(KGO) -- Napa Valley grape growers are starting the harvest as they try to beat the rain. The picking is going on day and night in the valley and so far, the weather has been just what the vineyards ordered. Hang around long enough in a place like the tasting room at the Napa Valley's Plump Jack Winery and it feels as if all the world's connoisseurs pass through. On Wednesday, they found an extra visual bonus -- the first sauvignon grapes from this year's crop. It's a wine maker's delight, with most still on the vines.
