With the christening of the winery at Blueline and its distinct single-varietal wines, Hourglass has entered an exciting new phase of its evolution. A brand synonymous with terroir-driven, modern Napa wines of the highest caliber, its goal is and will always remain the same: To capture the essence of two of Napa Valley's most expressive vineyard sites in bottled form, and to have the honor of sharing them with you and your families for decades to come.

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.

Capable of a vast array of styles, Sauvignon Blanc is a crisp, refreshing variety that equally reflects both terroir and varietal character. Though it can vary depending on where it is grown, a couple of commonalities always exist—namely, zesty acidity and intense aromatics. This variety is of French provenance. Somm Secret—Along with Cabernet Franc, Sauvignon Blanc is a proud parent of Cabernet Sauvignon. That green bell pepper aroma that all three varieties share is no coincidence—it comes from a high concentration of pyrazines (herbaceous aromatic compounds) inherent to each member of the family.
