The Mansfield-Dunne Family

This family was borne out of a shared passion for great estate winemaking, determination, and humility in the face of land and nature. It started with a fateful dinner in 2001 where the dream of developing a vineyard was vocalized and from that moment, we’ve been together as one working to make the dream of Mansfield-Dunne a reality.

John Peterson

John Peterson

As a lifelong lover of Pinot Noir and Chardonnay, John Peterson long dreamed of developing a vineyard. After eight years of scouring California for the perfect vineyard for his ambitions, 300 acres of rugged scrub land became available and his dream became a reality when the land that would become Cortada Alta Vineyard was purchased in 2009. Only after four plus years of drilling water wells and four dry holes was John confident enough in a reliable water supply to start planting. Developing the vineyard hasn’t been an easy road, it’s been filled with fits and starts, but his vision and steadfast determination have helped Mansfield-Dunne stay the course.

Ed Kurtzman

Ed Kurtzman

With a long track record of making acclaimed wines in the Santa Lucia Highlands, Ed Kurtzman has depth of knowledge and intuition that few can match. Starting in 1994, he’s overseen winemaking through historic vintages at a variety of well known brands, yet Peterson and Cortada Alta Vineyard have offered a unique challenge. Ed’s wide range of experience allows him to perfectly express the specificity of our two estate vineyards and his style is imprinted on Mansfield-Dunne.

Ruben Balderas

Ruben Balderas

Ruben Balderas grew up in the vineyard. His father managed Martin Ray Winery along with Mount Eden Vineyards. It’s fair to say that viticulture and winemaking are in his blood. From tasting Cabernet Sauvignon at age nine to being hired straight out of high school to work in the cellar — Ruben’s life has been marked by being the backbone of numerous Central Coast wineries. It’s Ruben’s careful vineyard management and farming that allow our vineyards to express themselves to purely.
