What is a major consequence of not pruning Tokay grapevines?

Not pruning Tokay grapevines can lead to reduced fruit quality. Pruning is a critical practice in viticulture that plays a significant role in controlling the vine's growth, managing its fruit production, and ensuring the health of the grapevines. Without proper pruning, grapevines can become overgrown, resulting in overcrowding of grapes on the clusters. This overcrowding can block sunlight and restrict air circulation, ultimately leading to issues such as inadequate ripening and increased susceptibility to mold or rot. These factors can detract from the overall quality of the fruit, affecting its taste, sugar content, and ultimately the wine that is produced from it.

In contrast, increased fruit yield, enhanced disease resistance, and improved growth control are typically associated with proper pruning techniques that support balanced growth and fruit development.
