'''Long Valley-Lake County''' is an [[American Viticultural Area]] (AVA) located in the eastern part of [[Lake County, California]], established in April 2023 and encompassing {{convert|7605|acre|km2}}.
A [[transverse valley]] sitting on a [[geologic formation]] known as the Cache Formation, its floor is at {{convert|1322|feet|meter}} above sea level, with foothills rising another 200 to 500 feet. Lake deposits form a soil composed of "[[Tuff|tuffaceous]] and [[Diatomaceous earth|diatomaceous sands and silts]], [[limestone]], gravel, and intercalated volcanic rocks".<ref name="Establish"/> Categorized as a Region III on the [[Winkler scale]], Long Valley's annual recorded rainfall is similar to other Lake County AVAs, between {{convert|27|in|mm}} and {{convert|33|in|mm}}, increasing as one moves west.
During the growing season, winds blowing through the valley cool the vines from the heat of the day. Cool [[Atmospheric river|air drainage]] provides protection from damaging late spring frosts in vineyards in the foothills, while vineyards along the valley floor require overhead sprinklers for protection.
The petition for the Long Valley AVA also requested an expansion of the boundaries of [[High Valley AVA]], which Long Valley borders to the southwest, in order to close a gap, and a modification of the [[North Coast AVA]] in order to fully encompass the new AVA. The [[Alcohol and Tobacco Tax and Trade Bureau|TTB]] agreed to those boundary changes.<ref name="Establish"/>
Cache Creek Vineyards, which is based at the southern tip of Long Valley, and [[Shannon Family of Wines]], which in 2015 acquired 280 acres in the area,<ref name="Bee">{{cite news|url=https://www.record-bee.com/2015/02/09/winery-to-expand-local-vineyards/|journal=Lake County Record-Bee|date=9 February 2015|title=Winery to expand local vineyards}}</ref> were key petitioners to get the region recognized as an American Viticultural Area.<ref>{{cite news|url=https://www.wineenthusiast.com/basics/region-rundown/long-valley-lake-county-ava/|title=In the Shadow of Mt.

As of May 2024, three wineries operate within the Long Valley boundaries: Noggle Vineyards & Winery, Cache Creek Vineyards, and Stonehouse Cellars.
