As the oldest continually operating winery in Arizona, Sonoita Vineyards has had plenty of time to hone its craft. Its enduring success is partly due to its hillside location, which, although lovely for humans, is even better for grapes. Nestled on a south-facing slope, the 30 acres of vineyards are protected from much of the area's harsh weather and supplied with plenty of water by root-guarding berms. This setting has proven ideal for 10 varieties of grape vines, whose fruit becomes Sonoita Vineyards' 12 wines and whose stems and leaves go back into the soil to fertilize more grapes. These vintages include crisp, sparkling whites and an earthy blend of merlot, cabernet sauvignon, and syrah grapes. Perhaps the popular vintage is the cabernet sauvignon, which is so celebrated that it's been served at a presidential inauguration gala and used to christen every new vice president.

The flavor profiles of these wines come to life during staff-guided group tastings and wine flights in the tasting room. These tastings aren't the bar's only attractions: the wine-production facilities are visible from the bar, and visits during the late-summer harvest season provide a glimpse into the winemaking process as it happens. Meanwhile, an outdoor portico offers a space for picnics and views framed by mountain ranges.
