Napa Valley Grapegrowers Names Caleb Mosley Executive Director

Press Release

– Napa Valley Grapegrowers, a non-profit 501(c)3 organization, has announced Caleb Mosley as Executive Director as of February 5, 2024. Mosley will lead the organization after serving on its Board of Directors since 2019.

Mosley grew up on a mountaintop vineyard before studying Wine and Viticulture at Cal Poly, San Luis Obispo. He then landed back in the rugged Santa Cruz Mountains in 2006 as the Viticulturist at Ridge Vineyards, Monte Bello, under the tutelage of David Gates and Paul Draper. At the onset of the 2011 vintage, he moved to Araujo Estate in Calistoga to manage the Eisele Vineyard, working with Steve Matthiasson, Bob Gallagher, and Jeff Dawson, while collaborating with winemakers Nigel Kinsman, Francoise Peschon, and Michel Rolland.

​From the Eisele Vineyard, Mosley continued to the estate at Quintessa in Rutherford, bringing technological advances and detailed methodologies to the forefront. In 2016 he was hired as Senior Viticulturist for Michael Wolf Vineyard Services, where he farmed 800 acres spanning Carneros in the south to the far reaches of Calistoga in the north, providing perspective on the entirety and complexity of the Napa Valley. He then joined Matthiasson Family Vineyards in 2021, managing all aspects of Steve Matthiasson’s organic vineyards, growing production and improving facilities while cultivating more obscure varieties such as Ribolla Gialla and Refosco.
