A record cold snap in Mendocino County over the weekend caused little damage to wine grapes but chilled the hearts of farmers who already have suffered huge losses this year. "It's just one more thing on top of one more thing. You kind of hold your breath," said Potter Valley wine grape grower Pauli. Temperatures dropped to 31 degrees in the Ukiah Valley on Saturday night and early morning, the coldest Oct. 12 morning since record keeping began in Ukiah in , said Nicolini, a meteorologist with the National Weather Service in Eureka. The previous record was 34 degrees in. Temperatures were milder in Sonoma County, and there were no reports of related problems, county officials said. Farmers in Redwood Valley and other cooler regions in Mendocino County reported temperatures as low as 27 degrees. An estimated 30 percent to 50 percent of that county's wine grape crop had yet to be harvested when the hit, the tops of unprotected vines and effectively freezing the ripening process. Most unprotected wine grape crops already had adequate sugar content, so they were unharmed, said Mendocino County Agricultural Commissioner Bengston.
