This is a great little winery along the Foxen Canyon trail. If you want a winery where the owners pour and you can actually talk about winemaking and the whole experience you get it here. Tres Hermanas does not make super jammy Central Coast wines but rather produces numerous wines in a more European style...lower in alcohol, higher in acid and basically more food friendly. I will have to say I enjoy 90% of what they produce. Their Tres Hermanas Cuvee is incredible as is there Nebbiolo, Refosco, Syrah/Sangiovese blend and Muscat Cannelli.

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!

The tasting rooms and grounds are beautiful and well kept. There are shaded areas to enjoy a glass of wine, as well as a great deal of manicured lawns to have a picnic or catch some rays. If you arrive with sufficient time, they gladly give tours of the production rooms, which I found interesting. Each time I've gone to a tasting here, the staff has been welcoming and informative, without being pretentious. The selection of wines for the regular tasting is good and includes several of my favorite wines from this winery. They usually give away the tasting for free if you buy a bottle.

Love private tours? Perfect for both families and friends. It comes with both a walk tour and a formal sit-down tasting paired with complementary cheese and chocolates. Can a girl ask for more? I'm in particular a fan of their Cabernet Sauvignon - very bold without being overtly tannin-ridden and their Violetta dessert wine - seriously off the charts!
