Atlas Peak is a sub-region of Napa County, and the name refers to one of the highest mountains in the area, with an elevation of 2,663 feet. Atlas peak is at the southern edge of the Vaca Mountains, which form the eastern flank of the Napa Valley. Vineyards here are thus significantly higher in elevation than those on the valley floor, resulting in cooler temperatures. As such the resultant wines are firm, classic styles with pronounced acidity and less of the power and forward fruit of their valley floor cousins.

Cabernet Sauvignon is king here and accounts for well over half of the vineyard plantings, with Zinfandel, Merlot, Syrah, and Sangiovese rounding out the reds. Atlas Peak's white wines are almost exclusively made from Chardonnay. While many wineries purchase Atlas Peak fruit, Antica Napa Valley (Antinori) and Atlas Peak Vineyards are the largest and most visible of the wineries located within the district itself.
