Dormancy in the vineyard is time for the vines to rest. Dormancy protects the vines from the winter cold and frost. It is this period that the vines are pruned. Pruning determines the crop level or amount of fruit the vineyard will produce the following year. Here at Hamilton Oaks Vineyard we try to balance the vine with the amount of fruit each one will produce during this period. This will be done by pruning.
Note how the vines appear during the dormancy period before they are pruned and after pruning. Our vines are pruned to produce between 2-3 tons/acre. By reducing the yield, we are able to produce a grape with intense varietal characteristics. So dormancy lasts from November thru March. They have lost all their leaves and become barren and woody. We normally prune our vines in January, before they start to bud.
