(PressDemocrat) - As the sun rose over Atlas Peak early Friday, speckling golden light on misty grapevines in Oakville, a crew of 30 pickers hustled ripe clusters of pinot noir grapes off the vine. The clusters were nimbly cut free and gingerly dropped into bins headed up the Silverado Trail for Mumm Napa, in the first reported grape harvest of the year on California's North Coast. “The action is on,” said Alex Vyborny, owner of Vyborny Vineyard Management, which manages 1,000 acres of vineyards throughout Napa, Sonoma and Mendocino Counties. “The quality should be really good. We've had great weather.”
