Research

The purpose of my program is to develop and extend knowledge that can be used to reduce production cost and improve the yield and quality of grapes used for raisin, table, or wine. We are on Facebook: http://www.facebook.com/viticulture, Twitter: http://www.twitter.com/grapetweets, and we write a blog: http://ucanr.org/blogs/Raisinramblings/
