SOUVIGNON BLANC

Managing 'Sauvignon Blanc' Vineyards

Operating a plot with this technical grape variety requires a rigorous technical approach. Developed by Russian research institutions (SKFNTSVV and Magarach Research Institute), the variety shows moderate vine vigor, which simplifies training, but demands strict protocols for maintenance and disease management.

Operational Performance and Crop Health

• Disease Protection: The variety exhibits moderate resistance to downy mildew. However, its susceptibility to powdery mildew and gray rot is significant. A consistent, high-frequency preventative spray schedule is non-negotiable to maintain a healthy canopy and cluster integrity.
• Yield and Management: Expect yields ranging from low to moderate. With small to medium clusters (up to 500g), the focus here is strictly on quality control. Careful crop thinning is essential to ensure the vines are not overtaxed and to maintain optimal sugar concentration.
• Maintenance Requirements: Moderate growth intensity makes pruning and canopy management efficient. However, the high vulnerability to rot means that air circulation must be prioritized throughout the season. Proper canopy architecture is key to mitigating the risks of humidity-driven infections.

'Sauvignon Blanc' is a classic choice for vintners dedicated to producing high-quality whites. It is not a low-maintenance crop; success depends on proactive monitoring and technical precision. For operators ready to invest in thorough phytosanitary care, this variety remains a reliable source of quality raw material for premium winemaking.
