Winemaker Notes
Notoriously food-friendly, long-lasting and Spain’s most widely planted grape, Tempranillo is the star variety of red wines from Rioja and Ribera del Duero. The Rioja terms Joven, Crianza, Reserva and Gran Reserva indicate both barrel and bottle time before release. Traditionally blended in Rioja with Garnacha, plus a bit of Mazuelo (Carignan) and Graciano, the Tempranillo in Ribera del Duero typically stands alone. Somm Secret—Tempranillo claims many different names depending on location. In Penedès, it is called Ull de Llebre and in Valdepeñas, goes by Cencibel. Known as Tinta Roriz in Portugal, Tempranillo plays an important role in Port wine.
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.
