How does excessive vine vigor affect Tokay grape production?

Excessive vine vigor can significantly impact Tokay grape production by reducing fruit quality and yield. When a grapevine exhibits excessive vigor, it allocates more energy and resources toward leaf and shoot production rather than fruit development. This can lead to overcrowding of foliage, resulting in poor light penetration to the fruit clusters. As a consequence, the grapes may develop uneven ripening and potentially lower sugar concentrations, affecting the overall flavor profile of the wines produced from these grapes. Additionally, the increased leaf area can lead to higher moisture retention around the fruit, creating conditions that are more conducive to disease, further compromising both yield and quality.

The management of vine vigor is crucial in viticulture to ensure a balance between vegetative growth and fruit production. This balance is essential for achieving optimal conditions for both quantity and quality of grape harvests.
