Schramsberg Vineyards, Calistoga
Calistoga , California
Concierge.com's insider take:
Napa and Sonoma have few fine sparkling-wine producers. Though some (such as Jordan in Sonoma and Domaine Chandon in Napa) are exceptional, nothing compares to Schramsberg, the first sparkling-wine producer in California to use traditional Champagne techniques and varietals. Served at the White House since 1972, Schramsberg's chardonnay-based blanc de blancs is this Napa Valley winery's signature. To sample it, you must take the tour, which includes fascinating historical details about the valley as well as a walk through caves dug 150 years ago by Chinese laborers (bring a sweater; the caves are chilly). Unlike at other sparkling-wine cellars, you'll not only sample the signature wine and a few low-end vintages, you'll also get to taste the entire flight of têtes de cuvées. Call at least a month in advance during high season. Tasting fee; appointment required.
Open daily 10 am to 2:30 pm.
