Winemaker Notes
Native to Southwest France, Valdiguié also maintains a fairly substantial history in California. Given its high-yielding capacity, Valdiguié became very popular during the Prohibition. Until 1980, Californians called it Napa Gamay because of its similarities to Gamay as a finished wine. But in that year, a French ampelographer, Pierre Galet correctly identified it as Valdiguié—not Gamay. Today it still grows in pockets of respected appellations throughout the state. Somm Secret—In France it is also called Gros Auxerrois.
One of Napa Valley’s oldest wine growing subregions but last to gain appellation status, Calistoga occupies the northernmost section of the valley. Beginning at the foot of Mount St. Helena, its vineyards stretch over steep canyons and roll out onto the valley floor. The soils in Calistoga are volcanic, which means they are heavy in minerals, low in organic matter and allow good drainage for vine roots, creating less green growth and more concentration of flavor within the grape berries.
Summer days are very hot but most nights cool down with moist ocean breezes sneaking in over the Mayacamas Mountains or from Knights Valley to its northwest.
Cabernet Sauvignon is the area’s star variety with Zinfandel coming in a strong second, though the latter commands far less price per tonnage so continues to be outshined by Cabernet in vineyard acreage, save for some important exceptions.
