Who We Are

Joshua and Sarah Stewman, Winemakers and Principals of Roberts Ranch Vineyards

Joshua and Sarah Stewman

Winemakers, Principals

Joshua and Sarah have always had their hands in the dirt, but pursuit of viticulture began in earnest in 2008 with the planting of the first 300 vines for our Family Farm block. Planting, working together with our 5 sons through the growing seasons, and sharing harvest with extended family and friends has marked our years now for more than a decade. We've also been grateful for the early guidance of experienced Central Coast fellow winemakers who convinced us to pursue the more restrained old-world winemaking techniques, letting native yeasts do their work to produce the complexity of flavor you'll find in your glass. We love to talk architecture and libraries too (our other jobs) and look forward to meeting you at the cellar - Salute!

Randall and Sonja Swanson, Principals and Head of Marketing at Roberts Ranch

Randall & Sonja Swanson

Marketing, Principals

These two are seasoned travelers who have often enjoyed sampling wines from around the world. As their palates have developed and matured over the years, a love has grown for the world's most popular varietal, Pinot Noir. This light-bodied red wine is also loved everywhere for its beautiful red fruit, flower, and spice aromas that are accentuated by a long smooth finish and is delicious with almost any cuisine. Randall and Sonja invite you to try our Roberts Ranch Pinot Noir with good food, family, and friends. Please take this precious time together, to talk and laugh, and enjoy one another's company, for the purpose of ever growing stronger relationships, which is indeed the ultimate spice of life!

Tom Stewman


Vineyard Manager

Tom is the real deal. This is a guy that keeps the tractor running, who builds the new fence, whose cowboy boots are a bit well worn.  He grew up on the family property next door and has a keen love for the mountains and his family.  He's a fun uncle! He has the mind of an engineer, and finds delight in making our whole family wine growing/wine making process run just a little bit smoother. When he’s not dropping into a nice wave at Davenport Landing, he’s racing the ATV up the hill to check on the vineyard irrigation .
