(Reuters) - Despite a late harvest in the Sonoma region of California and heavy rains that tore through vineyards, California wine makers expect this year's grapes to yield superior wines. Like other grape growers in the region Saralee Kunde is coping with the impact of the delayed harvest because of the above average rainfall and cool summer weather. Her crop of Viognier grapes, a variety that originated in the northern Rhone region of France, is off by 60 percent.
