  • About
    The husband and wife team of Niels and Bimmer Udsen established Castoro Cellars in 1983 with the goal of producing world-class wines from Paso Robles-appellation grapes. Each vintage presents a new challenge the Castoro team is more than willing to constantly and creatively experiment. This on-going research is only one of the things that ensure they meet their goal.

    Niels' long-time nickname "Beaver," evolved further when he was working in Italy and his friends soon took to calling him "Il Castoro," which is beaver in Italian. The name and the motto stuck. Castoro Cellars' "dam fine wines" sport a picture of a beaver on each label.

    Castoro Cellars currently has over 1,400 acres of Estate vineyards that are 100% certified organic by CCOF. All of the vineyards are also SIP Certified, which stands for sustainability in practice. Sustainable farming and wine-making have been at the forefront of Castoro's mission since its inception. Castoro is also home to one of the largest solar arrays in Paso Robles, designed to offset all of the winery's energy use. In total, we produce more than 2 million kWh across many vineyards and facilities.

    Beyond the wine, Castoro features live music year-round, Yoga Brunch classes, an 18 hole disc golf course, and the annual Whale Rock Music & Arts Festival every September. If you love music, wine, yoga, craft beer, and art all in a family-friendly environment, Whale Rock Music & Arts Festival is for you!
