Hourglass produces wines from St. Helena, a region celebrated for structured Cabernet Sauvignon and Bordeaux varietals. The winery's portfolio centers on red blends and single varietals drawn from the Blueline Estate vineyard. Blueline Estate 36-24-36, a five-varietal blend of Merlot, Cabernet Sauvignon, Malbec, Cabernet Franc, and Petit Verdot, anchors the range. The Premiere Napa Valley Cabernet Sauvignon offers a focused expression of the region's signature grape, while a Cabernet Franc rounds out the core offerings. Wines from Hourglass have been assessed by Wine Enthusiast, Decanter, Wine Advocate, Wine Spectator, and Falstaff.
