Named after the black volcanic glass in the bedrock beneath the vines, our estate vineyard is one of the most unique in California. Here, the vines grow on a steep perch above the Franz Valley floor in the Knights Valley. While Obsidian is one of our warmest sites, it is also our most free draining soil, which leads to extremely low vigor, tiny berries and a flavor concentration that is nothing short of ethereal.
