Largest Wine & Grape industry trade show in North America. January 28th - 29th, 2026 - SAFE Credit Union Convention Center, Sacramento, CA

Since the American Society for Enology and Viticulture (ASEV) and the California Association of Winegrape Growers (CAWG) joined forces to create the Unified Wine & Grape Symposium in 1995, it has become the largest wine and grape conference in the nation. And while we’re proud of the size of the Unified Symposium, it is our established reputation for providing outstanding, current and breaking news, as well as information and content that we find most rewarding. As one of the industry’s premier gatherings, the Unified Symposium presents a vital platform to focus on the issues shaping today, while interfacing the topics and trends shaping the future of grape growing and winemaking.
