Steve Brady, founder and proprietor of On Q Wines, crafts ultra-premium wines produced from the finest Napa Valley grapes grown in the Coombsville sub-appellation. 

As a young man growing up in the Napa Valley, Steve learned to appreciate and respect the significance of the region’s winemaking history. In addition to his love for wine, Steve’s longtime hobby of playing trumpet soon evolved into a semi-professional endeavor. As his passions for both wine and music grew, Steve realized the creation of extraordinary music and the crafting of world-class wine shared a common element—timing.

Trained as a Marine Engineer and having spent many years at sea, Steve’s detail-oriented, meticulous nature couple with his artistic side and enable him to create wines of high-quality, elegance, and sophistication to be enjoyed by both discriminating wine connoisseur and novice alike.

Steve planted his first vineyard in 2003 with the help from his three daughters, Megan, Amanda, and Marina—each of whom have been involved in his winemaking endeavors since its inception. He produced his first wine with the 2005 vintage, a Rhone blend that received rave reviews from friends, family, and local wine competitions.

In 2010, Steve launched On Q Wines with an indelible vintage that received rave reviews and high scores. Steve's Consulting Winemaker, Maayan Koschitzky, assists Steve in winemaking decisions and works directly alongside in the cellar.
