The Atlas Peak AVA is an American Viticultural Area located within Napa Valley AVA just northeast of the city of Napa. The appellation sits on a higher elevation than most of Napa's wine region which limits the effects of the cool fog coming in from Pacific Ocean. The westward orientation of most vineyards on the Vaca Mountains also extends the amount of direct sunlight on the grapes. The soil of this AVA is volcanic and very porous which allows it to cool down quickly despite the increased sunlight. The area has a fairly significant diurnal temperature variation upwards of {{convert|30|F-change|C-change}} between daytime and night. This contributes to the balance of acidity that grapes from Atlas Peak vineyards are known to have.

In August 2020, Atlas Peak was evacuated due to the Hennessey Fire, which resulted in the burning of over {{Convert|315,000|acre|ha|0|abbr=on}} in five counties, including in north Atlas Peak.{{cite web|title=Hennessey Fire Information|url=https://www.fire.ca.gov/incidents/2020/8/17/hennessey-fire/|website=CAL FIRE|accessdate=17 August 2020|archive-date=18 August 2020|archive-url=https://web.archive.org/web/20200818015057/https://www.fire.ca.gov/incidents/2020/8/17/hennessey-fire/|url-status=dead}}
