(Wines&Vines) - For Scott Williams, vineyard manager at Pacific Vineyard Co. in the Edna Valley, 2010 was the most difficult growing season he’d ever encountered—that is, until 2011 rolled around. “Our fruit set was pretty compromised, and it just seemed like everything was going wrong,” Williams told an audience of grapegrowers gathered at the Sustainable Ag Expo held this week at the Paso Robles Event Center. “When I say we finished harvest last Thursday, that’s about the happiest thing that’s happened in a year and a half.”
