Ampelos has been a family endeavor from the start.Initially “corporate folks”, we loved getting away to the Sta. Rita Hills on the weekends and dreamt of one day planting our own vineyard and making wines. A cancelled meeting in New York on the morning of September 11, 2001 helped us to realize that someday was today! Driven by a deep love and passion for the art of viticulture. We are truly a small boutique winery producing about 3500 cases a year. Our focus is viognier, rosé of syrah, pinot noir, syrah and grenache.

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!

We had a great time here. We stepped in here while waiting for another winery to open. The very first thing we noticed when we opened the door was the intoxicating scent of wine. We were able to take a self-guides tour around and realized the large barrels were right in the open, which was why the facility had that lovely sweet wine smell. Tour was timed perfectly, not too long, but not too short, and we had a super nice tour guide. Wine tasting after the tour was extra fun.
