Growers now are monitoring vine stress and ensuring that they’re getting enough, but not too much, water.
In the next few weeks vineyards may undergo a "green cluster harvest." This is a thinning process to scale back the volume of fruit per vine to enhance flavors and character of the remaining fruit.
Pinot Noir and Chardonnay are the primary grapes being harvested on the valley floor. Usually, this is fruit that will make the great sparkling wines of the Napa Valley. Since sparkling wine is fermented twice, winemakers are looking for grapes with low sugars and high acids.
