Introducing J. Moss: A Hands-On, Family-Run Napa Winery That’s Onto Something Special

Introducing J. Moss: A Hands-On, Family-Run Napa Winery That's Onto Something Special 5

This small, hands-on family winery is the result of 50+ years of combined experience in the wine industry between James and Janet Moss. James’ dream has always been to produce quality Napa Valley wines, which he considers to be the ultimate region for producing Cabernet Sauvignon.

James and Janet Moss began pursuing their dream of making artisanal, small production lots of Cabernet Sauvignon in Napa in 1998, beginning with a tiny plot of grapes grown on the Carneros property they had made their home. Their first vintage made its debut at their wedding in 2000, and the excitement around those bottles from friends and family further solidified James’ interest in winemaking, Cabernet Sauvignon, and eventually production in Napa Valley; it was one of a few pivotal moments where the Moss’ knew they were onto something special…

James actually hails from the distribution side, having worked as a sales rep in Texas in the ’90s (more on that, later). The connections he made in Texas, then in California, helped shape his interest and education in winemaking; he learned the intricacies of enology by working alongside names like Mark Jessup, former winemaker from Jessup Cellars, Robert Mondavi, and Opus One, and Gustavo Brambila, former winemaker for Chateau Montelena and Grgich Hills.

And just when you think you’ve figured out where the ‘J’ in J. Moss comes from, James will tell you about his wife, Janet, a 30-year wine industry veteran, and, as James would smile and also tell you, is truly a bedrock for the business today and since the beginning.

After searching for a new, hidden gem to add to our Napa Valley portfolio, we could not be more proud and excited to have come across J. Moss wines earlier this year. These wines are exactly what we were looking for; well-made, thoughtful Cab from a family-run winery.
