Winemaker Notes
Sémillon has the power to create wines with considerable structure, depth and length that will improve for several decades. It is the perfect partner to the vivdly aromatic Sauvignon Blanc. Sémillon especially shines in the Bordeaux region of Sauternes, which produces some of the world’s greatest sweet wines. Somm Secret—Sémillon was so common in South Africa in the 1820s, covering 93% of the country’s vineyard area, it was simply referred to as Wyndruif, or “wine grape.”
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.
