Think Napa Valley, and most wine lovers think Cabernet Sauvignon and Chardonnay. Indeed, the Napa Valley is a single appellation, or AVA (American Viticultural Area). Yet within its borders reside 16 sub-appellations, each with its own distinctive microclimate, and often, its own signature grapes.
The St. Helena AVA, for example, home to the Rutherford Wine Company and many others on the celebrated Silverado Trail, is a warm area with less fog or wind than many more southern areas, making it perfect for a rainbow of varieties such as Cabernet Sauvignon, Cabernet Franc, Merlot, Syrah, Zinfandel, Sauvignon Blanc, and Viognier. Another estate that capitalizes on the variations of Napa Valley terroir is the Fleury Estate Winery, which has three vineyards in three appellations at three elevations.
Many wineries here have deep roots as pioneer vineyards, showcasing Napa Valley’s longstanding commitment to premium grapes. Just a few examples: Mayacamas Vineyards is comprised of a stone building, which in 1889 was carved into the side of a dormant volcano crater on Mount Veeder (happily, that historic building survived the 2017 wine country wildfires). Sinegal Estate was once a St. Helena Pony Express stop, then the historic Inglewood Estate, before being bought and completely renovated by new owners in 2015. Beaulieu Vineyards, founded in 1900 and housed in a building that dates to 1885, managed to flourish during Prohibition, when so many Napa vineyards were forced to shutter, due to their contract to provide sacramental wines to the Catholic Church. And some wineries have brought their own sense of history: Calistoga’s Castello di Amorosa, owned by Dario Sattui, makes Italian-inspired reds in a sprawling, 13th-century-style castle.
A new generation of wine growers is planting newer-to-the-area varieties as well. Summers Estate Wines in the Calistoga AVA bottles Charbono, a rare Italian grape found on less than 100 acres in all of California, plus a Greek Muscat Canelli known in Europe as Muscat Blanc à Petits Grains. Plush, plummy Merlot is back in the spotlight too, such as Duckhorn Vineyard’s prized bottling from the Atlas Peak AVA.
