About Us

Sometimes dreams come true…

The dream was to create high quality, hand crafted, small lots of cabernet sauvignon from top Napa Valley appellations. In vintage 2000, the Moss’ made their first barrel from merlot grown on the Carneros property where they lived. They knew they 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, a native Texan 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

Janet Moss moved from Boston to California in 1990 and her first job in California was working for the world renowned sparkling wine facility Domaine Carneros. During her 10 year tenure at Domaine she attended classes at the Napa Valley College to expand her knowledge of the wine industry, she continued to go on and get her winemaking and viticulture degree in 1999.

Dreams do come true but not before a lot of hard work! In 2010 they opened their own winery located in the southernmost part of Napa located in the Wine Crusher District, Napa's boutique artisan winemaking district. To support the growing dreams and cellar, they brought on raising star consulting winemaker, Julie Hagler Lumgair to assist with their award winning wine program.

The J. Moss 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. Their passion is to produce not just good, but great wines that reflect their vintages and single vineyards from top appellations in the Napa Valley.

James and Janet 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. They invite you to share in their 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!
