As I mentioned a while ago, the Calistoga AVA was finally approved after years of negotiations. When the final description was published in the Federal Register and I got right to the mapping of the area (ok, I took some time getting to it).
But here it is! The AVA is located between St. Helena to the southeast and Kellogg on the northwest and is centered around the town of Calistoga.
As always, these maps are done to the best of my puny abilities as a geography nerd and should not be used for land speculation or navigation purposes.
