What vine training system is most appropriate for a high-vigor grape varietal in a warm climate, considering both yield management and fruit quality?

For a high-vigor grape varietal in a warm climate, a divided canopy training system like the Lyre or Geneva Double Curtain (GDC) is generally most appropriate to balance yield management and fruit quality. High-vigor varietals tend to produce excessive vegetative growth, leading to shaded canopies and reduced fruit ripening. Divided canopy systems address this by splitting the vine's canopy into two separate curtains, increasing sunlight exposure and air circulation around the fruit zone. This improved light penetration enha....
