Jac Cole, Winemaker

Jac Cole

After graduating from the University of California Berkeley with a degree in Biology in 1972, Jac followed his growing passion for winemaking to the Masters Program in Enology at California State University Fresno. Jac began his professional odyssey as an intern at Chateau St. Jean in Sonoma County, and from there, wound his way through Napa Valley gathering expertise and experience with such prestigious wineries as Stag’s Leap Wine Cellars, Stags’ Leap Winery, and S. Anderson Vineyards.

Jac has had the rare fortune of acquiring a remarkable depth of knowledge and experience along his winemaking path, as well as his valued friendship with Spring Mountain Vineyard manager, Ron Rosenbrand. Together they are dedicated to the concept that the world’s greatest wines are the direct result of the work done in the vineyard.  Their focus has been on the nuance of clone and rootstock, the balance of canopy and fruit, and the determination of the point of perfection for harvest. Armed with a combination of gleaned experience, passion and friendship, Jac comes to Spring Mountain Vineyard to lift wine quality to even greater heights.

Jac lives on a picturesque two-acre vineyard on Howell Mountain with his wife, Ami.

Ron Rosenbrand, Vineyard Manager

Ron Rosenbrand

Born and raised in Saint Helena and into a winemaking family, Ron’s passion for grape growing came at an early age.  His father, well known winemaker Theo Rosenbrand - whose achievements at Beaulieu and Sterling Vineyards are revered by wine collectors today, knew that great wines were made in the vineyard, not in the winery.  Certainly influenced by this fact, Ron chose viticulture, not winemaking; graduating from the University of California at Davis in 1981. 

After studying French viticulture in the Jura, Ron spent 21 years growing wine at Charles Krug, V. Sattui, and Spring Mountain Vineyard. Before being reunited on Spring Mountain he shared his passion and dedication for six years with winemaker Jac Cole at Krug. Ron is dedicated to using his knowledge of terroir, rootstock and clonal selection, vine stress and canopy management to realize the full potential of each of Spring Mountain’s 135 vineyard sites.

Ron resides in Napa with his wife Jacqueline and their 5 children, Brian, Amy, Conner, Cole, and Alexi.
