Winemaker Notes
Beyond the usual suspects, there are hundreds of red grape varieties grown throughout the world. Some are indigenous specialties capable of producing excellent single varietal wines, while others are better suited for use as blending grapes. Each has its own distinct viticultural characteristics, as well as aroma and flavor profiles, offering much to be discovered by the curious wine lover. In particular, Portugal and Italy are known for having a multitude of unique varieties but they can really be found in any region.
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.
