Bryant Family Vineyard is a California wine estate in the Napa Valley, founded by businessman Donald L. Bryant Jr. and his ex-wife, Barbara Bryant. Known for their 100% Bryant Family Vineyard Cabernet Sauvignon wines grown on their Pritchard Hill estate, Bryant Estate was one of the original cult wines to emerge during the early 1990s, along with wineries such as Screaming Eagle and Harlan Estate. Low production levelsand high demand for the wines have driven prices to the upper echelon of wines produced in the United States.As of 2009, Bryant Estate produces two additional labels, "Bettina" and "DB4". Bettina is a parallel wine to Bryant Family Vineyard Cabernet, made of grapes purchased from some of viticulturist David Abreu's vineyard sites. DB4 is a second wine, made of declassified wine from both Bettina and Bryant Family Vineyard labels.

Rancho Catacula was a 8,546-acre (34.58 km2) Mexican land grant in present-day Napa County, California given in 1844 by Governor Manuel Micheltorena to Joseph Ballinger Chiles. The grant was located along Chiles creek in the Chiles Valley east of St. Helena.

Lake Hennessey is a reservoir in the Vaca Mountains, east of St. Helena and the Napa Valley, within Napa County, California. The reservoir is formed by Conn Creek Dam, built in 1948 (1948) across Conn Creek. Construction of the earthen dam was authorized by the United States Congress when it passed the Flood Control Act of 1944 in order to mitigate flooding downstream in Napa, California.Funding for the dam was never appropriated by Congress, so in 1946 the City of Napa took on the project and built it at a cost of $550,000 dollars plus $250,000 for the land. The cost of laying the 36 inches (910 mm) diameter pipeline from the dam to the city of Napa was $1.7 million. The 30 miles of pipe for the project was manufactured at the Basalt Rock Company plant located south of Napa. The design of the dam did not include a way to drain water from the reservoir when it comes close to full capacity. Once the lake is full, water drains from a spillway causing potential flooding dangers downstream. The reservoir and pipelines are maintained by the city of Napa, and it is its primary source of water. When the reservoir reaches its capacity, outflow reaches San Pablo Bay via Conn Creek to the Napa River. The lake was named after Edwin R. Hennessey. Hennessey was a local civic leader who played a role in the development of the Conn Valley reservoir.

The waters of the reservoir are impounded by Rector Creek Dam, which was built in 1946 across Rector Creek.

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 30 °F (17 °C) 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 315,000 acres (127,476 ha) in five counties, including in north Atlas Peak.
