Napa Valley sparkling wine producer, Mumm Cuvee Napa, inaugurated the first harvest of the new millennium last week when it brought in 140 tons of grapes -- including the new Dijon clones of Pinot Noir from Yountville -- that were pressed at the Rutherford-based winery. Traditionally, after the winery picks grapes from vineyards in Yountville, pickers move to mid-Napa Valley before moving southwest to Carneros to finish harvesting.
