What does proper training of grapevines establish?

Proper training of grapevines establishes a strong framework for future growth by guiding the vine's development in a way that promotes health and productivity. This process involves choosing the appropriate support systems, such as trellises, and carefully managing the position and direction of the vine shoots as they grow. By creating an appropriate structure, the vines can achieve better sunlight exposure, airflow, and access to nutrients, which collectively improve fruit quality and yield. A well-trained vine also facilitates easier maintenance and harvesting, significantly impacting the long-term sustainability and profitability of the vineyard.
