Led by proprietors Nan Tucker McEvoy and Nion McEvoy, we planted vines on the ranch in 2006 in pursuit of a wine that would complement our world-class extra virgin olive oil. We now have five separate vineyards on over 25 acres of land under the care of Farming Manager Samantha Dorsey, who confers with our winemakers regularly, walking the vineyards with them throughout the growing season. 

Maurizio Castelli

Dr. Maurizio Castelli, an agronomist and enologist originally from Pistoia, played an integral part in our creation and evolution as makers of exceptional extra virgin olive oil; working with him again when we began our foray into wine was a natural step. A pioneer who helped to create such renowned wines as Col d'Orcia's Poggio al Vento Brunello di Montalcino Riserva, Mastrojanni's Brunello Schiena d'asino and Poderi Boscarelli's Vino Nobile, Castelli has more than 40 years of experience in winemaking and consulting all over the world, including at the famed Badia a Coltibuono in Tuscany. He travels to California several times a year to work at the ranch during the various stages of our olive oil and wine production, as well as to celebrate each harvest.

Margaret Koski-Kent

In addition to her longtime role as Head Gardener, Margaret Koski-Kent now serves as our Head Winemaker, having studied enology at Napa Valley College and apprenticed with winemakers in Italy and California. Margaret has been at the helm of production of our inaugural vintages, applying her expertise beyond the 800 combined varieties of flowers, vegetables and fruit trees she oversees on the ranch. With a BS in Plant Science, specializing in Landscape Design, Koski-Kent draws on the teachings of Alan Chadwick in her work at McEvoy Ranch, embracing sustainable practices that honor a deep respect for our relationship with the earth.

Blake Yarger

Associate Winemaker Blake Yarger was first introduced to farming while studying Buddhism at Green Gulch Farm and Zen Center at the age of 18. He came to McEvoy Ranch after pursuing Agroecology at UC Berkeley and UC Santa Cruz, spending his first few years in the gardens and the olive mill. Blake's deep love for the land and dream of making Pinot noir from Marin County inform his involvement in all aspects of winemaking, from crush to bottle. His work has given him the chance to explore the undiscovered and distinct qualities of the McEvoy Ranch terroir.
