Napa Valley Vintners Commit $2.5 Million to Combat Red Blotch Virus

The Grapevine Red Blotch Virus Research Initiative aims to bridge the gap between academic discovery and vineyard application. Over the next three years, the program will fund competitive research focused on early diagnostic tools, virus transmission patterns, and practical mitigation strategies. The initiative, which grew out of 2025 planning sessions led by the Moët Hennessy Robert-Jean de Vogüé Research Center, seeks to standardize nursery testing and ensure the availability of clean planting material.

Governance of the program rests with a 10-member committee split equally between industry leaders and scientific experts. Projects will undergo rigorous evaluation by an independent Technical Review Panel to ensure feasibility and measurable impact. Notable contributors include Dominus Estate, Darioush Winery, Joseph Phelps Vineyards, and Opus One Winery. The American Vineyard Foundation will serve as the fiscal agent, with the first round of research proposals scheduled to open in January 2027.
