Our Estate Vineyard

Obsidian Vineyard

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.

Finding Extraordinary Sites

For us, identifying a top-notch vineyard is like hearing a great song for the first time. It’s immediately identifiable. It has no blue-print for duplication. It won’t let go of you.

In a word, it is genuine.

From these extraordinary vineyards, we produce compelling wines year after year, doing our best to read their cues and allow their terroir to shine. The map below illustrates the depth of our obsession. From the cool-climate, redwood fringed Perli Vineyard in the Mendocino County AVA to a collection of wild sites we love in the Bennett Valley AVA, our journeys across Northern California have been exhaustive — but they have been so worth it.
