The Unified Symposium, one of North America's largest trade and wine industry seminars, returns Jan. 29 through 31 at the Sacramento Convention Center.

Beginning in 1995, two wine industry organizations, the American Society for Enology and Viticulture (ASEV) and the California Association of Wine Grape Growers (CAWG), joined efforts to present Unified in order to highlight issues and trends in the wine industry.

Wine Business Monthly and its online version, winebusiness.com, are major sponsors.

All seminar details, costs — per day or per session — and information about lodging can be found at the main web site, unifiedsymposium.org

Registration opens at 1 p.m. Monday, Jan. 28, and the conference opens at 9 a.m. Tuesday, Jan. 29 with a general session entitled "How the Global Wine Market Affects U.S. Production."

While online registration closes Jan. 22, attendees can still register onsite during the event itself, organizers emphasized.

The trade show portion of Unified opens at 9 a.m. Wednesday and continues until 6 p.m., and again from 9 a.m. to 4 p.m. Thursday.
