About Us


Sometimes dreams come true…

Our dream was to create high quality, hand crafted, small lots of cabernet sauvignon from top Napa Valley appellations.  In vintage 2000, we made our first barrels from merlot grown on the Carneros property where we lived.  We knew we were on to something special!  For several more years, while working a full time job in the wine industry, James spent evenings and weekends learning the intricacies of winemaking.  James was fortunate to have the opportunity to work alongside two phenomenal winemakers in the Valley;  Mark Jessup, former winemaker from Jessup Cellars, Robert Mondavi and Opus One and now winemaker at J. Gregory Wines, and subsequently with Gustavo Brambila, former winemaker for Chateau Montelena, Grgich Hills and now part owner/winemaker of Gustavo Wines.

Dreams do come true but not before a lot of hard work!  In 2010 we opened our own winery located in the southernmost part of Napa located in the Wine Crusher District, Napa's boutique artisan winemaking district. 

Our name on every bottle is a promise of the highest quality.  Everything is crafted by hand, then patiently vinified in separate single vineyard blocks and barrel lots in limited quantities, with production steadily increasing each year.  Our passion is to produce not just good, but great wines that reflect their vintages and single vineyards from top appellations in the Napa Valley.

Our winemaking style is to produce age-worthy yet full bodied, intense, complex and elegantly balanced wines that reflect our attention to detail and appeal to everyday wine drinkers as well as wine connoisseurs.  Some people have called it “cult wine.”

We hope each wine will provide a unique and rewarding experience and will show you the amount of care that goes into each bottle of J. Moss wine. We invite you to share our family's passion for fine wines and the tradition of making memorable cabernets in the Napa Valley!

Come and visit us and share the dream on your next trip to the Napa Valley!
