Current Wine and Winegrape Research

Competitive grants have funded some of the most exciting new and broad-reaching research on issues relating to wine grapes and enology. A full day of brief presentations by researchers describing their projects, which were cooperatively funded by one or more of the agencies described below, will be offered in this unique forum.

This is an opportunity to hear and discuss the latest research directly from these highly-regarded researchers. Topics include work on grapevine breeding and evaluation, cultural practices, disease and insect pest control, and enology. The format of 20-minute reports allows for synopses of many projects in a single day. Each scientist will have 15 minutes to speak and an additional five minutes to answer questions from the audience.

The researchers competed successfully for grants from the American Vineyard Foundation, a nonprofit corporation supporting research in viticulture and enology; federal funding through the Viticulture Consortium West (VCW); and/or state funding through the California Competitive Grants Program for Research in Viticulture and Enology. To qualify for these grants, researchers must submit yearly grant proposals and reports, undergoing continuous scrutiny of their work from peer review panels.
