What is a key advantage of cordon-pruned vines with either spurs or short canes?

A key advantage of cordon-pruned vines with either spurs or short canes is the balanced distribution of the crop. This pruning method helps to maintain an even canopy and encourages the production of fruit buds in a balanced manner along the cordon. As a result, the vines can yield a consistent and manageable crop load which is vital for achieving high-quality fruit and ensuring that each cluster gets adequate sunlight and airflow. This balanced distribution ultimately improves the overall health of the vine and enhances the quality of the grapes produced, leading to better wine outcomes.

Other options may highlight different benefits but do not directly relate to the primary functional advantage of this pruning method. For example, while aesthetics may be a consideration, it is not the main purpose of cordon pruning. Similarly, growth rate and resistance to wind damage are influenced by multiple factors including variety and growing conditions, but are not directly improved solely by the choice of cordon pruning with spurs or short canes.
