Wine Searcher: Napa’s Newest AVA Carves A Space
SF Chron: Napa Valley just got its first new official wine region in 13 years
I took a peek through the links, thanks for posting them. Couldn’t find anywhere that named the vineyards or wineries that will be contained within the new AVA. Anyone know where to find a list of those?
this area is apples to oranges from st helena, howell mountain.
a desperate need for this ava has been met. kudos.
In what way? I don’t know anything about this AVA in particular, and little about Napa in general.
sarcasm.
I found an article that said 30 wineries in that AVA. Viader, Somnium (Danica Patrick), and Bremer. Haven’t seen a full list though. Nothing I’m particularly excited about so far.
30 vineyards. As stated above, in the Registry, and in some of the articles linked.
Oops, yes, Vineyards not wineries!
Is this a good thing or do I need another napa AVA like I need a hole in my head?
it does fill that gap like a puzzle piece
Awful AVA name. Couldn’t have went with Bell Canyon or something? I’m guessing Sanitarium didn’t have the cachet.
Can anyone clue us in to what the “ethnic slur” name was for this area?
The sad reality is that the AVA’s don’t get used much, because it’s easier to make money from the unwashed masses if you designate it Napa Valley rather than the AVA that nobody’s except the terminally included have heard about… 
@Roy_Piper did send me a rough “ranking” list of in the AVA’s in Napa a few years back as a guide. Here they are in order of “importance” (take con grano salis):
Everything below 6-7 probably best to designate Napa Valley. And depending on our market, maybe all of it is best designated Napa.
I’m not certain of its exact location but I’d suspect Ecotone Vineyard (formerly “Thorevilos“) would now fall into this Crystal Springs AVA designation. This vineyard has always been described as sitting above St. Helena AVA and below Howell Mountain AVA.
Roy Piper’s list is incomplete, as it does not include Diamond Mountain District.
All due respect to Roy but Coombsville is criminally underrated. Such good Cabernet growing down there.

The SWE has a copy of the original petition on their blog, which adds detail:
(edit: and here’s a link to their post, since I guess hotlinking without it is kinda rude, sorry) SWE blog post on Crystal Springs AVA
FYI - Pritchard Hill is not an official AVA. While we would love to be able to use it on our Stagecoach Vineyard cab (as our block is in that region of the vineyard) the name is owned by the Chappellet Family.
There are now 17 nested AVA’s in Napa Valley with the addition of Crystal Springs. The NVV website contains some good info on each one. Right side of screen has the complete list and when you click on an AVA it launches a detailed page.
I’m happy to see a new AVA for no other than reason than it seems to be have been achieved amicably… but does anyone else think this might be a long-game marketing tactic for Burgess?
Obviously the winery was sold so it doesn’t affect Steven Burgess himself anymore, but we also know Lawrence loves prestige. Given the extremely small footprint of the AVA, it seems the “exclusivity” would play well in marketing materials.
Karen, didn’t know Pritchard Hill was not an AVA.
Atlas Peak is another one.
