Don and Charlene Stolo purchased 53 acres of property to call home, located just east of Cambria CA. The coastal property had an existing 9 acre vineyard planted to Chardonnay, Pinot Noir, and Syrah. Soon after their purchase, they were faced with the following choice: continue to sell the high in demand coastal grapes to local winemakers, or produce their own wine.n 2004, with the help of their three children and neighbors, Don and Charlene harvested their first vintage from Stolo Family Vineyard. They bottled 176 cases and officially became part of the wine industry.

Meet Niels and Bimmer Udsen, the dynamic husband-and-wife duo behind Cas­toro Cellars, a fun and inviting winery that has been making waves in Paso Robles since 1983. Their journey began with a simple dream: to create world-class wines from the beautiful grapes of the Paso Robles appellation.

Niels, a Ventura native, first dipped his toes into the wine business while studying Agribusiness at California Polytechnic University in San Luis Obispo. His passion for winemaking, combined with Bimmer’s unwavering support, led them to establish their very own winery in the heart of this thriving wine region.

But the path to success wasn’t conventional. The Udsens embraced what they fondly call the “backwards approach”: they started by making and selling wine, then acquired their own equipment, and finally built their winery and tasting room. Talk about an adventure!

You can visit Cas­toro’s charming tasting room in Templeton, right off scenic Highway 46 West, while their winemaking facility is located in San Miguel on the East Side of Paso Robles—both opened their doors in 1990. With the mentorship of Tom Myers, Cas­toro Cellars’ talented winemaker, the Udsen family has transformed from crafting a few barrels for friends and family into a thriving business.

Today, Cas­toro boasts over 1,400 acres of estate vineyards, all certified organic and SIP certified. Niels and Bimmer have built a brand that reflects their values, focusing on approachability and environmental consciousness. Niels' father, a Danish immigrant and successful businessman, instilled in him a deep appreciation for agriculture and entrepreneurship, which shaped their winery’s foundation.

Niels discovered his love for the wine industry during a senior marketing project for a local winery at Cal Poly. After marrying Bimmer in 1981, he honed his winemaking skills in the cellar of Estrella River Winery, learning every aspect of the craft for five years under the guidance of Tom Myers.

In 1983, armed with experience and a sense of humor, Niels and Bimmer launched Cas­toro Cellars, named after the Italian word for “beaver” (Niels’ long-time nickname). Their motto, “Dam Fine Wine,” perfectly captures their playful spirit!

Cas­toro Cel­lars isn’t just about great wine; it’s about family values, too. Their welcoming tasting room is family-friendly, even offering alcohol-free Zinfandel grape juice for the little ones. Plus, the Udsens prioritize a work environment that understands the importance of family flexibility for their employees. So, whether you’re a seasoned wine lover or just starting your journey, Cas­toro Cellars promises a delightful experience filled with laughter, warmth, and, of course, exceptional wine!
