Palmaz Vineyards is a family-owned and -operated gravity-flow, gravity-finish winery and historic estate at the southern end of Napa Valley. The estates centerpiece is the Cave, an 18-story, 100,000-square-foot subterranean winery that required seven years to complete. There, the family combines the latest technology with time-honored craftsmanship to make, among much else, their signature Palmaz Cabernet Sauvignon.
First established in 2005, Porter Family Vineyards is owned and operated by Tom and Beverly Porter and is located in the hills on the edge of the Coombsville Region east of the town of Napa. It has wonderful views looking North into the Napa Valley and it backs up to the Skyline Wilderness Park. A unique aspect to this boutique winery is that it is entirely underground, made up their 17,000 square feet of caves. Due to the owners’ expertise in the computer software industry, the winery is known for its high level of technology controlled systems operating the caves and the vineyards. Cabernet Sauvignon and other red wines are their specialty. The sandpiper bird is their signature picture and label on their bottles, symbolizing the sandpiper fossils found on their property when they were digging the cave.
