Julien Howsepian


Kosta Browne
Sonoma, California

Building on the accomplishments of former Co-founders Dan Kosta and Michael Browne, Julien Howsepian leads Kosta Browne’s winemaking, overseeing an acclaimed program that features almost 40 of California’s greatest vineyards.


Julien has earned renown for crafting elegant and intense California wines prized for their thoughtful complexity, character, and age-worthiness. Julien’s wines continue Kosta Browne’s two-decade legacy of creating some of America’s benchmark Chardonnays and Pinot Noirs.


Raised in Northern California’s Bay Area, Julien regularly traveled to France to visit family, including relatives in the wine industry. These early visits kindled Julien’s appreciation for the culture of wine, and led him to UC Davis, where he earned a degree in viticulture and enology.


Prior to joining Kosta Browne, Julien gained invaluable hands-on experience at several venerable California estates and in New Zealand’s acclaimed Hawkes Bay region. “My dream has always been to make world-class wines,” adds Julien. “As a winemaker, it is both humbling and a gift to work with such amazing vineyards. Each one has a fascinating story to tell. For two decades Kosta Browne has been dedicated to telling these stories. To build on this legacy is an honor and a privilege.”
