Please join the Lodi Winegrape Commission on Tuesday, February 1st for the 70th Annual Lodi Grape Day celebration! Lodi Grape Day is hosted by University of California Cooperative Extension (UCCE) and the Lodi Chamber of Commerce’s Agribusiness Committee. The agenda with the full list of speakers has just been released (please see below).

For 70 years, the Agribusiness Committee of the Lodi District Chamber of Commerce, along with University of California Cooperative Extension, has brought information about improving yields, fighting diseases, market trends, and mechanization technologies to the hundreds of growers who attend Lodi Grape Day. After learning about relevant viticulture topics in the morning, growers, pest control advisors, winery personnel, bankers, and business leaders gather together for a special luncheon featuring a keynote speaker. This year’s keynote speaker is Honore Comfort, Vice President, International Marketing at the Wine Institute. Attendance during the morning presentations and wine tasting is FREE and open to everyone (no tickets or RSVP required). Tickets are required for the luncheon and keynote speaker presentation.
