Molly Lonborg is a Paso Robles winemaker devoted to organic and regenerative farming and to crafting wines that speak honestly of place. Raised in the coastal village of Mendocino, Molly grew up surrounded by wild landscapes that shaped her curiosity about the natural world. She went on to earn a B.S. in Earth Sciences with a concentration in Wine and Viticulture from Cal Poly, San Luis Obispo, and spent a year studying geology at the University of Otago in Dunedin, New Zealand—an experience that deepened her understanding of terroir and its quiet influence on a wine’s soul.

Molly began her winemaking journey with harvest roles in Edna Valley and Paso Robles before joining Halter Ranch in 2011. There, she rose from Lab Manager and Cellar Assistant to Enologist, Assistant Winemaker, and finally Associate Winemaker, gaining a reputation for precision, curiosity, and a strong connection to the vineyard. In 2019, Wine Business Monthly named her “Winemaker of the Month,” recognizing her as a rising voice in California wine.

In 2020, Molly took on the role of Head Winemaker at Alta Colina Vineyard & Winery, where she further refined her craft with Rhône varieties and embraced a farming-first approach to winemaking. During this period, she founded Little Soul, a small, intentionally crafted label rooted in her love for expressive, vineyard-driven wines.

In early 2025, Molly became Senior Winemaker at Booker Vineyard in the Willow Creek District. There, she oversees all winemaking and has been a driving force in the estate’s organic wine certification and continued commitment to regenerative practices. That same year, Wine Business Monthly honored her as a “Viticulture and Winemaking Star” for her leadership, mentorship, and advocacy for inclusivity within the industry.

Molly lives on a ranch in Paso Robles with her husband, Jordan Lonborg, a Regenerative Vineyard Consultant for Coastal Vineyard Care; their two children, Alma and Ziggy; and their loyal dog, Desmond. When she’s not in the vineyard or cellar, she loves camping, hiking, traveling, live music, and nurturing a growing array of organic crops.
