The grapes are going through version this week. This is when the grapes begin to change color as they ripen. The sugar inside them will now begin to increase as the acid slowly drops. We’ll be monitoring this as the weeks go on until they reach the optimal point and that’s when we harvest. We also begin to leaf-pull at this stage, which is where we remove the leaves in the fruiting zone to encourage more airflow around the clusters. This will help keep them dry and lessen the likelihood of mildews.
