In hot Argentine vineyards, what is a key canopy-management goal?

In hot climates, a key canopy-management aim is to moderate the fruit’s exposure to sun and heat to protect berries and promote even ripening. Shading the clusters during peak sun helps prevent sunburn and keeps the ripening process balanced, avoiding overly rapid sugar accumulation and flavor shifts. This approach preserves acidity and color while reducing heat stress, leading to better fruit quality. That’s why protecting fruit from sunburn and balancing ripening through shade is the best choice. Removing all leaves after veraison would remove the protective shade entirely and increase sunburn risk; maximizing leaf area would raise heat and sun exposure; pruning aggressively to increase yield doesn’t address protecting the fruit from sun and balancing ripening.
