Justin Seidenfeld

Winemaker

Justin Seidenfeld’s winemaking career began in Sebastopol, California, where he was an intern at Iron Horse winery in 2005.  There, the regular work of the cellar kicked off a quick rise in winemaking responsibilities that landed him a job in 2006 at the venerable Robert Mondavi Winery in Oakville, California. Justin started working for Rodney Strong in the spring of 2010. 

As a harvest enologist at Mondavi, Seidenfeld walked some of California’s premiere vineyards and gained a comprehensive understanding of quality land and viticulture. Continuing on to become an enologist, he took that experience into winemaking and supervised the winemaking of Estancia, Clos du Bois, Simi and others within the Constellation portfolio. Additional responsibilities included overseeing small lot Cabernet Sauvignon and Pinot Noir winemaking.

At Rodney Strong, Justin will work alongside longtime winemaker, Rick Sayre, in the winery’s main cellar. Seidenfeld graduated from the University of California, Davis in 2006 with a B.S. in Viticulture & Enology. 

Justin lives in Santa Rosa with his wife Dena and daughters Madison and Lila.  He enjoys golfing, playing with his daughters and working on his house. As to his inspiration to become a winemaker, Justin notes, “people recalling the occasions that wine makes better and memorable is the reason I make wine. Hearing about how and when someone enjoyed a wine I made inspires me.”
