvedos.
The process involves three separate stages. First, there is the pre-pruning, whereby the bulk of the redundant vine growth is removed with the use of cutters attached to small tractors. Next is the highly skilled manual task of pruning each vine, and removing the remaining tendrils caught in the trellis. Our pruners are equipped with electric secateurs, which increase productivity and make the task much less physically demanding. Finally comes the shredding of the spent canes lying on the ground. This plant fibre is then left to break down and adds much-needed organic matter to the rocky, schistous soil of Quinta dos Malvedos.
