On the Road in Sonoma County

Grape Day

Event Date

On The Road programs are educational seminars that help us to communicate with the California grape and wine industries by bringing faculty to different regions of California. The hope is that we are able to present relevant research being done at UC Davis and, at the same time, listen to the issues that are important to grape growing and winemaking professionals.
