Mumm Napa
When Champagne Mumm of France set about establishing a California sparkling-wine outpost, its winemaker chose the Napa Valley, where today the winery sources grapes from more than 50 local producers. Made in the méthode traditionnelle style from Chardonnay, Pinot Noir, Pinot Meunier, and occasionally Pinot Gris, the wines are all fermented in the bottle. Most guests enjoy them alfresco, by the glass or flight, on two patios with vineyard views. Small-batch cuvées are served with artisanal cheeses under the sprawling branches of a nearly-two-centuries-old blue oak.
