Climate Change Symposium: Part 1 Viticulture
This symposium will provide a comprehensive review of how climate change impacts the grape and wine industry. Topics will include three primary areas of interest, including a review of the changing conditions, the physiology behind plant response to environmental stresses of climate change, and the impacts of breeding programs designed to address production challenges that come with climate change. Presentations will address the concerns for viticulture in both cool, warm, dry and humid areas of the world. Scientists from across the US and internationally will provide a balance of theoretical and applied research. Please join us for a one-day symposium on viticulture in 2022 with a follow-up symposium on enology impacts in 2023.
Organized by ASEV Technical Program Committee
