ASEV-NGRA Precision Viticulture Symposium


Register Today!  

The American Society for Enology and Viticulture (ASEV) and the National Grape Research Alliance (NGRA) each work to support research for the U.S. grape and wine industry. ASEV is a professional society of enologists, viticulturists and scientists in the fields of wine and grape research and production, and NGRA is an industry coalition representing the research priorities of wine, juice, raisin and table grapes nationwide.

In 2021, we’re partnering to produce the ASEV-NGRA Precision Viticulture Symposium, held virtually on Monday, June 21, 2021. We’ve gathered some of the most highly regarded scientists working in precision viticulture research and the well-regarded growers applying precision technology and techniques for a non-commercial exploration of the current and future state of precision viticulture.

The event will help growers understand and adopt the research advance in data-driven farming. And it will give scientists a forum, too, to gain valuable insight from fellow researchers and from industry early-adopters who share their experiences. In short, this symposium seeks to provide two-way dialogue to identify current research gaps, inform future scientific discovery and inspire application of current innovations.
